ICC - Indoor Combiner Circulator

The ICC sums the Rx and Tx signals and combines the N channels to the output ports (one or two, inaccordance with the configuration).

There are two types of ICCs:

- ICC - does not perform summing of space diversity ICBs (single output port)

- ICCD - performs space diversity ICB summing (two output ports)

Within these types, there are two sub-types:

ICC3/ICCD3 - sums up to three ICBs

ICC5/ICCD5 - sums up to five ICBs

For example:We will assume a SLT system in a 4+1 dual polarization configuration, as shown in the illustration below.

In this configuration, three ICBs are chained together and connected to a vertical ICC, and two ICBs arechained together and connected to a horizontal ICC.

The RF components will include:- Five RFUs- Five ICBs- Two ICCs

Horizontal ICC

RF Filters

The RF Filters are used for specific frequency channels and Tx/Rx separation. The filters are attachedto the ICB, and each RFU contains one Rx and one Tx filter.

In a Space Diversity configuration, each RFU contains two Rx filters (to combine the IF signals) and oneTx filter.

1.9.2 – Baseband Indoor Components

SLT Indoor Unit

IDC - IDU Controller

The IDC card is responsible for the management of the Baseband Indoor. Management includes all FCAPSfunctionality (Fault, Configuration, Accounting, Provisioning, and Security).The indoor is equipped with up to five IDMs that can be installed in three floors:

- Floor 1 - 2 IDMs- Floor 2 - 1 IDM and XC card- Floor 3 - 2 IDMs

Each IDC manages the relevant floor, according to its location.

IDM - Indoor Module

The IDM is the data carrier, which consists of two independent drawers:- Multiplexer drawer- Modem drawer (IF)

The Multiplexer drawer is a standard SDH/SONET regenerator. It receives standard SDH/SONET data fromits line interface and transfers the data to the Modem drawer.

The line interface can be one of the following:- Optical interface, single-mode,1300 nm, SC connector- Optical interface, multi-mode,1300 nm, SC connector

- Electrical interface, CMI/1.0-2.3

The Modem drawer is a multi-constellation modem that performs data conversion from the basebandfrequency to the IF frequency, and vice versa.The Multiplexer and the IF drawer are hot swappable cards that can be replaced while the indoor isoperating.


XC - Switching Board

The XC board is responsible for the N+1 functionality.When a radio problem occurs in one of the N links, the XC board builds an alternative path between thelocal and remote Multiplexer drawers. The switch between the paths is performed using the Hitless method.

Connection Panel

The fourth floor of the Baseband Indoor is responsible for most of the sub-rack connectivity. It includes theAuxiliary board, N-type connectors, and two power supply feeding boards.

N-Type Connectors

These are IF cable connectors located on the Connection Panel, which connect the Baseband Indoor andthe RFUs.

Power Supply Feeding Board

This board is responsible for the power distribution in the Baseband Indoor. There are two power supplyinput boards for power input redundancy.

Auxiliary

This board is responsible for all auxiliary traffic, including the Wayside Channel (E1, T1, Ethernet),management port interface, 64 Kbyte User Channel (V.11, RS232, Ethernet), and Engineering OrderWire.

1.9.3 – Power Supply

SAGEM-LINK T operates on DC power, which feeds the baseband indoor.A dual power source feeds two power distributor cards at the fourth level of the baseband indoor. Thesepower feeds back up each other and distribute the power to the different IDMs, which, in turn, feed theRFUs.The operational power supply range is -40.5V to 60V.


1.10 – Auxiliary Channels

The following Auxiliary channels are available:

Wayside Channels

Up to four wayside channels can be used per baseband indoor. Each channel is dedicated to a singlecarrier.

The wayside channel type can be:

1. E1/Ethernet, software configurable

2. T1/Ethernet, software configurable

User Channels

Up to four user channels can be used per baseband indoor. The rate of each channel is up to 64 kbps.

The user channel type can be selected and configured via the LinkPilot management application.

Each user channel can be individually configured (as shown in the LinkPilot window below).

The user channel type can be:

• Asynchronous - RS-232 or V-11 (up to four channels)

• Synchronous - co/contra directional (up to four channels)

• Ethernet (up to four channels)

Note that an optional VoiP phone can be connected to the user channel Ethernet port, to enable dialingfrom one terminal to another terminal.

LinkPilot Auxiliary Channel Configuration


Other Auxiliary Channels

Additional auxiliary channels include the following:

• EOW - 64 kbps connection for a headset (earphone + microphone), enabling voice (broadcast) fromone terminal to another terminal.

• External alarms - 8 inputs, 5 outputs

1.11 – Radio Protection Switching

The following is a description of the radio protection switching concept and functionality.

The N+1 radio protection system protects N carriers using an additional (+1) carrier (using diversefrequency channel or diverse polarization). When a fault is detected on one of the N carriers, a request fora protection path is sent to the remote side. The remote side then sends the traffic of the faulty carrier viaboth the regular and protected paths.

The transaction between the normal and diversity traffic is hitless, ensuring continuity of the data frameand clock. The faulty period is less than 10 ms.

Errorless switching is configured when setting up the switching criteria (“Switch on early warning”).

If the system detects more than one fault, the N+1 system will service the most severe fault first, wherebythe severity is defined in accordance with the following table.

Fault Priority Table

# Event Priority Remark

1 LockOut 1 (high) No switching is allowed, userconfiguration

2 Force Switch 2 Force protection of requiredchannel, user configuration

3 Radio (BB) LOF 3BB LOF indication from modemcard, or recognized by XC (loss offrame), or missing modem card

4 BB Excessive BER 4 High BER (>10e-6), XC calculation

5 BB SignalDegrade 5 Low BER (<10e-6), XC calculation

6 Early Warning(MSE) 6

Degradation of MSE underrequired reference; errorlessswitching

7 Manual 7 Protect required channel ifavailable, user configuration

8 None 8 (low) No protection switching required

Radio protection switching is performed by the XC card, through which all carrier traffic passes through, asshown in the following illustration.

The XC card supports up to a 4+1 configuration. For additional carrier protection, an additional basebandindoor is added, and two XC cards are chained, enabling support for up to a 9+1 configuration.


One IDU in the chain is configured as the primary and the other as the secondary. The chaining modeenables the addition of five carriers for a 9+1 configuration.

Chaining is done using the XC chaining connector, and requires an SFP cable.

1.11.1 – Channel PrioritiesThe user can configure two priority groups:

• High priority

• Normal priority

Another associated configuration is the high priority threshold.

The following rules define the XC selection algorithm:

• If two carriers report a fault with a similar severity, the first channel will be serviced first.

• If two carriers from the same priority group report a fault, the channel with the most severefault will be serviced first.

• If two carriers from different priority groups report a fault, and the fault severity of the highpriority channel is greater than the high priority threshold, that channel will be serviced first.Otherwise, the previous rule will define the preferred channel.

• If the system detects more than one fault with the same severity, the link with the higherpriority will be serviced first, whereby the link priority is configured by the user.


1.11.2 – Revertive ModeThe user can work in revertive or non-revertive mode. In revertive mode, the system automaticallyreturns the data to its original path when a fault situation is resolved.

In non-revertive mode, the system continues to protect the last channel (errorless protection) untila new higher priority fault occurs.

1.11.3 – Upgrade / DowngradeThe user can add a carrier to the N+1 group by inserting the module and setting a configurationcommand. When a new carrier is added to the N+1 group, the XC receives its status and handlesits requests, as with all other carriers.

All cards are hot-swappable (can be inserted during live traffic).

In the RF subrack, a new ICB with its filters and RFU will be chained to the existing ICBs.

1.11.4 – Link Topologies

The following configurations of SLT drawers were defined for various topologies. Note that theseconfigurations should be implemented exactly as described, for proper system functionality.

Chapter 4Initial System Setup

4.1 – General

After the system is installed and antenna alignment is performed, the next step is initial IDU setup andconfiguration.

Initial setup procedures are performed on a craft terminal via a serial port connection. Additional setupprocedures are performed using the LinkPilot software supplied with SAGEM-LINK T.

For a complete description of LinkPilot, refer to the SAGEM-LINK A installation and user manual (providedin the CDROM).

Note: The craft terminal should be used only to perform the initial setup procedures described in thischapter. Once the system is up and running, use LinkPilot to maintain and operate the system on a regularbasis.

4.2 – Initial Setup Steps for up to 4+1 Configuration

The following initial setup procedure refers to one SLT IDU at each site, which allows the user to reach aconfiguration of up to 4+1 (five carriers).

The procedure includes the following steps:

Procedures Performed using a Craft Terminal:

• Connecting to the IDU via serial port. The SLT IDU consists of three levels (IDCs) that need to beconnected to.

• Defining IP addresses for each one of the three IDCs.

• Setup options.

Procedures Performed using Link Pilot :

• Connecting to the Ethernet ports (two ports on the top panel of the IDU)

• Installing the software

• Starting LinkPilot and connecting to the unit, specifying the IP address of the middle level (IDC)

• Setting the local Tx frequency channel for the five carriers

Note: The protected carrier is the one connected to the upper left drawer.• Specifying system information

• Configuring the local/remote transport

• Configuring trap forwarding

• Setting up external alarms

Connecting the Line Interfaces


4.3 – Initial Setup Using the Craft Terminal

The following procedures are performed after the ODU/RFU and antenna are installed.

4.3.1 - Connecting to the IDU via Serial PortTurn the IDU power switch ON, and note the following:

• Make sure that the color of the main power LED on the IDU front panel is blue. (Note that there aretwo main power inputs to the IDU.)

• On the front panel of each of the five IDMs, make sure the color of the power LED is green.

To set up the HyperTerminal connection:

1. Connect the RS-232 port of your computer to the RS-232 (9-pin) port on the IDU front panel. Thisport is labeled “Terminal”.

2. Select Start, Programs, Accessories, Communication, HyperTerminal.

3. Double-click the HyperTerminal application icon.

4. For Connection Description, type Terminal, and click OK.

5. In the Connect Using field (Phone Number), select Direct to Com 1, and click OK.

6. In the Port Settings tab (Com 1 Properties), specify the following settings:

• Bits per second - 19,200

• Data bits - 8

• Parity - None

• Stop bits - 1

• Flow control - Hardware

7. Click OK.

8. After you connect to the terminal, to enter the terminal setup program, press Enter.

9. For password, use admin.


4.4 – Initial Setup Steps for up to 9+1 Configuration

Cascading two SLT IDUs at each site will enable a configuration of up to 9+1 (10 carriers), or XPIC 7+1with two additional carriers.

The setup steps for a configuration of up to 9+1, are identical to those of the configuration of up to 4+1 (seeabove) except for the following differences:

• You must configure all six IDCs using the HyperTerminal.

• You must specify if you are using cascading mode, using the HyperTerminal

• You must specify in which IDU the protected link will be defined.

4.4.1 - To set the cascading mode:1. In the main terminal program menu, select Configuration.

2. Select System configuration.

3. Select Cluster configuration.

Specify the number of sub-racks in the system. 1 for stand alone, or 2 for cascading mode.

Specify either 1 or 2 for the sub-rack number. The protected carrier will be in sub-rack 1.

4.5 – Defining IP Addresses

Before you can configure the SLT system, you need to define four IP addresses using the craft terminal.

SAGEM-LINK T includes three levels of two IP interfaces: an Ethernet interface, and a serial interface.Each interface has its own IP address and IP mask.

You must configure an IP address for each of the three IDCs - a unique shelf number for each shelf in thecluster.


In addition, you must define same base IP address for every SLT IDC. The address is a four digit numberseparated by decimal points. Each IP address is a pair netid-hostid, where netid identifies a network, andhostid identifies a host on the network. The IP mask separates between the netid and hostid.

For example, if the IP address is 192.114.35.12 (11000000 01110010 00100011 00001100), and the IPmask is 255.255.255.0 (11111111 11111111 11111111 00000000), the netid is 192.114.35, and the hostidis 12.

An IP interface can only communicate with hosts that are on the same net (have the same netid). In theexample above, the interface can communicate only with hosts that have netid 192.114.35 (for 1 to 255).

If SLT has a frame to send to a host that is not on the Ethernet IP netid or the serial IP netid, the frameshould be sent to an intelligent device (usually a gateway) on the network. Such a device, known as a"default router", will know how to send the frame over the internet. The default gateway should be a host onone of the SLT interface netids.

The SLT cluster is managed as a single Network Element (NE) by the LinkPilot software.

The following figure illustrates a SLT management model from an EMS/NMS point of view.

LinkPilot

SLT GNE A SLT NE B

SLA NE C

SLA NE D

Each IDC calculates its own IP address, considering cascade shelf# and floor#:##*3 floorshelfIPbaseIP ++= ,

where:

IPbase is dividable by 8 (i.e. = IPbase & 0xfffffff8),

shelf# = 0, which is the cascade master (the one with the protected carrier), or 1 for cascade slave,

floor# = 1, 2, or 3 (the number of the floor within the SLT shelf)

In-Band Management

In-band management of the SLT link chain must be configured carefully due to a large number of public IPaddress allocations. In addition, it should be noted that in-band management becomes a limiting factor forchain length when only the Class C DCN is used.

The figure below illustrates the largest Class C in-band subnet (with CIDR = 26 bits, i.e. subnet mask255.255.255.192).


The DCN shown in the figure makes use of the 192.168.1.64 in-band subnet. This subnet allows 62 nodes192.168.1.65 - 192.168.1.126, and has a broadcast address of 192.168.1.127.

It is assumed that the SLT at site A has a single GNE 1 assigned to one of the IDCs.

All three IDCs at site A have direct out-of-band IP connectivity with remote management applications(LinkPilot, IONOS-NMS...). The remaining SLT chain IP addresses are accessed via the GNE IDC.

LinkPilot

SLT GNE 1 SLT NE 2

SLT NE 3

SLT NE 6

SLT NE 7SLT NE 8SLT NE 8

SLT NE 5

SLT NE 4

Note that the Inband bytes run through the upper level of the cluster.

The Ethernet interface of every Network Element (NE) is assigned the CIDR=/29 subnet, i.e. subnet mask255.255.255.248. This allows 6 elements to be communicated over the interface. These addresses can befully utilized when two SLT shelves are cascaded for 7+1 group protection.

The figure above shows “back-to-back” connected SLT shelves at the same sites: B, C, and D, forEast/West chaining. Two NE IDCs (NE 2 and NE 3), at the same site, are connected over a PPPoE link.

This scheme allows four links of up to 7+1 (eight SLT shelves, as shown, or sixteen SLT shelves cascadedin pairs) chained through the same LinkPilot management, when IP addresses are allocated as describedabove.

Notes:

1. The CIDR=/29 subnet allows external element communication (such as a laptop connected to thesite B LAN) only if there are less than six IDCs operating on two cascaded SLT shelves. The subnetis not sufficient for three SLT cascading shelves. Three cascaded shelves require CIDR=/28 nodes(subnet mask 255.255.255.240). This reduces the available number of chained links to 50%.

2. High protocol timing constraints (SNMP/TFTP) are expected in SLT link chains due to the largenumber of hops (each East/West site adds two in-band routing hops), and a large number ofmanaged IDC nodes.

The following slight optimization may be useful for a chain topology (but not for a ring):

One of the in-band NE management channels is configured as a Default GNE Direction, assumingthe channel leads to the nearest GNE under normal conditions. Then, in-band routing chooses thischannel as a first priority for every “in-band packet” generated internally, or received from theEthernet interface.

To define IP Addresses:1. In the main terminal program menu, select Configuration.


2. Select System configuration.

3. Select IDC configuration.

4. Select IDC Basic configuration.

5. Select IP.

6. Define the addresses as described above: element IP and basic IP of the units.

Important: After you set up IP addresses, restart the IDUs to activate them.

7. Repeat the steps above for the remaining IDCs in the SLT IDU.


4.6 – Setup Options in the Terminal Program

The main menu in the terminal setup program includes the following options:

Configuration (1) - the main setup section in which you can configure the IDC, the right and left drawers,protection, SNMP management, in-band routing, and other such parameters.

System Status (2) - used to obtain information about the different software versions currently used in thesystem.

Maintenance (3) - used to perform software upload, download, and reset.

Diagnostics (4) - used to perform loopbacks and obtain system information.

Logs (5) - used to view alarm and configuration log reports.

4.7 – Additional Setup Using LinkPilot

After you perform initial setup via the terminal, some additional procedures should be performed viaLinkPilot software.

Note: The information in this section is provided only for basic initial setup. More detailed information aboutLinkPilot can be found in the SAGEM-LINK A Installation and Operation manual (provided in the CDROM).

Connecting to the Ethernet Port1. Connect a crossed Ethernet cable from your PC to the Ethernet Port. If the connection is to a LAN

(wall connection), use the standard Ethernet cable.

2. Make sure the IP address on your PC is on the same sub-net as the one you defined for the SLT IDU(in most cases, the first three numbers of the IP address must be identical, depending on the sub-netmask).

LinkPilot PC RequirementsBefore you install the LinkPilot software, verify that your PC has the following minimum requirements:

Windows

Processor: Pentium 4, 2.8 GHz (minimum)

Memory (RAM): 256 MB minimum

5. Select Switch On Early Warning if you want the switch to occur when the system reaches an MSEof -28.

6. For Revertive Link, select the carrier that will be connected to the +1 modem. Your selection will beused in cases where a switch occurs and then the system returns to normal operation.

Examples

Revertive = Extra TrafficIf a major alarm occurs at site A, a request is sent to site B to transmit through the Extra Trafficchannel. The switch that is performed is Hitless (up to 10 mS), and the Extra Traffic channel will nolonger exist on both sides by definition (generally, the system can protect up to two faults at differentsides). The moment the alarm is cleared, the +1 (Extra Traffic) modem will refer to the input from the+1 MUX.

Revertive = NoneEach carrier MUX will receive two inputs: its own modem, and the +1 modem. The Extra Trafficchannel will not exist. Data to the MUX (for each of the defined carriers) will be received from its ownmodem until the first hitless fault. When the fault is cleared, the MUX will receive data from twosources: the +1 modem, and its own modem, meaning the next fault in this channel will be errorless(if other carriers will fail, the data will be hitless).

Revertive = Carrier#XMUX number X will always receive two sources: the +1, and its own, unless there is a fault in anothercarrier. If MUX number X receives two sources, and a fault occurs, the switch is errorless. In all theother cases, the switch is hitless.

7. For Revertive Switch Timeout, specify the period (in seconds) after which the revertive mode willbe activated.

8. For High Priority Threshold, click the drop-down list and select the criteria upon which the systemwill perform a switch to the channel you chose as high priority.


The options include: Baseband Loss of Frame, Baseband Excessive BER, Baseband SignalDegrade, and Early Warning

9. In the priority table, designate the high priority channel(s). A high priority channel will be switched firstwhen the criteria chosen for the threshold is met, even if a major fault occurs in a different channel.

The Priority Level options include:

• Normal - regular operation according to the N+1 mechanism

• High Priority

• Not Protected – stand-alone channel without protection

Specifying System InformationNote: To specify system information, you must perform the following steps in all three IDCs in the SLT IDU:

1. Select File, System, Information., or click the System Information icon.

Select Use different ID for each alarm type if you want each type of alarm to receive a unique ID.

Select Send “clear” traps with zero severity if you want a trap with a “clear” severity (instead ofthe alarm's original severity) to be sent to the IP addresses you specified.

5. For CLLI (Common Language Location Identifier), enter up to 18 characters that will represent yoursystem ID when traps are sent.

6. For Heartbeat Period, a heartbeat signal will be generated every x minutes (the number you enter)to tell your system that the trap mechanism is working.



External Alarms SetupThe procedure detailed in this section is required only if alarms generated by external equipment areconnected to the IDU, or if the IDU alarm outputs are connected to other equipment (using the alarms I/Oconnector).

The SLT IDU has eight external alarm inputs and five external alarm outputs. Since each of the three levelssupport five outputs, the system uses the OR function between the outputs of each floor, and accordinglygenerates the alarm.

1. Select the middle floor of the SLT IDU, and select Configuration, IDU, External Alarms.

Or, click the External Alarms icon.

Or, click the EXT ALARM IN icon on the IDU front panel.

The Input / Output External Alarms window appears.

Input / Output External Alarms WindowFollow the steps below for both the Local and Remote sides.

The microcontroller in the IDU reads alarm inputs (dry contact) and transmits them to the LinkPilotmanagement system. This allows SLT to report external alarms that are not related to its ownsystem.

For each alarm on the left side of the window, do the following:

2. Click the box next to the alarm number to enable/disable the alarm.

3. If you enable an alarm, enter a description of the alarm in the text field.

4. Select the alarm’s severity level from the drop-down list (Major, Minor, Warning, or Event).

5. SLT provides five alarm outputs that can be used by other systems to sense SLT alarms. Theoutputs are configured on the right side of the window.


The alarm outputs are Form C Relays. Each output relay provides three pins, as follows:

• Normally Open (NO)• Normally Closed (NC)• Common (C)

Output alarms can be defined as any of the following:

• Major• Minor• Warning• External• Power• BER• Line• Loopback• LOF• IDU• ODU• Cable• Remote

The default alarm output setting for each relay is “Power”.

The relays may be connected to customer-specific applications. Refer to Appendix B for detailsconcerning the alarm connector pin assignments.

6. After you complete the configuration, click Apply to save the settings.

7. Click Close.

Exiting LinkPilotTo exit LinkPilot, select File, Exit in the main window.

5.2.2 - Site Acceptance Checklist Notes

The following notes provide important additional information about the Site Acceptance Checklist.

1. Antenna Mounting

• Mounting pole is of sufficient height to clear local obstructions, such as parapets, window cleaninggantries, and lift housings.

• Mounting Pole is of sufficient height, and is safely positioned, so as not to cause a safety hazard. Noperson should be able to walk in front of, or look directly into the path of the microwave radio beam.Where possible, the pole should be away from the edge of the building.

• Mounting pole is secure and perpendicular. A pole that is not perpendicular may cause problems duringantenna alignment.

• Mounting pole is grounded as per site specifications. All operators and site owners have specificrequirements regarding the grounding of installations. As a minimum, typical requirements are suchthat any metal structure must be connected to the existing lightning protection ground of the building.Where it extends beyond the 45 degree cone of protection of existing lightning conductors, additionallightning protectors should be installed.

• All steelwork is Galvanized or Stainless Steel, as appropriate to prevent corrosion.


2. Antenna

• Antenna is grounded as per site specifications. See the third point in the Antenna Mounting sectionabove.

• Antenna sway braces are fitted and installed correctly, where applicable. Typically, for an antenna of 1.2m or larger, an extra sway brace is fitted to the mounting frame of the antenna. This sway braceshould not be mounted to the same pole as the antenna, but should be installed directly back to thetower or an alternative point.

• Antenna Water Drain Plugs are fitted and removed, where appropriate. Some antennas have moisturedrain plugs installed at various points around the antenna. The purpose of these plugs is to allow anymoisture that forms on the inside of the antenna or radome to drip out and prevent a pool within theantenna. Only the plugs at the bottom of the antenna, after installation, should be removed. All otherplugs should be left in position.

3. RFU (RF Unit)

• The RFU is grounded as per installation instructions. See the third point in the Antenna Mountingsection above.

• The RFU Polarization is as per link requirements and matches the polarization of the antenna.

4. Indoor Unit

• The main traffic connections (STM-1 tributaries) are correctly terminated and crimped as per cable andconnector manufacturer instructions. All fiber optic patch leads should be routed carefully andefficiently, using conduits to prevent damage to the cables.

All other user terminations are secure and correctly terminated.

• All labeling is complete as per site requirements. Labeling is specific to each customer. At a site withonly one installation, labeling may be unnecessary. However, at sites with multiple installations,correct and adequate labeling is essential for future maintenance operations.

Typical labeling requirements include:

Antenna labels - for link identity and bearingRFU labels - for link identity, frequency, and polarizationCoax cable labels - for link identity, close to the RFU, IDU, and either end of any jointIDU labels - for link identity


5.3 – N+0 Commissioning Procedure

5.3.1 - ScopeThis section describes the recommended commissioning tests for a SAGEM-LINK T radio link in an N+0configuration.

The purpose of the commissioning tests is to verify correct and proper operation of the product.

The SLT system can work with up to a 9+1 configuration (two systems in concatenation mode).

The +1 carrier protects the other N carriers, and in normal operation of the system (no errors or faults),carries extra traffic.

The first tests should be performed on all carriers, including the extra traffic channel, separately.

When testing protection using switching tests, there is a difference if a channel is a preferred channel(errorless, no errors at switching time at all), or if it is a regular channel (hitless, errors are detected within10 ms).

5.4.2 - Commissioning TestsThe following tests should be performed on each installed link.

Link VerificationThe following steps should be repeated for each of the N+1 RFUs.

• “Radio” LED on the IDM front panel is green, indicating the radio link is up.

• Received Signal Level (RSL) is up to +/- 4 dB from the expected (calculated) level at both ends ofthe link.

• Radio Bit Error Rate (BER) is 10E-11 or higher.

• If working with ATPC, ATPC is operating as expected (RSL = reference level).

• After connecting test equipment or end equipment to the line interfaces, all LEDs on the front panelof the IDM are green.

Line Interfaces Test• 155 Mbps Interface

Connect SDH/SONET/ATM test equipment to the 155 Mbps interfaces using splitters. Verify error-free operation for at least 1 hour. Use physical loop between the splitters at the far end.

• 2 Mbps/1.5 Mbps Interface

Connect PDH test equipment to the E1/T1 interfaces of an ADM connected to the IDU using splitters.Verify error-free operation for at least 1 hour. Use physical loop between the splitters at the far end.

155 Mbps Interface• Connect SDH/SONET/ATM test equipment to the

155 Mbps interfaces using splitters. Use physical loop between the splitters at the far end. Verify thatthere are no alarms.


• Perform the following switching tests from one IDMto the other, and verify the system switches automatically.

- Power: power off the active IDM

- Radio: disconnect the coax cable of the active IDM

- Line: disconnect the 155 Mbps line input of the active IDM

- Management: force a switch using LinkPilot

• For diversity configurations, verify that eachreceiver is receiving its own signal, and then mute the active RFU. Verify that the receiver at the farend still receives from the diversity path. Verify that there are no errors in the test equipment.

Interoperability Verification• Connect the customer end equipment to

the line interfaces and verify correct operation.

• Further interoperability tests should be performed inaccordance with the specific requirements of the connected end equipment.

Management Verification• Install LinkPilot software on the PC and launch the program.

• Verify that you can manage the link and that you are able to performchanges to the link configuration (frequency channel, Tx power, system name, time & date, etc.) viaLinkPilot.

• Verify that LinkPilot reports the correct parameters when performing the above.

• Verify that there are no active alarms on the link.

If the management station is located at a remote site (Network Operation Center), verify that themanagement station can manage the link and receive traps.

5.5 – XPIC Commissioning Procedure

5.5.1 - ScopeThis section describes the recommended commissioning tests for a SAGEM-LINKT radio link in an XPICCo-Channel-Dual-Polarization configuration.


Important! Since operation of the XPIC system depends on correct installation, make sure the guidelinesfor XPIC system installation provided below are followed correctly.

The SLT system can carry up to two XPIC links per IDU. The XPIC mode runs between drawers 1-2 and 4-5 in the IDU.

All tests described below should be performed separately for each XPIC pair in the IDU.

5.5.2 - XPIC Installation Guidelines

Antenna and RFU Installation

1. Install the dual polarization antenna and point it in the direction of the other site.

2. Install the two RFUs on a rack, and mark them with V and H respectively.


IDU-RFU Cable Installation

1. Connect two cables between the RFUs and the drawers (IDMs). Note that the cable lengthdifference should not exceed 10 meters.

2. Mark the cables with V and H respectively, and make sure V is connected to the right drawer and His connected to the left drawer.

3. Mark the drawers respectively.

Antenna Alignment

1. Power up drawer V on both ends of the link and configure it to the desired frequency channel andmaximum power.

2. Align the antennas, one at a time, until expected RSL is achieved. Make sure achieved RSL is nogreater than +/-4 dB from the expected level.

Polarization Alignment

Polarization alignment is required to verify that the antenna feeds are adjusted, to ensure that the antennaXPD (Cross Polarization Discrimination) is achieved.

Polarization adjustment should be done on one antenna only.

1. Power up drawer V on both ends of the link and record the RSL reading on one end.

2. Power off drawer V on that end, and power on drawer H.

3. Check the RSL obtained on this RFU on H pol, and compare it to the RSL obtained by the RFUinstalled on the V pol.

4. Verify that the XPI (Cross Polarization Interference) is at least 25 dB

where:

XPI = RSLPOL – RSLXPOL

RSLPOL corresponds to the RSL with the same polarization used at both sitesRSLXPOL corresponds to the RSL with orthogonal polarization used at both sites

5. If the XPI is less than 25 dB, adjust the feed polarization by opening the polarization screw andgently rotating the feed to minimize the RSLXPOL.

Note that polarization alignment is not always possible since the RSLXPOL may fall below thesensitivity threshold of the RFU.

It is also recommended to try to maximize the XPI as much as possible, by aligning the polarization.

5.5.3 - XPIC Commissioning Tests

Individual Link Verification

Before operating in XPIC configuration, each of the links (V and H) should be commissioned individually inorder to verify its proper operation.

1. Power up only drawer V at both ends and verify its frequency channel and Tx power configuration.

2. Verify that the RSL is no more than +/-4 dB from the expected level.

3. Run BER stability test on the link for at least 15 minutes to ensure error-free operation.

4. Power up only drawer H at both ends and verify its frequency channel and Tx power configuration.


5. Verify that the RSL is no more than +/-4 dB from the expected level.

6. Run BER stability test on the link for at least 15 minutes to ensure error-free operation.

XPIC Configuration Verification

1. Using the XPIC cable, connect the two RFUs at each end to the TNC connectors. Make sure thecable is no longer than 3 meters.

2. Configure the drawers to work in XPIC mode.

3. Verify that the RSL at all four RFUs is no more than +/-4 dB from the expected level.

4. Verify that no alarms exist (if a 155 Mbps line is connected).

5. Run BER stability test on each of the 155 Mbps links for at least 1 hour to ensure error-freeoperation.

XPIC Recovery Verification

In order to verify XPIC operation, simulate the faults described below.

1. Disconnect the IDU-RFU cable for each of the drawers (one at a time), and verify that theother link is operating.

2. Disconnect the XPIC cable and check that the relevant alarms are generated.

3. Power down each of the drawers and verify that the other link is operating.

4. Swap the V and H cables and check that the relevant alarm is generated.

5. Mute and then un-mute one RFU at a time and verify that the other link is operating.


5.6 – SAGEM-LINK T Commissioning Log

The Commissioning Log is an integral part of the commissioning procedure and should be filled in for eachinstalled link.

In an N+1 system, a commissioning log should be recorded for each of the five carriers (per IDU), includingthe extra traffic channel.

The Commissioning Log gathers all relevant information regarding the installed link and contains a checklist ofall recommended commissioning tests.

Maintaining the Commissioning Log is important for tracking your installations, and to provide essential datafor Sagem Communications.
