2 FIRST AID FOR ELECTRICAL SHOCK AND SAFETY RULES

2.1 FIRST AID FOR ELECTRICAL SHOCK

Do not touch the bare hands until the circuit has been opened. pen the circuit by switching off the lineswitches. If that is not possible protect yourself with dry material and free the patient from the con-ductor.

2.1.1 Artificial respiration

It is important to start mouth respiration at once and to call a doctor immediately. suggested procedurefor mouth to mouth respiration method is described in the Tab.1.

2.1.2 Treatment of burns

This treatment should be used after the patient has regained consciousness. It can also be employed whileartificial respiration is being applied (in this case there should be at least two persons present).

Warning

• Do not attempt to remove clothing from burnt sections

• Apply dry gauze on the burns

• Do not apply ointments or other oily substances.

Tab.1 - Artificial respiration

2.2 SAFETY RULES

When the equipment units are provided with the plate, shown in Fig.1, it means that they contain compo-nents electrostatic charge sensitive.

Step Description Figure

1

Lay the patient on his back with his arms parallel to the body. If the patient is laying on an inclined plane, make sure that his

stomach is slightly lower than his chest. Open the patients mouth and check that there is no foreign matter in mouth (den-

tures, chewing gum, etc.).

2

Kneel beside the patient level with his head. Put an hand under the patient’s head and one under his neck.

Lift the patient’s head and let it recline backwards as far as possible.

3

Shift the hand from the patient’s neck to his chin and his mouth, the index along his jawbone, and keep the other fingers

closed together.

While performing these operations take a good supply of oxy-gen by taking deep breaths with your mouth open

4

With your thumb between the patient’s chin and mouth keep his lips together and blow into his nasal cavities

5

While performing these operations observe if the patient’s chest rises. If not it is possible that his nose is blocked: in that case open the patient’s mouth as much as possible by pressing on his chin with your hand, place your lips around his mouth and blow into his oral cavity. Observe if the patient’s chest heaves. This second method can be used instead of the first even when the patient’s nose is not obstructed, provided his

nose is kept closed by pressing the nostrils together using the hand you were holding his head with. The patient’s head must

be kept sloping backwards as much as possible.

6

Start with ten rapid expirations, hence continue at a rate of twelve/fifteen expirations per minute. Go on like this until the patient has regained conscious–ness, or until a doctor has as-

certained his death.

8 DESCRIPTION OF THE MODULAR IDU FOR 2 OR 34 MBIT/S TRIBUTARIES

8.1 1+0/1+1 MODULAR IDU VERSION

Description that follows is referring to LIM/CONTROLLER/RIM module the Modular IDU consists of.

8.1.1 LIM

The LIM performs the following operations:

• multiplexing process of the input tributaries

• aggregation of the multiplexed signals along with services through a Bit Insertion circuit

• processing in digital form of the baseband part of the QAM modulator (the IF part of the QAM mod-ulator takes place within the RIM

• duplication of the digital processed signal to supply two RIMs in 1+1 versions. In the full duplicatedversion the changeover occurs at tributary level.

Different baseband structures and digital processing of the signal to be forwarded to the QAM modulator/demodulator is produced by a “chip set”. Controls to the chip set and status/alarm reporting from the chipset are given/received by main controller within the CONTROLLER module.

8.1.2 Circuit description

Tx side

Refer to Fig.34.

The 2/34 Mbit/s input signal is code converted from HDB3 to NRZ format before being multiplexed. Themultiplexing scheme depends on the number and the bit rate of the input tributaries.

Attached figures show different multiplexing scheme as follows:

• Fig.35 – 2/34 Mbit/s single tributary multiplexing. The mux performs stuffing operation and gener-ates a proprietary frame to be sent to the Bit Insertion. Opposite operation occurs at the Rx side.

• Fig.36 – 2x2 Mbit/s multiplexing. The mux performs stuffing operation on each single tributary andgenerates a proprietary frame embedding the two tributaries to be sent to the Bit Insertion. Oppo-site operation occurs at the Rx side.

• Fig.37 – 4x2 Mbit/s multiplexing. The mux aggregates the four 2 Mbit/s tributaries generating a8448 kbit/s frame as per Recc. G.742. The multiplexed signal is then sent to the Bit Insertion. Op-posite operation occurs at the Rx side.

• Fig.38 – 8x2 Mbit/s multiplexing. The eight 2 Mbit/s tributaries are grouped in two 4x2 Mbit/s groupseach of one generating a G742 frame structure at 8448 kbit/s to be sent to the next Bit Insertion.Opposite operation occurs at the Rx side.

48 ALS - MN.00183.E - 003

• Fig.39 – 16x2 Mbit/s multiplexing. The sixteen 2 Mbit/s tributaries are grouped in four 4x2 Mbit/sgroups each of one generating a G.742 frame structure at 8448 kbit/s. A further multiplexing of theachieved four 8448 kbit/s streams will generate a frame structure at 34368 kbit/s as per Recc.G.751. This latter is to be sent to the Bit Insertion.The 2 Mbit/s wayside undergoes stuffing processbefore being sent to the Bit Insertion. Opposite operation occurs at the Rx side.

• Fig.40 – 32x2 Mbit/s multiplexing. This version consisted of two LIMs (master and slave) each ofone manipulating two 16x2 Mbit/s signals. Each of one will generate a 34368 kbit/s frame structureas per Recc. G.751.The two signals are sent to the Bit Insertion within the master LIM for aggregation and stuffing proc-ess. The 2 Mbit/s wayside undergoes stuffing process before being sent to the B.I. Opposite oper-ation occurs at the Rx side.

• Fig.41 – 2x34 Mbit/s multiplexing. The two 34368 kbit/s tributaries are directly sent to the Bit In-sertion for aggregation and stuffing process. Opposite situation occurs at the Rx side.

In addition to the tributary mux, an additional service mux is provided for aggregation of various servicesignals interfaced by Controller module.

The multiplexed tributary and service signals are then sent to the B.I. for aggregate frame generation oc-curring at the following bit rate depending on various versions implemented:

Tab.9 - Aggregate frame

The aggregate frame contains:

• the main signal from the MUX(s)

• the framed service signal from the service MUX

• the EOC signals for supervision message propagation towards the remote equipment

• the frame alignment word

• the bits dedicated to the FEC.

All the synch. signals to perform multiplexing (demultiplexing) and BI (BE) process are achieved from a x0at 38.88 MHz

The LIM also includes the processing in digital form (see Fig.34) of the modulating signal to be sent to themixers of the QAM modulator within the RIM.

The digital process includes:

• serial to parallel conversion

• differential encoding

• generation of the shaped modulating signals I and Q to be sent to each individual RIM.

Rx side

Refer to Fig.42.

From the two RIMs the LIM is receiving the I and Q analogue signals then digital converted for the followingprocessing:

2 Mbit/s 2430 kbit/s

2x2 Mbit/s 4860 kbit/s



16x2/34 Mbit/s 38880 kbit/s

ALS - MN.00183.E - 003 49

• clock recovery

• frequency and phase carrier locking

• baseband equalisation and filtering

• bit polarity decision

• differential decoding

• parallel to serial conversion to recover the aggregate signal at the receive side.

The aggregate signal is then sent to a frame alignment circuit and CRC analysis and then to the error cor-rector. The errors uncorrected by the FEC are properly counted to achieve:

• BER estimate measurement

• radio performances

HBER/LBER/Early Warning Alarm roots for monitoring purpose and Rx switching operation are taken di-rectly from CRC circuit before FEC correction.

The Rx switching receives the two aggregate signals and performs signal selection under the control of alogic circuit according with Tab.10.

The changeover is error free and the system has built in capabilities of minimising the passed errors duringthe detection time, such as the early warning criteria. The hitless switching facility provides automatic syn-chronisation of the two incoming streams up to a dynamic difference of ± 7 bits; additionally, the switchingunit is also capable of compensating static delays between the two incoming streams of up to ±7 bits. Atthe output of the Rx switch the Bit Extraction separates the main signal from the services and then, aftera proper demultiplexing process as previously described, sends them to the output interface lines.

• IF part of the QAM modulator

• IF part of the QAM demodulator

• power supply

• telemetry IDU/ODU

8.1.3.1 QAM modulator

I and Q signals from LIM are connected to a 4 or 16QAM programmable modulator. It consists of the fol-lowing circuits:

• recovery low pass filter to eliminate signal periodicity

• two mixers for carrier amplitude and phase modulation process

• 330 MHz local oscillator

• a 90° phase shifter to supply two mixers with two in quadrature carriers

• a combiner circuit to generate the QAM modulation

The thus obtained 330 MHz QAM modulated carrier is then sent to the cable interface for connection withODU.

8.1.3.2 QAM demodulator

At the receive side, from the cable interface, the 140 MHz QAM modulated carrier is sent to the QAM de-modulator passing through a cable equalizer circuit. The QAM demodulator within the RIM extracts the Iand Q signals to be sent to the digital part of the demodulator within the LIM.

8.1.3.3 Power supply

The –48 V battery voltage feeds the IDU and ODU circuitry. The service voltages for the IDU feeding areachieved through a DC/DC converter for +3.6 V generation and a step down circuit for –5V.

Both voltages are protected against overvoltages and overcurrents.

The power to the ODU is given by the same battery running through the interconnection cable.

An electronic breaker protects the battery against cable failure.

8.1.3.4 Telemetry IDU/ODU

The dialogue IDU/ODU is made–up by the main controller and associated peripherals within the ODU. Con-trols for ODU management and alarm reporting is performed making use of a bidirectional 388 kbit/sframed signals. The transport along the interconnecting cable is carried out via two FSK modulated carri-ers: 17.5 MHz from IDU to ODU; 5.5 MHz from ODU to IDU.

ALS - MN.00183.E - 003 51

8.1.4 CONTROLLER

The controller module performs the following:

• interfaces the service signals

• houses the equipment software for equipment management

• interfaces the SCT/LCT program through supervision ports

• receive external alarms and route them to relay contacts along with the internal alarms generatedby the equipment.

Warning: lithium battery inside, refer to national rules for disposal.

8.1.4.1 Service signals

The controller offers an electrical interface to the following three service channel options:

• 9600 baud/V28 with digital party line or in alternative 2x4800 baud/V28 – 9600 baud V28/RS232synchronous/asynchronous channels

• 64 kbit/s/V11 codirectional or contradirectional

• 2 Mbit/s wayside G.703.

The service channels thus interfaced are then sent to the LIM for MUX/DEMUX processing.

8.1.4.2 Equipment software

Equipment software permits to control and manage all the equipment functionality. It is distributed on twohardware levels: main controller and ODU peripheral controllers.

The dialogue between main and peripheral controllers is shown in Fig.44.

Main controller

The activities executed by the main controller are the following:

• Communication management: it makes use of SNMP as management protocol and IP or IP over OSIas communication protocol stacks. See Fig.45 for details. The interface ports for the equipmentmanagement are the following:

- LAN Ethernet 10BaseT/10Base2 or AUI

- USB port for 1+0 version

- RS232 asynchronous used for SCT/LCT connection

- RS232 asynchronous used for connection to further NEs

- EOC embedded within the PDH radio frame for connection to the remote NEs

- EOC embedded within the 2 Mbit/s tributary G.704 frame.

• Log–in: the main controller manages the equipment or network login/logout by setting and thencontrolling the user’s ID and relevant password.

• Database (MIB): validation and storing in a non–volatile memory of the equipment configurationparameters.

• Equipment configuration: distribution of the parameters stored in the MIB towards the peripheralµPs for their actuation in addition to the controls from user not stored in the MIB (i.e. loops, manualforcing etc...).

• Alarm monitoring: acquisition, filtering and correlation of the alarms gathered from slaved µPs. Lo-cal logger and alarm sending to the connected managers: SCT/LCT – NMS5UX. Management of thealarm signalling on the LIM front panel.

52 ALS - MN.00183.E - 003

• Performances: PM management as per Recc. G.828.

• Download: the main controller is equipped with two flash memory banks containing the running pro-gram (active bank) and the stand–by program (inactive bank). This permits to download a new soft-ware release to the inactive bank without distributing the traffic.Bank switch enables the new release to be used.Download activity is based on FTP protocol which downloads application programs, FPGA configu-ration, configuration files on main controller inactive bank or directly on the peripheral controllers.

Peripheral controllers

The peripheral controllers take place within the ODU and are slaved to main controller with the task of ac-tivating controls and alarm reporting of dedicated functionality.

8.1.4.3 Supervision ports

The equipment management is made by SCT/LCT program through the supervision ports.

The following are made available:

• LCT/RS232 interface ports using PPP protocol and baud rate speed up to 57600

• LAN interface using IP or IPoverOSI protocols

• EOC (Embedded Overhead Channel) using a 64 kbit/s slot of the radio frame to broadcast the su-pervision messages towards the remote terminals. The protocol used is IP or IPoverOSI.

8.2 IDU LOOPS

To control the IDU correct operation a set of local and remote loops are made available. The commandsare forwarded by the LCT/SCT program. Loop block diagram is shown by Fig.46.

8.2.1 Tributary loop

Tributary local loop

Each input tributary is routed directly to the trib. output upon receiving the command from the LCT. TheTx line transmission is still on.

Tributary remote loop

Each tributary directed towards the Rx output line is routed back to the Tx line. The Rx line is still on.

8.2.2 Baseband unit loop

This kind of loop is only local and is activated at BI/BE level. The Tx line is still on.

ALS - MN.00183.E - 003 53

8.2.3 IDU loop

This kind of loop permits to check the full IDU operation. When activated, the modulator output is connect-ed to demodulator input. The loop is assured by converting the frequency of the modulator from 330 MHzto 140 MHz.

9 DESCRIPTION OF THE MODULAR IDU WITH LIM ETHERNET (2 MBIT/S TRIBUTARIES + ETHERNET TRAFFIC)

Description that follows covers indoor unit with Ethernet ports, 1+0/1+1 Modular version. Paragraph 9.1.1LIM Ethernet: 2 Mbit/s tributaries deals with 2 Mbit/s signals and paragraph 9.1.3 LIM Ethernet: Ethernettraffic deals with Ethernet traffic treatment.

LIM Ethernet contains all the circuits of LIM with 2 Mbit/s interfaces plus some specific circuits for Ethernetinterface.

9.1 1+0/1+1 MODULAR IDU

Description that follows is referring to LIM/CONTROLLER/RIM modules contained into IDU.

9.1.1 LIM Ethernet: 2 Mbit/s tributaries

The LIM Ethernet performs the following operations:



• processing in digital form of the baseband part of the QAM modulator (the IF part of the QAM mod-ulator takes place within the RIM

• duplication of the digital processed signal to supply two RIMs in 1+1 versions. In the full duplicatedversion the changeover occurs at tributary level

• concatenation of 2 Mbit/s streams

• connection between a local LAN port and a remote LAN port.


9.1.2 Circuit description

Tx side

The 2/34 Mbit/s input signal is code converted from HDB3 to NRZ format before being multiplexed. Themultiplexing scheme depends on the number and the bit rate of the input tributaries.

In the following are described different multiplations:

64 ALS - MN.00183.E - 003

• 2/34 Mbit/s single tributary multiplexing. The mux performs stuffing operation and generates a pro-prietary frame to be sent to the Bit Insertion. Opposite operation occurs at the Rx side.

• 2x2 Mbit/s multiplexing. The mux performs stuffing operation on each single tributary and gener-ates a proprietary frame embedding the two tributaries to be sent to the Bit Insertion. Oppositeoperation occurs at the Rx side.

• 4x2 Mbit/s multiplexing. The mux aggregates the four 2 Mbit/s tributaries generating a 8448 kbit/s frame as per Recc. G.742. The multiplexed signal is then sent to the Bit Insertion. Opposite oper-ation occurs at the Rx side.

• 8x2 Mbit/s multiplexing. The eight 2 Mbit/s tributaries are grouped in two 4x2 Mbit/s groups eachof one generating a G742 frame structure at 8448 kbit/s to be sent to the next Bit Insertion. Oppo-site operation occurs at the Rx side.

• 16x2 Mbit/s multiplexing. The sixteen 2 Mbit/s tributaries are grouped in four 4x2 Mbit/s groupseach of one generating a G.742 frame structure at 8448 kbit/s. A further multiplexing of theachieved four 8448 kbit/s streams will generate a frame structure at 34368 kbit/s as per Recc.G.751. This latter is to be sent to the Bit Insertion.The 2 Mbit/s wayside undergoes stuffing processbefore being sent to the Bit Insertion. Opposite operation occurs at the Rx side.

• 32x2 Mbit/s multiplexing. This version consisted of two multiplexers of 16x2 Mbit/s signals. Each ofone will generate a 34368 kbit/s frame structure as per Recc. G.751.The two signals are sent to the Bit Insertion within the LIM for aggregation and stuffing process.The 2 Mbit/s wayside undergoes stuffing process before being sent to the B.I.Opposite operation occurs at the Rx side.

In addition to the tributary mux, an additional service mux is provided for aggregation of various servicesignals interfaced by Controller module.

The multiplexed tributary and service signals are then sent to the B.I. for aggregate frame generation oc-curring at the following bit rate depending on various versions implemented:

Tab.11 - Aggregate frame







The LIM also includes the processing in digital form of the modulating signal to be sent to the mixers ofthe QAM modulator within the RIM.

• clock recovery











The changeover is error free and the system has built in capabilities of minimising the passed errors duringthe detection time, such as the early warning criteria. The hitless switching facility provides automatic syn-chronisation of the two incoming streams up to a dynamic difference of ± 7 bits; additionally, the switchingunit is also capable of compensating static delays between the two incoming streams of up to ±7 bits. Atthe output of the Rx switch the Bit Extraction separates the main signal from the services and then, aftera proper demultiplexing process as previously described, sends them to the output interface lines.

9.1.3 LIM Ethernet: Ethernet traffic

Two versions of LIM Ethernet are available. They only differs for interface number:

• LIM Ethernet 4x2 Mbit/s + 3x10/100BaseT

• LIM Ethernet 16x2 Mbit/s + 4x10/100BaseT

In the following Ethernet interface circuits are described.

For the description of all the other circuits relative to 2 Mbit/s interface and the structure of LIM pleaserefer to previous paragraph. LIM Ethernet is equipped with the following interfaces:

• electrical interface Ethernet 10/100 BaseT IEEE 802.3

• from 0 to 4x2 Mbit/s (E1) interface

• total capacity from 2 to 64 Mbit/s or 105 Mbit/s

Most important functions of LIM Ethernet are:

• concatenation of Ethernet traffic in 2 Mbit/s tributaries and relevant multiplation

• LAPS Link Access Procedure SDH (ITU X.86) for concatenated 2 Mbit/s

• switch between a local LAN port and the radio LAN port

• MAC switching

• MAC address learning

• MAC address aging

• Ethernet interface with autonegotiation 10/100, full duplex, half duplex

- Ethernet interface with Flow Control, Back Pressure, MDI/MDX crossover

• network segmentation into the switch

• virtual LAN as per IEEE 802.1q (anyone from 0 to 4095 VID for a maximum of 64 memory location)(see Fig.52)

• layer 2 QoS, priority management as per IEEE 802.1p (see Fig.52)

• layer 3 ToS/DSCP (see Fig.54 and Fig.55)

• packet forwarding

A block diagram of LIM Ethernet module can be found into Fig.51.

Into LIM Ethernet there is a “switch” with 3 external ports and 1internal ports. External ports are electricalEthernet 10/100BaseT interfaces placed on the front panel. Internal port is connected to radio side stream.

Ethernet traffic coming from external ports goes to internal port radio side. The radio side port is connectedto one or two streams group of concatenated 2 Mbit/s. One stream for capacity up to 16x2 Mbit/s and twostreams for capacity of 12 – 16 2 Mbit/s streams, plus other 16x2 Mbit/s streams in case of maximumcapacity.

In Tx side Ethernet traffic is packet into a protocol called LAPS similar to HDLC. The resulting stream isdivided into the used number of 2 Mbit/s streams. The 2 Mbit/s streams are then multiplexed, like intostandard LIM, together with 2 Mbit/s arriving from front panel, the resulting stream goes to the modulator,see Fig.51.

In Rx the stream arriving from the demodulator is divided into the 2 Mbit/s streams, like into standard LIM,then the 2 Mbit/s not used into the front panel 2 Mbit/s are concatenated and sent to Ethernet circuits.Resulting stream, after LAPS protocol control, is sent to switch internal port.

9.1.3.1 2 Mbit/s tributaries

LIM Ethernet module uses the 16x2 Mbit/s mode of AL radio link. Tributary channels at 2 Mbit/s (E1) areconnected to 8 coaxial connectors 1.0/2.3 into front panel. 2 Mbit/s streams are multiplexed as into stand-ard LIM.

From 0 to 16 2 Mbit/s tributaries can be selected to be used via SCT/LCT program, all the other available2 Mbit/s are sent to switch internal port.

ALS - MN.00183.E - 003 67

For 100 Mbit/s version can be selected up to 2 tributaries, position number 3 and 4 in tributary connectorsare available for wayside connection (2 Mbit/s each).

9.1.3.2 Electrical Ethernet interface

The electrical Ethernet/Fast Ethernet interfaces are type IEEE 802.3 10/100BaseT with RJ45 connector. Forinput or output signals at RJ45 please refer to chapter 19 MODULAR IDU USER CONNECTIONS. Cable canbe UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair) Category 5.

Standard coding:

• Ethernet 10 Mbit/s: Manchester

• Fast Ethernet 100 Mbit/s: MLT–3 ternary

EMC/EMI protection:

• input and output pins are galvanically isolated through a transformer

• to reduce EMI every pin at RJ45 connector is terminated even if not used

• two signal lines are equipped with low capacity secondary protection to sustain residuals of possibleelectrostatic discharges (ESD).With LCT/SCT program it is possible to activate autonegotiation (speed/duplex/flow control) on 10/100BaseT interface.

9.1.3.3 Front panel LEDs

On FEM front panel there are a total of 6 Leds. There are 2 Leds for any Ethernet interface:

• DUPLEX: colour green, On = full duplex, OFF = half duplex

• LINK/ACT: colour green, ON = link up without activity, OFF = link down, BLINKING = link with ac-tivity on Rx and Tx.

9.1.3.4 Switch function

A radio link AL equipped with a LIM/Ethernet module can operate like a switch between two or more sep-arated LANs with the following advantages:

• to connect two separated LANs at a distance even greater than the maximum limits of 2.5 km (forEthernet)

• to connect two LANs via radio within a complex digital network

• to keep separated the traffic into two LANs towards MAC filtering to get a total traffic greater thantraffic in a single LAN.

The switch realized into LIM/Ethernet module is transparent (IEEE 802.1d and 802.q) into the same Vlandescribed by VLAN Configuration Table. It works at data link level, Layer 2 of OSI pile, and leave untouchedLayer 3 and it takes care to send traffic from a local LAN to another (Local or Remote). Routing is only onthe basic of Level 2 addresses, sublevel MAC.

The operation is the following:

• when a LAN interface receives a MAC frame, on the basis of destination address, it decides whichLAN to send it

• if destination address is on originating LAN the frame is discarded

• if destination address is a known address (towards address learning procedure) and is present intolocal address table the frame is sent only on destination LAN (MAC switching)

• otherwise the frame is sent to all ports with the same VLAN ID (flooding).

68 ALS - MN.00183.E - 003

The switch is very different from a Hub, which copies slavishly everything that receives from a line on allthe others. The switch, in fact, acquires a frame, analyses it, reconstruct it and routes it and compensatesalso the different speeds of the interfaces, therefore an input can be at 100 Mbit/s and output at 10 Mbit/s.

The mechanism is the following:

• from the moment of its activation, the switch examines all the frames that arrive it from differentLANs, and on these basis it builds its routing tables progressively.In fact, every received frame allows to know on what LAN the sending station is located (MAC ad-dress learning).

• every frame that arrives to the switch is rebroadcasted:

- if the switch has the destination address into the routing table, sends the frame only into thecorresponding LAN

- otherwise the frame is sent to all the LANs except the originating (flooding)

- as soon as the swicth increases its knowledge of different machines, the retransmission becomesmore and more selective (and therefore more efficient)

• the routing tables are updated every some minutes (programmable), removing addresses not alivein the last period (so, if a machine is moved, within a few minute it is addressed correctly) (MACaddress aging).

The whole process is restricted to the ports which are members of the same Vlan as described into VlanConfiguration Table.

9.1.3.5 Ethernet Full Duplex function

The first realizations of the Ethernet network were on coaxial cable with the 10Base5 standard.

According to this standard Ethernet interfaces (e.g. PC) are connected to the coaxial cable in parallel andare normally in receiving mode. Only one PC, at a certain time, transmits on the cable, the others are re-ceiving, so this is half duplex mode, and only one PC uses the received message.

Then the coaxial cable was progressively replaced by the pairs cable Unshielded Twisted Pair (UTP) as per10BaseT standard. Normally there are four pairs into UTP Cat5 cable but two pairs are used with 10BaseT,one for Tx one for Rx. Into 10Base5 and 10BaseT standards, network protocols are the same the differencelays into the electrical interface. UTP cable is connected point to point between a hub and a Ethernet in-terface. Network structure is a star where the server is connected to a hub and from this a UTP cable islaid down for each Ethernet interface starts.

The further step is to replace the hub with a more powerful equipment, e.g. a switch. In this case it ispossible to activate transmission on both pairs at the same time, on one twisted pair for one direction, onthe other pair for opposite direction. Thus we obtain full duplex transmission on UTP.

Activating full duplex transmission it is possible to obtain a theoretical increase of performance of nearly100%. Full duplex mode can be activated into 10/100BaseT interfaces manually or with autonegotiation100BaseFx operates always into full duplex mode.

9.1.3.6 Link Loss Forwarding

Link Loss Forwarding (LLF) is an alarm status of ethernet interface.

LLF can be enabled or disabled. If LLF is enabled an US radio alarm condition will generate the alarm statusof Ethernet interface blocking any transmission to it. LLF can be enabled for each ports at front panel. WithLLF enabled the equipment connected (routers, switches so on) can be notified that radio link is not avail-able and can temporarily reroute the traffic.

9.1.3.7 MDI/MDIX cross–over

The Ethernet electrical interface into FEM module can be defined by SCT program as MDI or MDIX to cross–over between pairs so that external cross–over cable is not required.

9.1.3.8 VLAN functionality

LIM Ethernet module works with IEEE 802.1q and 802.1p tag for VLANs and QoS see Fig.52.

The virtual LAN (VLAN) are logical separated subnets so that all the stations, into VLAN, seem to be intothe same physical LAN segment even if they are geographically separated.

The VLAN are used to separate traffic on the same physical LAN too. Station operating on the same physicalLAN but on different VLAN work in separated mode thus they do not share broadcast and multicast mes-sages. This results in a reduction of broadcast generated traffic and above all we get more security thanksto network separation.

Tag position and structure are shown into Fig.52.

Tag is made up with:

• a fixed word of 2 bytes

• 3 bits for priority according 802.1p

• 1 fixed bit

• 12 bits VLAN identifier (VLAN ID) according 802.1q.

Switch crossconnections are based on Vlan Configuration Table where input and output ports or only outputports should be defined for any used VID.

Vlan Configuration Table has 64 position for Vlan ID range from 1 to 4095.

9.1.3.9 Switch organized by port

The switch can be organized on port basis treating both Tagged and Untagged packets in the same way.

For each input port it is possible to define where to route the incoming traffic; one or more of the otherports can be Enabled to exit the incoming traffic. These types of connection are monodirectional. For adibirectional connection between a generic Lan A and Lan B it is necessary to set the connection from LanA to Lan B and from Lan B to Lan A.

LIM Ethernet has external ports and one internal port, radio side. The internal switch can connect two ormore ports together.

Then MAC address bridging rules will be applied to this packet. It is possible to select that a packet followsthe description of Vlan Configuration Table for its Vlan ID.

Another selection is to follow only Vlan Configuration Table.

Packets can exit from a port as Unmodified or all Tagged either all Untagged. Unteggad packets will takedefault tags.

For output operations there are 3 selections:

• unmodified: tagged packets keep their tag. Untagged packets remain untagged

• tagged: all the packets will exit tagged, tagged packets keep their tag, untagged packets take De-fault VID of incoming port.

• untagged: all the packets will exit untagged.

9.1.3.10 Switch organized by VLAN ID

Vlan Configuration Table

Vlan Configuration Table defines a list of Vlan ID, For any Vlan ID some ports are members of Vlan othersare not members. Ports members of a Vlan are allowed to receive and send packets with that Vlan. Switchdinamically assigns packets to the output port according their VLAN ID.

Packets aren’t sent out to that port unless they belong to one of the Vlan of which the port is a member.

70 ALS - MN.00183.E - 003

The ports, from which the packet can be sent, are defined in the VLAN Table. The VLAN of incoming packetis filtered only if the parameter “Ingress Filtering Check” is set as “Secure”.

After having filtered the ports from which packet can go out according to VALN Table, the control of packetand port Vlan membership MAC address bridging rules will be applied to this packet.

Ingress Filtering Check

This is a process to check an incoming packet to compare its Valn ID to input port’s Vlan membership. WithIngress Filtering Check it is possible to permit only to tagged packets to enter the switch. If the port is notmember of the Vlan n. XX all the incoming packets with Vlan ID XX will be dropped.

There are 3 option into Ingress Filtering Check to manage incoming packets:

• Disable: all Tagged and Untagged packets can transit into the switch following setting of switch or-ganized by port.

• Fallback: Incoming packets without TAG 802.1q follow the rules of switch organized by port, Taggedframes with Vlan ID described into the Vlan Configuration Table follow the rules of the table, Taggedframes with Vlan ID not described into the Vlan Configuration Table follow the rules of switch or-ganized by port.

• Secure: Incoming packets without TAG 802.1q cannot enter the switch, Tagged frames with VlanID described into the Vlan Configuration Table follow the rules of the table, Tagged frames with VlanID not described into the Vlan Configuration Table cannot enter the switch.

Operations at the input. At the input port the packet is received and a switching decision must be made.The switch analyses the Vlan ID (if present) and decides whether and where to forward the frame. If thereceived packet is untagged, the switch sends the packet to the port specified into incoming port “Lan perport” settings. If the packet is tagged the switch check the other destination ports to find at least one withthe same Vlan ID and put the packet into output port queue. If the Vlan ID is not listed into Vlan Config-uration Table the switch sends the packet to the port specified into incoming port “Lan per port” settings.Then MAC address bridging rules will be applied to this packet.

Operations at the output. For each output port there are the following selections for outgoing packets.

• Disable output port

• Enable unchanged: tagged packets keep their tag. Untagged packets remain untagged.

• Enable tagged: all the packets will exit tagged with Vlan ID specified into Vlan Configuration Table,tagged packets keep their tag, untagged packets take Default VID of incoming port.

• Untagged: all the packets will exit untagged.

9.1.3.11 Layer 2, Priority function, QoS, 802.1p

Some services as voice overIP and videoconference have some time limits to work properly. A solution isto increase the priority of time sensitive packets. In this case random crowding coming from other servicesaffects the delay of prioritized packets a lot less.Into LIM Ethernet module different priority of incoming packets is managed using Tag defined into IEEE802.1p (see Fig.52).Every switch output port holds 4 output queues: queue 4 has highest priority, queue 0 has the lowest pri-ority (see Fig.53).

Priority can be organized by incoming port or by incoming priority tag:

• Priority by incoming port. For Untagged packets at each input ports it is decided to send the packetsto one of the 4 queues of output ports defining which is the Default Priority Queue: Queue = 0, 1,2, 3. For Tagged packets it is necessary to Disable Priority so they will go in the same queue ofUntagged packets.

• Priority by incoming priority. For tagged packets for each priority tag (3 bits = for 7 priority levels)it is possible to define where to send the packets, into Queue from 0 to 3. Priority must be enableon 802.1p mode only or IpToS mode only (see next paragraph) or first check 802.1p mode andIpToS mode either first check IpToS mode only (see next paragraph) or first check 802.1p modeand IpToS mode either first check IpToS mode and then 808.1q. For untagged packets the priorityis defined only by incoming port..

ALS - MN.00183.E - 003 71

• Outgoing packet policy at output ports can be WFQ (Wait Fair Queue) with fixed proportional outputpolicy (8 packets from Queue 3, 4 from Queue 2, 4 from Queue 1, 1 from Queue 0) or “Strict Pri-ority” that means that a queue completely empties before processing the next one.

9.1.3.12 Layer 3, Priority function, QoS, IP–V4 ToS (DSCP)

Only for IP packets it is possible to use incoming Layer 3 ToS (see Fig.54) to prioritize incoming packets.The 8 bits available can be read as 7 bits of ToS or 6 bits of DSCP as shown in Fig.55.

According priority defined into ToS/DSCP the packet is sent into high priority queue low priority queue ofoutput ports.

With SCT/LCT program it is possible to select a different output queue for any ToS/DSCP priority level ateach input port.

The 2 Mbit/s tributary interface is 75 Ohm or 120 Ohm. Both interfaces are present into the front panelconnectors the user can select the interface to use, preparing in the correct way the relevant cabling.

12.7 MATRIX STM1+16E1 (1RU and 2RU)

Matrix module provides 16x2 Mbit/s interfaces and one SDH STM1 port. STM1 port is protected by twoSTM1 interfaces that can be available electrical or optical (different 2 plug-in modules).

STM1 is terminated and the contained E1 streams are sent to switch matrix, where E1 streams can be re-directed towards radio link, towards 2 Mbit/s interface or remapped into STM-1, or by means of NBUS to-wards other IDUs equipped with Matrix. Modular IDU Plus is operating in MST mode and has a completeSETS synchronisation circuit with input and output synchronisation signals.

With drop-insert configuration (only into 2RU, see Fig.58) it is possible to manage up to 4 directions radio(full capacity) with the possibility to drop-insert freely the 2 Mbit/s streams arriving from the 4 directionsand from front panel according the capacity of the switch matrix (32E1).

For example with 32E1 the maximum drop-insert possibilities is 32 tributaries but total capacity is limitedby total capacity of 4 directions. If total capacity of 4 directions is less then 32E1 that is the drop-insertlimit.

Maximum capacity arriving from the 4 radios is with 4 link at 53E1 for a total of 212 E1. For any configu-ration the switch matrix is no blocking. A repeater can be done without activating local E1 ports.

A node can be made up of up to 3 subracks of 2RU so that we can have up to 12 maximum independentradio directions.

On the front panel of the STM1+16E1 matrix there are two “NBUS” ports (1 and 2) which must be con-nected to other one or two 2RU subracks as in Fig.59 and Fig.60.

The connection among the subracks are made by cables of CAT7 quality, SIAE code F03471 length 75 cm,to insert into the NBUS connectors (1 and 2) on the front panel.

Each subrack must be defined as NodeA, NodeB or NodeC. The cables among the NBUS must be connectedonly as in Fig.59 and Fig.60.

NBUS can operate in Protected modality or in Not Protected modality. Each NBUS carries 126 E1’s. In caseof Not Protected modality, all the 126 E1’s of the NBUS are used to connect a subrack to the other for atotal amount of 252 E1 connections available on the NBUS.

In case of Protected modality, the unused connections, for example between node A (NBUS1) and node B(NBUS1) are used as protection of the connections between node A (NBUS1) and node B (NBUS1); forexample 63 E1’s are used between node A and node B and the other 63 E1’s are used as protection of theconnections between node A and node C, the connections used as protection pass from node B in pass-through modality without need of programming.

Warning: for the best operation of the protected modality, it is necessary to choose the shortest path aspreferential connection; for example, for the connections between A and B choose the connections betweenA and B as preferential; for the connection between A and C choose the connections between A and C aspreferential.

In case of protected modality, the system displays, by means of the SCT/LCT program in the cross-con-nection window, only the NBUS with 126 E1’s (subdivided in two parts for a better graphic display). Theunused E1 ports are automatically programmed as pass-through between NBUS1 and NBUS2 but theseconnections are not displayed in SCT/LCT.

In case of unprotected modality, the system displays, by means of the SCT/LCT program in the cross-con-nection window, the NBUS1 and NBUS2 buses each one with 126 E1’ (subdivided in two parts for a bettergraphic display).

The troubles in the connections between the NBUS buses are signalled by alarms.

In case of protected modality, if the cable carrying the traffic is broken, an alarm is issued on the relevantNBUS port, the equipment software switches the traffic on the other operating NBUS cable.

12.9.1 Expansion from 2 to 3 nodes

Suppose that the nodes A and B already exist and that you must add the node C. Disconnect the cablebetween NBUS2 node A and NBUS2 node B, the traffic is automatically switched to the other cable, if nec-essary.

By SCT/LCT, re-program the nodes A and B as nodes with 3 items.

By SCT/LCT, re-program the node C as nodeC, protected and define the node with 3 items.

88 ALS - MN.00183.E - 003

Connect the NBUS2 of the node A with NBUS1 of node C, connect the NBUS2 of the node B with NBUS2 ofthe node C as in Fig.59.

Program the interested cross-connections between node A and node C and between node B and node C;the unused connections are automatically assigned to the pass-through between node A and node B.

The same procedure can be used even if the added node is different from C.

12.9.2 Reduction from 3 to 2 nodes

Suppose that the nodes A, B and C already exist and that the node C must be removed.

Delete all the cross-connections between the node C and the node A and between the node C and the nodeB.

Remove the cables of the NBUS which go to node C.

Connect the node A NBUS2 to the node B NBUS2 as in Fig.60.

The same procedure can be used even if the deleted node is different from C.

In NMS5UX/LX the three nodes A, B, C are managed as a single equipment.

Fig.61 - Nodal - 12 max radio directions, max 6xstm-1, max 48E1 all disconnecting, no blocking

For each subrack of the node, a maximum of 4 radio streams of 53E1 arrive, for a total of 212E1. Eachsubrack can cross-connect, in no-locking mode, 212E1 (via radio) + 2x126E1 (via NBUS) + 16E1 (via SCSIconnector on the front side) + 2x63E1 (via STM-1) for a total of 606E1.

A node of 3 subracks with 2RU can cross-connect, in no-locking mode, up to 3x212E1 (via radio) + 3x16E1(via SCSI connector on the front side) + 6x63E1 (via STM1) for a total of 1062E1 (see Fig.61).

The Nodal equipment with SDH STM1 interface is a Regenerator Section Termination (RST) and a MultiplexSection Termination (MST) therefore it generates the STM-1 frame and has an internal synchronization cir-cuit SETS. The synchronization of the Node is distributed on the NBUS.

The SETS circuit can be seen as a single circuit which provides to the synchronization of the three subracks.

The SETS circuit can be disabled if only PDH interfaces are present in the node

For each Nodal subrack, the STM-1 interface can be duplicated (1+1 MSP) for the possible protection ofthe connection via cable.

12.10 DYNAMIC MODULATION

During the period of bad propagation, the system changes modulation to increase the system gain keepingconstant the transmitted band, decreasing the transmitted capacity and increasing the availability of thesystem for the privileged traffic.

With the dynamic modulation, about the half of the traffic is saved, without the dynamic modulation all thetraffic would be lost at the reaching of the BER threshold of 10-3.

The modulation switches from 32QAM to 4QAM or to 16QAM to 4QAM as in Tab.14.

Tab.14 - Capacity change

The reduction of the traffic capacity is communicated to NMS by means of the Reduced Capacity Alarm.

12.10.1 Capacity reduction

Conditions for the request of modulation change from 32/16QAM to 4QAM by the receiver with lower qual-ity (B):

1 the PTx power of the transmitter A towards B has reached the maximum value with ATPC active andMax PTx value set to the maximum value

2 the PRx power at the receiver B is lower than the ATPC Low Thresholds and then more power isrequired to the transmitter

3 BER at the receiver B is lowest than 10-9.

For the restore of the modulation from 4QAM to 16/32QAM, the following conditions are necessary on bothsides:

1 the PTx power at 4QAM is equal to the maximum power possible for the modulation 16/32QAM

2 the ATPC circuit is not requiring the increase of the Tx power of the remote transmitter

3 no error is occurred in the last seconds (default: 10 seconds).

Modulation 16/32QAM from Modulation 4QAM to

4x2 @ 16QAM no dynamic modulation

5x2 @ 16QAM no dynamic modulation

8x2 @ 16QAM 4x2 @ 4QAM

10x2 @ 16QAM 5x2 @ 4QAM

16x2 @ 16QAM 8x2 @ 4QAM

21x2 @ 16QAM 10x2 @ 4QAM

32x2 @ 16QAM 16x2 @ 4QAM

42x2 @ 16QAM 21x2 @ 4QAM

53x2 @ 32QAM 21x2 @ 4QAM

ALS - MN.00183.E - 003 91

Note: If maximum PTx at 4QAM is 20dBm and the maximum PTx at 16QAM is 15dBm then the differenceis 5dB the PTx Boost value can be from 0 to 5dB. If the ATPC values are not correct, the dynamic modu-lation is not activated.

The Performance Monitoring are reported as 16QAM. The AIS on the tributaries is not available.

The Upgrade of equipment already installed can be executed by means of the simple download from thesupervision network.

12.10.2 Setting with SCT/LCT

A green light signal shows that the dynamic modulation is active, the orange light signal signals that thereduction of modulation is active: in this case the Reduced Capacity Alarm is active.

Warning: no configuration change must be made when the Dynamic Modulation is active. In detail, if a loopmust be executed, first deactivate the Dynamic Modulation.

PTx Boost: increase of PTx power with reduced modulation, default 5Db Receiving Hysteresis: number ofdB from the Prx level with BER 10-9, default 2dB.

Atpc Hysteresis for recovering: hysteresis of Atpc from the restore of 16QAM, default 0dB.

Recovering timeout: seconds with PRx level stable before the restore of the 16QAM modulation, default10sec.

Tx power Overboost: increase of the Tx power of 3dB with 16QAM modulation. Enable only if allowed bythe laws of Your country.

12.11 LIM

The LIM performs the following operations:



• processing in digital form of the baseband part of the QAM modulator (the IF part of the QAM mod-ulator takes place within the RIM)

• duplication of the digital processed signal to supply two RIMs in 1+1 versions. In the full duplicatedversion the changeover occurs at tributary level.


12.12 CIRCUIT DESCRIPTION

Tx side

Refer to Fig.62.

The 2 Mbit/s input signal is code converted from HDB3 to NRZ format before being multiplexed. The mul-tiplexing scheme depends on the number and the bit rate of the input tributaries.

In addition to the tributary mux, an additional service mux is provided for aggregation of various servicesignals interfaced by Equipment Controller module.

92 ALS - MN.00183.E - 003

The multiplexed tributary and service signals are then sent to the B.I. for aggregate frame generation oc-curring at the bit rate depending on various versions implemented.







All the synch. signals to perform multiplexing (demultiplexing) and BI (BE) process are achieved from a x0at 48 MHz

The LIM also includes the processing in digital form (see Fig.62) of the modulating signal to be sent to themixers of the QAM modulator within the RIM.





Rx side

Refer to Fig.63.


• clock recovery











The changeover is hitless and the system has built in capabilities of minimising the passed errors duringthe detection time, such as the early warning criteria. The hitless switching facility provides automatic syn-chronisation of the two incoming streams up to a dynamic difference of ± 7 bits; additionally, the switchingunit is also capable of compensating static delays between the two incoming streams of up to ±7 bits. Atthe output of the Rx switch the Bit Extraction separates the main signal from the services and then, aftera proper demultiplexing process as previously described, sends them to the output interface lines.

12.13 RIM

Refer to Fig.64.




• power supply


There are two types of RIM according to modulation capability:

• 4QAM/16QAM or

• 4QAM/16QAM/32QAM

Inside the RIM, behind the front panel, the is a fuse for protection to whole IDU. It is a soldering type fuse.

ALS - MN.00183.E - 003 95



12.14.1 Service signals

The Equipment Controller offers an electrical interface to the following three service channel options:



• 2 Mbit/s wayside G.703 (not available in no-hierarchical configurations).


12.14.2 Equipment software



Main controller





- RS232 asynchronous used for SCT/LCT connection (if USB connector is not used) or with otherNE








• Download: the main controller is equipped with two flash memory banks containing the running pro-gram (active bank) and the stand–by program (inactive bank). This permits to download a new soft-ware release to the inactive bank without distributing the traffic.Bank switch enables the new release to be used.

96 ALS - MN.00183.E - 003

Download activity is based on FTP protocol which downloads application programs, FPGA configu-ration, configuration files on main controller inactive bank or directly on the peripheral controllers.



12.14.3 Supervision ports



• LCT (USB) and RS232 interface with PPP protocol

• LAN interface using IP or IPoverOSI protocols; two LAN interfaces are connected with a “all-pass”switch

ALS - MN.00183.E - 003 105

14.3 IDU CHARACTERISTICS

14.3.1 Management of tributaries

A 2 Mbit/s tributary can be managed by cross connection matrix in different ways:

• Ring Protection – A tributary is inserted (transmitted) in radio aggregate frame towards both direc-tion and can be dropped (received) from one direction or from the other depending on cross con-nection and E1 switch criteria

• Pass through – IDU works as repeater, tributary coming from one direction is sent to the other

• Loop – E1 accessing the matrix from East side or West side can be looped back towards its origin.

14.3.2 Capacity

IDU max capacity depends on modulation used:

• 16QAM – max capacity is 32x2 Mbit/s with maximum 16 tributaries with protected connections(Drop/Insert). Lower capacity can be set.

• 4QAM – max capacity is 16x2 Mbit/s and in this configuration all tributaries can be set in DropInsertor in Pass through (in this last configuration the three sides of the matrix have the same capacity:16x2 Mbit/s). Lower capacity can be set.

System can work with one branch capacity different than the other.

14.3.3 E1 switching criteria

In network configuration where thus East/West repeater IDU is employed as a Ring Protection, where adirection protects the other on the opposite direction, the E1 drop can be managed through suitable E1switching criteria:

1 Manual forcing

2 2 Mbit/s G.704 alarms (AIS, OOF, OOMF, BER6) where:

- AIS: presence of AIS

- OOF: out of E1 frame

- OOMF: out of E1 multiframe

- BER6: BER = 10–6

3 Preferential.

14.4 CIRCUIT DESCRIPTION

Description that follows is referring to MATRIX/PROCESSOR/CONTROLLER/RIM module the IDU consists of.

106 ALS - MN.00183.E - 003

14.4.1 Matrix

Matrix module presents on front panel the 2 Mbit/s connectors and contains the sixteen relevant electricalinterface and the cross connection matrix.

The matrix allows connections of 2 Mbit/s streams with following capacities and directions:

• east side – 32x2 Mbit/s, subdivided from 1 to 16 one at a time and from 17 to 32 framed inside a34368 kbit aggregate

• west side – 32x2 Mbit/s, subdivided from 1 to 16 one at a time and from 17 to 32 framed inside a34368 kbit aggregate

• towards front panel – 16x2 Mbit/s 75 ohm.

Function performed by matrix module are the following:

• code conversion of 2 Mbit/s streams in input and output (for Drop/Insert operations)

• tributary transit between East and West

• tributary transit towards one or both directions, in position not involved in tributary transit

• tributary drop from East or West or from one of them using appropriate switching criteria.

Tributaries cross connected by matrix are sent and received to/from East and/or West processor module,depending on their direction and connection.

Hitless Rx switch between 2 Mbit/s streams, coming from East and West, can work with relative delay upto 7 ms.

14.4.2 Processor

Operations performed by processor module depend on selected capacity and modulation.

Tx side

• 32x2 Mbit/s (available in 16QAM only) – processor module receives from matrix 32 tributaries, thefirst sixteen one by one and the second sixteen inside a 34368 kbit/s aggregate. The first sixteentributaries, in MUX block, are grouped in a frame structure at 34368 kbit/s as per Recc. G751. Inthis way two aggregates at 34368 kbit/s are sent to the Bit Insertion. The 2 Mbit/s wayside under-goes stuffing process before being sent to the B.I.After B.I. signal at 77760 kbit/s is sent to modulator.

• 16x2 Mbit/s – Processor module receives from Matrix 16 tributaries. The sixteen tributaries aregrouped in a frame structure at 34368 kbit/s as per Recc. G751. In this way the aggregate at 34368kbit/s is sent to the Bit Insertion. The 2 Mbit/s wayside undergoes stuffing process before being sentto the B.I. After B.I. signal at 38880 kbit/s is sent to modulator.

• 8x2 Mbit/s – Processor module receives from matrix 8 tributaries. These are grouped in two 4x2Mbit/s groups generating a G.742 frame structure at 8448 kbit/s and sent to the Bit Insertion. AfterB.I. signal at 19440 kbit/s is sent to modulator.

• 4x2 Mbit/s – Processor module receives from matrix 4 tributaries. These are grouped in one 4x2Mbit/s group generating a G.742 frame structure at 8448 kbit/s and sent to the Bit Insertion. AfterB.I. signal at 9720 kbit/s is sent to modulator.

• 2x2 Mbit/s – Processor module receives from matrix 2 tributaries. These are grouped in a proprie-tary frame and sent to the Bit Insertion. After B.I. signal at 4860 kbit/s is sent to modulator.

An additional Service Mux/Demux is provided to aggregate various service signal interfaces by Controllermodule. Achieved stream is sent to BI/BE to obtain the aggregate frame (various bit rate depending oncapacity set) for block MOD/DEMOD.

This aggregate frame contains:

• main signal from MUX and from MATRIX

• aggregate signal from service MUX

ALS - MN.00183.E - 003 107

• EOC signal for supervision towards remote equipment

• Frame Alignment Word

• Bits dedicated to FEC.

Processor also includes digital process of modulating signal to be sent to the mixer of QAM modulator insideRIM. The digital process includes:



• generation of shaped modulating signal I and Q towards the RIM module.

Rx side

From connected RIM, Processor module receives I and Q analogue signals, converts them in digital formand performs:

• clock recovery



• bit decision


• parallel to serial conversion to recover aggregate signal.

Aggregate signal is sent to a frame alignment circuit and CRC analysis and after to error corrector block(FEC). Errors are properly counted to achieve:


• Radio performances.

HBER alarm is used to insert AIS in Rx signal.

Achieved signal is sent to Bit Ex circuit that, depending on capacity and modulation, performs in oppositeway the operations mentioned in Tx side.

16 OUTDOOR UNIT DESCRIPTION

16.1 GENERAL

The 1+0 ODU (refer to Fig.75 or to Fig.77) consists of a two shell aluminium mechanical structure, oneshell housing all the ODU circuits, the other forming the covering plate.

On the ODU are accessible:

• the “N” type connector for cable interfacing IDU and ODU

• the “BNC” connector for connection to a multimeter with the purpose to measure the received fieldstrength

• a ground bolt.

The 1+1 hot stand–by version (refer to Fig.76) consist of two 1+0 ODUs mechanically secured to a struc-ture housing the hybrid for the antenna connection.

ODU exists in two different versions, AL and AS. They differs about dimensions and output power.

AS ODU is also called Universal because it can work with ALS equipment (SDH).

16.2 TRANSMIT SECTION

Refer to block diagram shown in Fig.78.

The 330 MHz QAM modulated carrier from the cable interface (see chapter 16.4 CABLE INTERFACE) is for-warded to a mixer passing through a cable equalizer for cable loss compensation up to 40 dB at 330 MHz.The mixer and the following bandpass filter give rise to a second IF Tx carrier the frequency of which de-pends on the go/return frequency value. The mixer is of SHP type.

The IF Tx frequency is µP controlled. Same happens to Rx IF and RF local oscillators. This latter is commonto both Tx and Rx sides.

The IF carrier is converted to RF and then amplified making use of a MMIC circuit. The conversion mixer isSSB type with side band selection.

The power at the MMIC output can be manually attenuated by 40 dB, 1 dB step.

Total attenuation is 40 dB including the 20 dB attenuator that follows.

The automatic adjustment is performed making use of an ATPC (see paragraph 16.5 ATPC OPERATION fordetails). The regulated output power is kept constant against amplifier stage gain variation by a feedbackincluding the AGC.

Before reaching the antenna side the RF signal at the output of MMIC passes through the following circuits:

• a decoupler plus detector diode to measure the output power

• a circulator to protect the amplifier stages against possible circuit mismatch.

• a ON/OFF switch for 1+1 operation

• an RF bandpass filter for antenna coupling.

An RF coupler plus a detector and a shift oscillator made up the RF loop which is enabled upon receiving aµP control. The RF loop permits the Tx power to return back to receive side thus controlling the total localradio terminal performance.

ALS - MN.00183.E - 003 119

16.3 RECEIVE SECTION

The RF signal from the Rx bandpass filter is sent to a low noise amplifier that improves the receiver sen-sitivity. The following down–converter translates the RF frequency to approximately 765 MHz. The conver-sion mixer is SSB type. The sideband selection is given through a µP control.

A second down converter generates the 140 MHz IF carrier to be sent to the demodulator within the IDU.The level of the IF carrier is kept constant to –5 dBm thank to the IF amplifier stages, AGC controlled,distributed in the IF chain. In addition the AGC gives a measure of the receive RF level.

Between two amplifiers a bandpass filter assures the required selectivity to the receiver. The filter is SAWtype and the bandwidth depends on the transmitted capacity.

16.4 CABLE INTERFACE

The cable interface permits to interface the cable interconnecting IDU to ODU and viceversa.

It receives/transmits the following signals:

• 330 MHz (from IDU to ODU)

• 140 MHz (from ODU to IDU)

• 17.5 MHz (from IDU to ODU)

• 5.5 MHz (from ODU to IDU)

• remote power supply.

The 17.5 MHz and 5.5 MHz FSK modulated carriers, carry the telemetry channel. This latter consists of two388 kbit/s streams one from IDU to ODU with the information to manage the ODU (RF power, RF frequen-cy, capacity, etc...) while the other, from ODU to IDU, sends back to IDU measurements and alarms of theODU. The ODU management is made by a µP.

16.5 ATPC OPERATION

The ATPC regulates the RF output power of the local transmitter depending on the value of the RF level atthe remote terminal. This value has to be preset from the local terminal as threshold high and low. Thedifference between the two thresholds must be equal or higher than 3 dB.

As soon as the received level crosses the preset threshold level low (see Fig.81) due to the increase of thehop attenuation, a microP at the received side of the remote terminal sends back to the local terminal acontrol to increase the transmitted power. The maximum ATPC range is 40 dB.

If the hop attenuation decreases and the threshold high is crossed then the control sent by the microPcauses the output power to decrease.

16.6 1+1 Tx SYSTEM

The two ODUs are coupled to the antenna side via a balanced or unbalanced hybrid.

1+1 Tx switching occurs in the 1+1 hot stand–by 1 antenna or 2 antennas versions as shown in Fig.79 andFig.80.

120 ALS - MN.00183.E - 003

The transmitter switchover is electromechanical type and consists of two ON/OFF switches within the twoODUs that assure at least 40 dB insulation on the stand–by transmitter.

Transmit alarm priority is shown in Tab.18.

Tab.18 - Transmit alarm priority

16.7 POWER SUPPLY

The battery voltage is dropped from the cable interface and then sent to a DC/DC converter to generatethree stabilized output voltages to be distributed to the ODU circuitry:

• +3.5 V

• a voltage comprised between +6.2 V and +8.2 V to power MMIC amplifiers operating at differentfrequency bands

• a –12 V through an inverter circuit.

Each voltage is protected against overcurrent with automatic restart.

Protection against overvoltage occurs as soon as the output voltage raises more than 15% respect to thenominal voltage. The restart is automatic.

Section 4.LINE-UP

29 LINE–UP OF THE RADIO HOP

29.1 LINE–UP OF THE RADIO HOP

The line–up consists of the following steps:

• on site radio terminal installation (user connections and ODU installation as described in the rele-vant chapters)

• equipment switch–on

• equipment configuration (through PC software)

• antenna alignment for maximum received RF signal level

• network element configuration

• check measurements.

Equipment installation is described in Section 3. INSTALLATION.

29.1.1 Equipment configuration

In order to have the link working properly, in the local and remote equipment the same parameters haveto be set:

• system layout (1+0, 1+1 hot stand-by, 1+1 frequency diversity.....) (Equipment - General)

• capacity (Equipment - General)

• modulation (Equipment - General)

• link ID (Equipment - General)

• RF channel (Radio - Radio Branch)

246 ALS - MN.00183.E - 003

The software to run is relevant to the equipment to configure:

• LCT in case of AL, ALC AL Plus

• WEB LCT in case of ALC Plus.

Traffic (Baseband - Tributary)

Used tributaries must be enabled on local and on remote equipment.

Service channels (Service Channels)

Service channels setting must be the same on local and on remote equipment: different settings of notused service channels, between local and remote equipments, cut the operation of those service channelsproperly set also.

In the following chapters, all the configuration steps are explained using LCT that differs from WEB LCT ingraphical layout only.

29.1.2 Antenna alignment and received field measurement

Purpose of antenna alignment is to maximize the RF received signal level.

Proceed as follows:

• connect a multimeter to BNC connector on the ODU for AGC measurement

• adjust antenna pointing as soon as the maximum AGC voltage value is achieved.

The relationship between AGC voltage and received field is shown by Fig.165.

The received field level has a tolerance of ±4 dB in the full temperature range.

29.1.3 Network element configuration

A factory default address is assigned to each network element that must normally be reconfigurated onsite following the network administrator rules.

To the purpose it is required to connect the PC, where the SCT/LCT program has been installed, to thenetwork interfaces.

This has to be done via serial cable or Ethernet cable.

Warning: the checks that follow require a good knowledge of the program use.

The description of each menu and relevant windows are given by the program itself as help on line.

Run the program and perform the connection to equipment by choosing from menu “Option” the connec-tion made via serial cable.

Perform the login to the equipment by entering:

• Equipment IP address 3

• User ID (default: SYSTEM)

• Password: (default: siaemicr)

Proceed to program what above mentioned following this path:

3 If the connection is made via serial cable, the IP address is automatically achieved.

ALS - MN.00183.E - 003 247

• IP Address: select menu “Equipment” from the menu bar and then Communication Setup–>PortConfiguration. Enter the required port addresses in the available communication ports. Press ? fordetails.

• Routing Table and Default Gateway: select menu “Equipment” from the menu bar and then Com-munication Setup–>Routing table: enter the routes or default gateway if necessary. Press ? for de-tails.

Warning: the routing policy depends on the routing type: manual IP/OSPF/IS–IS. The relevantrouting rules must be normally given by network administrator.

• Remote Element Table: select menu “Tools” from menu bar and then Subnetwork ConfigurationWizard. Station name and remote element table must be assigned following description of the con-textual help on–line (?).

• Agent IP Address: select menu “Equipment” and then “Properties”. Assign the address in accord-ance to the address of the remote element you want to reach.

29.1.4 Radio checks

It is advisable to perform the following measurements to check the correct operation of the radio hop:

• transmitted power

• received power

• RF frequency

• BER measurement

All these checks make use of the SCT/LCT program.

• Transmitted power, received RF level, RF frequency

- run SCT/LCT program and then perform the connection to the equipment you want to check.

- make double click on the select equipment until main RADIO PDH–AL window is shown.

- on top of the window Tx/Rx power and frequency values are displayed. In case of Tx power andfrequency setup proceed to Branch 1/2 and Power/Frequencies submenus.

• BER measurement

30 LINE–UP OF LIM ETHERNET/2 MBIT/S

30.1 GENERAL

This paragraph deals with line–up of LIM Ethernet module with details of SCT/LCT program related only toEthernet application.

Assuming that the radio link is already in service, with correct frequency, output power and correct antennaalignment, the line up procedure for two different kinds of connection set up of a radio link AL, equippedwith LIM Ethernet/2 Mbit/s module, is hereafter described:

1 Local Lan–1 port to remote Lan–1 port connection Lam per port, see Fig.166

2 Local Lan–1 port to remote Lan–1 port connection with only VLANs

3 3 to 1 port connections, see Fig.179.

Settings here below are intended to be done both into local and remote radio equipment.

The software to be used depends on the equipment you have to configure.

• LCT for AL, ALC, AL Plus

• WEB LCT for ALC Plus.

In the following chapters all configuration steps are shown using LCT. LCT and WEB LCT only differs ingraphical interface.

30.2 LOCAL LAN–1 PORT TO REMOTE LAN–1 PORT TRANSPARENT CONNECTION LAN PER PORT

Settings for Untagged and Tagged Traffic

Fig.166 - Local Lan–1 port to remote Lan–1 port connection

The line–up of AL with LIM Ethernet is made with the help of SCT/LCT program.

Please refer to Fig.167. First selection is Ethernet throughput and modulation scheme, in this example weselect 16 Mbit/s and modulation 16QAM (max throughput and modulation scheme depend on terms of li-cence provided by Siae Microelettronica).

Select configuration 1+0 or 1+1 according system requirements. Inside LCT, select Tributary window (seeFig.168). If 2 Mbit/s tributaries are needed, inside the Tributary window it is possible to activate a 2 Mbit/

s input/output on the front panel. When the activation of required 2 Mbit/s tributaries is completed, all theothers 2 Mbit/s streams are automatically used for the Ethernet traffic. For instance with a 8x2 Mbit/s ca-pacity if we use two 2 Mbit/s the capacity assigned to Ethernet circuits is automatically set to 6x2 = 12Mbit/s full duplex.

Fig.167 - Selection of Ethernet Throughput

ALS - MN.00183.E - 003 251

Fig.168 - Tributary enable

See Fig.169 for General settings for the switch. All the used ports must be Enabled, so enable Lan–1 andInternal Port, see Fig.170.

The other ports should be disabled. The correct cable crossover arrangement must be selected too (seeFig.170). Enable LLF if needed only at the end of link line up.

For Untagged traffic, connections are done with Lan per port selections. Referring to Fig.171 incoming traf-fic at Lan–1 exits at Internal Port and into Fig.173 incoming traffic at Internal Port exits at lan–1 port. Thisconnection are done for all Untagged traffic and all Tagged packets with Vlan Id not described into VlanConfiguration Table.

If Vlan Configuration Table is blank all Tagged traffic follows the rules of Lan per port.

Possible selections of Ingress Filtering Check:

1 “Disable 802.1q”: no check of Virtual Lan tag is made and all packets follow Lan per port settings

2 “Fallback”: if Tagged packets have their Vlan Id into Vlan Configuration Table they follow the con-nection described into the table, otherwise they follow the Lan per port settings as Untagged pack-ets

3 “Secure”: no Untagged packet transits; only Tagged packets with Vlan Id listed into the table cantransit. For all pass configuration “Disable 802.1” should be selected. With Egress Mode as Unmodi-fied the outgoing packets at Lan–1 port exit Untagged or Tagged exactly as they were Untagged orTagged at the incoming port.

30.3 LOCAL LAN–1 PORT TO REMOTE LAN–1 PORT TRANSPARENT CONNECTION LAN PER PORT

Settings are done to transfer only Tagged traffic within some Vlans.

We want that Vlan 701, 702, 710 and 1, 2, 3 can pass into the radio link and all the other Tagged or Un-tagged packets should be blocked.

ALS - MN.00183.E - 003 255

The line up of AL with LIM Ethernet is made with the help of LCT/SCT program. Please refer to Fig.166.First selection is Ethernet throughput and modulation scheme, in this example we select 16 Mbit/s andmodulation 16QAM (max throughput and modulation scheme depends on terms of licence provided by SiaeMicroelettronica). Select configuration 1+0 or 1+1 according system requirements.

Inside LCT, select tributary window (see Fig.167). If 2 Mbit/s tributaries are needed, inside the tributarywindow it is possible to activate a 2 Mbit/s input/output on the front panel. When the activation of required2 Mbit/s tributaries is completed, all the others 2 Mbit/s streams are automatically used for the Ethernettraffic. for instance with a 16 Mbit/s capacity if we use two 2 Mbit/s the capacity assigned to ethernet cir-cuits is automatically set to 16–2x2 = 12 Mbit/s full duplex.

See Fig.168 for general settings for the switch. All the used ports must be enabled, so enable Lan–1 andInternal Port, see Fig.169. The other port should be disabled. The correct Cable crossover arrangementmust be selected too. Enable LLF if needed only at the end of link line up.

Vlan settings for Lan–1 and Internal Port should be like in Fig.175 with Ingress Filtering Check as “Secure”and Engress Mode as “Tagged”. With this setting only Tagged packets with Vlan ID listed into the Vlan Con-figuration Table can transit. All Untagged packets are blocked at the incoming port and outgoing Taggedpackets don’t change.

A packet with Vlan ID XX can enter into the switch only if Incoming Port (Ingress port) is a member of theVlan XX, same packet will exit only from ports (Engress Port) which are members of Vlan XX. Vlan mem-bership is described into Vlan Configuration Table. A port can be member of no one, one or more Vlans.See Fig.176 for Vlan Configuration Table settings for our example.

Fig.175 - Virtual Lan input and output settings at Lan–1 port

256 ALS - MN.00183.E - 003

Fig.176 - Vlan Configuration Table with some Vlans

Tagged incoming packet can be treated with FIFO policy or on the basis of their 802.1p priority tag andToS/DSCP value for IP packets. There are 4 queue at each output port. The decision about to which outputqueue to send a packet is defined into Ethernet switch window selections for 802.1p tag. Into Ethernetswitch window it is possible to select ToS/DSCP button to open window ToS/DSCP, in this window eachincoming ToS/DSCP value is associated with an output queue so it is possible to change the priority of theincoming packet.

When no info on priority is available, the packet is sent to Default Priority Queue using FIFO policy.

Into Lan–1 window select Priority (802.1q), into priority box there are some selections: with “Disable”switch doesn’t look at priority tag; with “802.1p” switch looks at Tag 802.1p only; with “IpToS” for IP pack-ets only switch looks to ToS/DSCP identifier (into IP frame) only; with “802.1p – IpToS” switch looks firstto 802.1p tag and secondly to ToS/DSCP, see Fig.178; with “IpToS–802.1p” switch looks first to ToS/DSCPand secondly to Tag 802.1p.

Note: with IpToS switch looks to IP packet and ToS/DSCP doesn’t matter if the packets are tagged with802.1p or not.

In this example incoming tagged are tagged and it is necessary to transfer the packets with no change sothey must exit from output ports tagged, see Fig.176 and Fig.177.

30.4 3 TO 1 PORT CONNECTIONS

Fig.179 - 3 to 1 port connections

In this example 3 local port must communicate with corresponding remote ports. All the ports share thesame radio channel but traffic originated and directed to Lan1 should be kept separated from traffic fromLan2 and Lan3 and viceversa.

Lan–1 to Lan–1 connection should transfer tagged packets with Vlan 1, 701, 760 and untagged packets.Unspecified tagged packets must be stopped. Lan–2 and Lan–3 have the same requirements. For all con-nections IP packets with high priority TOS should transferred at minimum delay.

30.5 3 TO 1 PORT CONNECTIONS, SETTINGS FOR UNTAGGED TRAF-FIC

The line–up of AL with LIM Ethernet is made with the help of LCT/SCT. Please refer to Fig.166.

First selection is Ethernet throughput and modulation scheme, in this example we select 16 Mbit/s andmodulation 16QAM (max throughput and modulation scheme depend on terms of licence provided by SiaeMicroelettronica). Select configuration 1+0 or 1+1 according system requirements.

Inside LCT, select Tributary window (see Fig.167).

If 2 Mbit/s tributaries are needed, inside the tributary window it is possible to activate a 2 Mbit/s input/output on the front panel. When the activation of required 2 Mbit/s tributaries is completed, all the others2 Mbit/s streams are automatically used for the Ethernet traffic. For instance with a 8x2 Mbit/s capacity ifwe use two 2 Mbit/s the capacity assigned to Ethernet circuits is automatically set to 6x2 = 12 Mbit/s fullduplex.

Vlan Configuration Table will be defined in order to group traffic from Lan–1, Lan–2, Lan–3 to Port1. All theused ports must be Enabled.

Untagged traffic transits only if the selection for Ingress Filtering Check is disabled at each input port anda separated Vlan for Untagged traffic is set up for each port. See Fig.168, Fig.169, Fig.178, Fig.179,Fig.180.

Each port of the switch must be associated with a different Default VLAN ID in order to maintain the trafficcoming from different separated LANs, Lan–1 with default VID 3301, Lan–2 with default VID 3302, Lan–3with default VID 3303, for Lan–1 see Fig.180, Fig.181 and Fig.183.

The correct Cable Crossover arrangement must be selected too.

Fig.180 - Input and output setting for VLANs at Lan–1 port

ALS - MN.00183.E - 003 259

Fig.181 - Output port properties for VLAN 3301

Fig.182 - Typology 3 to 1, Virtual Lan Configuration

With the above settings inside the VLAN configuration Table only Untagged traffic is forwarded accross thebridge.

The same settings should be done inside the remote equipment. The above example shows the Virtual LanConfiguration Table in case of a link carrying the traffic of 3 independent LAN’s connected to Lan–1, Lan–2, Lan–3, which is split at the remote end among the outgoing Lan–1, Lan–2, Lan–3 ports, while using acommon radio link.

To prioritize some IP packets with high ToS/DSCP value it is possible to open PToS/DSCP window from Eth-ernet switch window and select the values of ToS for which the packet is sent to high priority Queue, seeFig.183.

Default VID assigned byuser to each port

Vlan 3301, 3302, 3303 are allowed to exit at Port1 with tags (Tagged). Different default Tag’s allow to

keep separate the traffic from Lan1, Lan2 andLan3 exiting at Port 1. At the remote end the traffic

is split and forwarded from Port1 to Lan1, Lan 2 and Lan3 without Tag to preserve the original

format.

Fig.183 - Output Queue selection on the basis of TOS/DSCP priority

30.6 3 TO 1 PORT CONNECTIONS, SETTINGS FOR TAGGED AND UN-TAGGED TRAFFIC

If we want VLAN with Tag 701, 702 and 703 to transit between Lan–1 and Port–1 it is necessary to definePort 1 and Lan 1 as members of VLAN1, 701, 760 (see Fig.184 for VLAN 701 and do the same for VLAN1,760).

The VLAN Configuration Table will look like Fig.185.

For Lan–2 and Lan–3 we cannot use the same Vlan if we want to maintain traffic from Lan 1, 2, 3 separated.We must change the number of incoming Vlan for instance of 1, 701, 760 use 2001, 2701, 2760 for Lan–2 and 3001, 3701, 3760 for Lan–3. Connected equipment to Lan–2 port should be reprogrammed to useVlan 2001, 2701, 2760.

Connected equipment to Lan–3 port should be reprogrammed to use Vlan 3001, 3701, 3760.

To prioritize Ip packets with high ToS/DSCP value it is possible to open PToS/DSCP window from Ethernetswitch window and select the values of ToS for which the packet is sent to high priority Queue 3, seeFig.181. The same should be done inside the remote equipment.

30.7 3 TO 1 CONNECTIONS: EXAMPLES OF PRIORITY MANAGEMENT

Example 1: To assign to Lan–1 and Lan–3 low priority and to Lan–2 high priority, while wanting Taggedand Untagged to be treated in a fair manner on each queue do as follow: select Priority Disable for Lan–1,Lan–2 and Lan–3; select Default Priority Queue equal to Queue 0 for lan–1 and Lan–3 (see Fig.172). SelectDefault Priority Queue equal to Queue 3 for Lan–2 (as in Fig.186).

Outgoing Untagged packets will take priority tag defined into input port, in this case 0. Tagged frames keeptheir tag.

262 ALS - MN.00183.E - 003

Example 2: Wanting tagged frames to be treated according their actual priority and untagged packets withlow priority, all inputs should be configured as in Fig.187.

Layer 2 Priority assignment is not modified if inside the second folder of the Lan–X (1, 2, 3) configurationwindow Untagged Frame Egress Mode = Unmodified is selected as in Fig.188.

Fig.186 - Queue selection

Untagged packet arriving to Lan-2 are sent to output port Queues setting of this folder. In this example all incoming packets at LAN-2 are inserted into output

Queue 3 of output ports.Input priority: when Disable is not selected, Tagged frame are sent to queue

0,1,2,3 to port destination priority value; when Disabled is selected for this portswitch uses the Default Priority Queue for Tagged and Untagged frames, and

without really changing Tag into Incoming Tagged frames.

32.3 TRIBUTARY CONFIGURATION

The operations to enable the tributaries involved in the cross-connections with the matrix are:

• run the software LCT, open BaseBand, Tributaries and select the type of used tributary

• enable the E1 and/or STM-1 tributaries (transport of 63 E1 each) involved by the cross-connection.To route an E1 stream to remote equipment, a Tributary - Radio cross-connection must be created,the enabling of the stream itself is not sufficient.

• in case of STM-1 streams, configure the parameters VC4 and VC12 and the synchronization param-eters (LCT, Synchronisation)

32.4 Configuration of the Cross-connection matrix

The operations to configure a cross-connection are:

• run the software LCT, open Cross Connection, Matrix and press Configuration

• select the type of cross-connection:

- Tributary - Radio : Cross-connection between the tributaries available on the front side of theMatrix module (E1, STM-1, NBUS or NBUS1 and 2) and the tributaries available on the radioLink, 1A, 2A, 1B or 2B (it depends on the capacity set on the radio Link)

ALS - MN.00183.E - 003 273

- Tributary - Tributary : Cross-connection between the tributaries available on the front side ofthe Matrix module (E1, STM-1, NBUS or NBUS1 and 2)

32.4.1 Tributary - Radio Cross-connection

The operations to create and configure this cross-connection are:

• select the type of tributary to use on the front side of the Matrix module: the relevant E1 streamswill be displayed in the window together with the number of E1 streams relevant to the radio Link

• select which radio Link you wish to use in the cross-connection (up to four available)

• move the symbol of the E1 stream (the number corresponds to the physical position in the connec-tor of the Matrix module) by dragging and dropping from a type of tributary to the position to usein the radio frame, see Fig.198.

• the first create cross-connection is the main (colour blue); a second one regarding the same E1 trib-utary can be created to the radio Link B with the same modality. The second cross-connection willbe the reserve (colour pink) of the first one. The parameters, and the possible alarms, ruling theswitch between the two radio directions can be configured in the window which can be opened bya double click on the box relevant to the E1 tributary on matrix side, see Fig.199

• the tributaries in the radio frame (Link direction A or others) can be involved in a tributary looptowards the corresponding remote radio by means of a double click on the relevant box that pointsout the position in the frame, see Fig.200

• the tributaries on radio side can transit directly from a radio link to the other without need to passfrom the tributaries on matrix side: by means of drag'n'drop, a box relevant to an E1 on radio sideis moved from a Link to the other Link. The two involved Links must be selected in the fields 1stRadio and 2nd Radio. A pass-through (transit) cross-connection is so executed: see Fig.201

• to delete a cross-connection, move it to the trash

• to activate the configuration, press Apply and Confirm.

35 TROUBLESHOOTING

35.1 GENERAL

The AL equipment consists of the following replaceable parts:

• LIM

• RIM

• CONTROLLER

• ODU.

Purpose of the troubleshooting is to pinpoint the faulty part and replace it with spare.

Warning: the replacement of the faulty CONTROLLER module with spare causes the spare CONTROLLERto be re–programmed. To the purpose refer to chapter 26 INSTALLATION ONTO THE POLE OF THE ODUWITH INTEGRATED ANTENNA (KIT V32307, V32308, V32309) and 28 INSTALLATION ONTO THE POLE OFTHE 4 GHz ODU WITH SEPARATED ANTENNA (KIT V32323) for the relevant procedure.

35.2 TROUBLESHOOTING PROCEDURE

Troubleshooting starts as soon as one of the following alarm condition: IDU/ODU/REM is switched ON onthe IDU panel from (see Fig.215) or alarm messages are displayed by managers SCT/LCT.

Two methods are used to troubleshoot the cause of fault:

• loop facilities

• alarm message processing using the manager SCT/LCT

35.2.1 Loop facilities

The equipment is provided with different loops with the aid to locate the faulty equipment and then thefaulty module the equipment consists of.

Warning: the majority of loops causes the traffic to be lost.

The available loops are the following:

• local tributary loops: usually used to test the cables interfacing the equipment upstreams

• remote tributary loops: usually used to test the two direction link performance making use of anunused 2 Mbit/s signal.

• baseband loop: it permits to test the LIM circuits

• IDU loop: it permits to test the complete IDU

• RF loop: it permits to test the complete radio terminal

ALS - MN.00183.E - 003 291

35.2.2 Alarm messages processing

When an alarm condition occurs, the equipment generates a number of alarm messages that appear onthe SCT windows ie: log history area and equipment view current alarm.

Investigation on the alarm message meaning permits to troubleshoot the faulty module.

Alarm message organisation

The alarms (traps) are organized as alarm grouping relevant to a specific functions performed by the equip-ment.

The alarm grouping is available only in the view current alarm submenu.

What follows is the list of the alarm grouping:

• COMMON – alarms which are not related to a specific part of the equipment but relevant to the linkas EOC radio link alarm or link telemetry fail. If these alarms are ON the link is lost. Investigationmust be made on a possible bad propagation or equipment failure. See the condition of the othersalarm grouping.

• LIM – This grouping may generate alarms for the following causes:

- external fault: tributary loss signal

- LIM failure: i.e. multiplexer/demultiplexer failure or modulator/demodulator failure.Warning: The modulator/demodulator circuitry is spread into the LIM and RIM modules. Substi-tution method is the only way to pingpoint the faulty module

- alarm that can be propagated by RIM or ODU modules as baseband Rx alarm.The Baseband loop permits to discover if the cause of this alarm activation is external or internalto the LIM. If yes the module must be replaced.

• RIM – This grouping may generate alarms for the following causes:

- external fault: demodulator fail alarm and local ODU alarm are generated when the ODU be-comes faulty.

- RIM failure – power supply alarm along with cable short/open alarms or modulator/demodulatoralarms are activated.Warning: the modulator/demodulator circuitry is spread into the LIM and RIM modules. Substi-tution methods is the only way to pinpoint the faulty module.

• RT – This grouping may generate alarms for the following causes:

- external fault: Rx power low alarm is generated given by a bad propagation or by a faulty remoteterminal.

- ODU failure: PSU fail alarm or RF VCO alarm or RT IF alarm is activated. If this happens, replacethe ODU.

• UNIT – This grouping generates alarms when one of the units, the equipment consists of, is faultyor does not respond to the controller polling. Replace the faulty unit.

• CONTROLLER – There is not an alarm message relevant to a controller module failure. An alarmcondition causes Led IDU to steady lights up.Warning: The replacement of controller module requires the spare to be realigned (see chapter 26INSTALLATION ONTO THE POLE OF THE ODU WITH INTEGRATED ANTENNA (KIT V32307, V32308,V32309) or 28 INSTALLATION ONTO THE POLE OF THE 4 GHz ODU WITH SEPARATED ANTENNA(KIT V32323)).

43 COMPOSITION OF OUTDOOR UNIT

43.1 GENERAL

The ODU consists of a mechanical structure that houses all the transceiver circuitry. In 1+1 version theconnection to the antenna is performed through a passive hybrid.

Both transceiver and hybrid are offered in different versions depending on the operating bands, the anten-na configuration etc...

A label (see Fig.228) attached on the ODU structure shows the most significant parameters as go/returnfrequency value, subband, operating band and part number.

From ODU name (e.g. AL18 or AS18) you can see the version of used ODU.

For example the P/N GA0001/001, shown by the label, identifies the following:

- AL18 18 GHz operating band

- G/R 1010 MHz go/return frequency value

- SB 1L operating subband low

- S/N serial number

- DATA CODE month and year

A further label is available attached on the hybrid body as per example of Fig.229.

It shows the position of each transceiver and the type of coupler, balanced or unbalanced.
