2.1.10. EOW channels extension

EOW channels extension allows to extend the EOW telephone channel through the 4-wires RJ-41 connector on Sergi/Service board. Three configurations are supported:

1. EOW extension on a single NE;

2. EOW pass-though between 2 NEs on different SDH transmission network;

3. EOW party-line among multiple NEs.

EOW extension on a single NE is accomplished by adopting MSN8 (see WTD Commercial Product Catalog) and getting signal from 4 wire extension on the OMSN (RJ-41 connector).

EOW pass-though, between 2 NEs on different SDH transmission network, uses 4 wire extension on the two NEs to let the communication channel pass.

EOW party-line among multiple NEs uses MSN8 (see WTD Commercial Product Catalog) to connect all the 4 wire extension on all the equipment. Party line function on the MSN8 allows to make the cross connection for the voice channels.

2.1.11. On-line BUS diagnostic To improve the hardware failure diagnostic and Localization a mechanism named "NGI Monitor" (NGI, New Generation Interface, is the internal signal interface (backplane) for OMSN family). NGI Monitor allows a more detailed monitoring with respect to the current generic "Card Fail" alarm. This mechanism provides information about problems affecting internal links. Figure 1 On-line bus diagnostic shows a functional sketch of what is achievable in terms of alarms, by mean of NGI monitor. At CT Level (surveillance alarms) the number of slot where the failure occurred is reported.

If the external power supply connected to CONGI (A/B) board is faulty the alarm indication with probableCause FuseFailure is raised at NE level together with the alarm Battery Failure at equipment level on the involved CONGI (A/B).

If the fuse inside the CONGI is broken, the alarm indication with probableCause FuseFailure is raised at equipment level on the CONGI which has the fuse broken.

If there is a failure affecting On Board Power Supply (OBPS) device providing the 3.6v, the RUP alarm (Card Fail) is declared at equipment level on the affected CONGI.Another alarm is revealed directly by Equipment Controller when the auxiliary power supply at the voltage of 48V is missing, in this case the alarm with probableCause AndBatteryFailure is raised is raised at NE level (this is applicable to CONGI A only).

2.2. EQUIPMENT PROTECTION

1660SM is able to manage the following cards EPS protection:

MATRIX card protection:

As the synchronization, the matrix and the shelf controller functionalities are on the MATRIX board, the equipment protection of the MATRIX board provides the duplication of all these functions. The CRU, matrix, SC functions and the Gate array present on the MATRIX board are considered in terms of EPS as a single block. Then when a failure occurs for one or more of these, a switch is performed from the main to the spare card.

Low Speed Port Protection:

Protection scheme N+1 with fixed position of protecting Low Speed card.

High Speed Port Protection:

Protection scheme N+1 for the electrical High Speed ports.

ATM Matrix card protection:

See related ATM release note for details.

Switching time: < 50msec

Performance on matrix protection is given 15min after power-up.

The following table describes the supported commands by 1660SM:

2.3. MANAGEMENT

The 1660SM can be managed through different communication interfaces by following described:

The system can be managed through the F interface, by a CMISE Craft Terminal running on a Personal Computer (Local Craft Terminal).

A given Network Element can be configured as a Mediation Network Element in order to manage a network made up of a maximum of 32 SDH elements including the one acting as a MNE (Remote Craft Terminal). By means of the information shared through the embedded DCC channels, its possible to perform alarm synthesis and clock/data distribution of the configured managed network.

The different products of the Alcatel-Lucent Network Management System can be used to supervision the one or more NEs through the QB3 interface via a dedicated LAN port (ISOOSI protocol stack on QB3/QECC).

The QECC interface (D4D12 or D1D3 (Sw selectable)) via STMN input ports allows further connection facility to the NMS (QECC on RS/MS SOH bytes).

The system can work as a Mediation Device in order to manage from CT o OS other ALCATEL-LUCENT non SDH Equipment (video, radio, access...) through the Q2/RQ2 interface (Q2RQ2/LTS Mediation Function).

A modification into the OSI stack has been introduced to extend the number of octets of the L2 frames received over DCC: from 512 (default value defined into standard G.784) to 1520. This modification allows the interworking with those equipment sending L2 frames over DCC exceeding 512bytes.

2.3.25. AUTO MON status on SDH and PDH ports

In order to prevent alarms from being raised and failures being reported during trail provisioning actions, trail termination functions have the ability to enable and disable fault cause declaration. This is controlled via their termination point mode or port mode parameter.

The termination point mode (Figure 4) shall be either "monitored" (MON) or "not monitored" (NMON). The state shall be MON if the termination function is part of a trail and provides service and NMON if the termination function is not part of a trail or is part of a trail which is in the process of set-up, breakdown or re-arrangement.

Figure 4 Termination point monitoring state

In physical section layers, the termination point mode is called the port mode. It has three modes (see ): MON, AUTO, and NMON. The AUTO mode is like the NMON mode with one exception: if the LOS defect clears, the port mode is automatically changed to MON. This allows for alarm-free installation without the burden of using a management system to change the monitor mode. The AUTO mode is optional. When it is supported, it shall be the default mode; otherwise, NMON shall be the default mode.

2.4.10. AIS on PDH ports

AIS alarm on 2 and 34 Mb/s ports is provided on unframed 2/34 Mb/s signals.

2.4.11. ISA Ethernet main board

10/100 Mb/s Ethernet units allow creating inside of OMSNs a LAN to LAN connection as a point to point between two routers or switches through an SDH network. The board acts as a gateway towards the SDH network. Ethernet frames are mapped over a SDH VC using Generic Framing Procedure (GFP) encapsulation.

The Ethernet traffic, opportunely mapped in the SDH transport structures, is then sent toward the SDH matrix from the backPlane, which has 4 STM1 equivalent bandwidth throughput.

Ethernet frames are mapped over an SDH VC among the following:

VC12

VC3

VC4

One Ethernet interface is mapped in one SDH VC: no grooming of Ethernet frames in the SDH network is provided within this release. Protection occurs at SDH level.

Service requirements for the unit:

Point-to-Point interconnection;

No MAC Address Filtering: all what is received is transported. Local traffic is rerouted by an external switch;

Max Density of Ethernet 10/100 interfaces;

Protocol Transparency: Ethernet frames are transported on the other side as they are;

Bandwidth Compression: the allocated bandwidth on the SDH network is less than max bandwidth of the Ethernet interface (10 Mb/s, 100 Mb/s).

2.4.12. ISA Ethernet access board

The Ethernet access card is placed in the access area and is able to provide 14 x 10 /100 Mb/s Ethernet interfaces to allow LAN to LAN connections. On this access card only the physical interface function is implemented, so it must be used in conjunction with the relevant ETHERNET port where the signal is processed in order to be transported in the SDH virtual containers.

2.4.13. ISA-Gb Ethernet rate adaptive access module

It this SW release it is possible to use 2 out of 4 GbE interfaces in the ISA-Gb Ethernet rate adaptive access module in conjunction with the ISA Ethernet 10/100 port. Each GbE i/f is mapped into 1xVC4 using the GFP encapsulation. The ISA Ethernet 10/100 port controls the Gb-Ethernet access module.

In this release the frame length supported is extended to 2K.

2.4.15. LCAS functionality on ISA GbEthernet rate adaptive

The Link Capacity Adjustment Scheme (LCAS) functionality has been introduced in the ISA GbE board. LCAS implementation is compliant to ITU-T G.7042/Y.1305 LCAS for virtual concatenated signals allows to cope with the following needs, relevant to ethernet signals mapped over a bundle of SDH VCs (1 to 7 VC4s):

variable bandwidth management ;

fault and recovery management.

LCAS enables hitless bandwidth management through the following capabilities:

On-demand add server VC4v to increase the bandwidth devoted to Ethernet transport service;

On-demand remove server VC4v to decrease the bandwidth devoted to Ethernet transport service.

2.4.27. 4 X ANY UNIT

The 4xANY board allows multiplexing in the time domain up to 4 client signals into one single 2.5Gb/s optical channel (server signal). A mixing of SDH and Data Services is possible. Multiplexing scheme delivers a fully compliant SDH frame. The signal can hence be directly connected to a SDH ADM/DXC without requiring prior de-concentration.

Up to 4 client signals can be independently handled among the following types: Fast Ethernet, FDDI (125Mbps), ESCON (200Mbps), Digital Video (270Mbps), Fiber Channel (1.0625Gbps), FICON (1.0625Gbps), Gigabit Ethernet (1.25Gbps). Server STM-16 signal is connected to SDH matrix through 1660SM back panel.

The board (8TE wide) is applicable to 1660SM only. It can be plugged in "Enhanced HS slots" (slots: 25&26, 28&29, 34&35, 37&38) to fully exploit up to 2.5Gb/s (16 x AU4s) throughput; if plugged in standard "HS slots" (slots: 30&31, 32&33), up to 1.2Gb/s (4 x AU4s) bandwidth is available. Insertion of the board across hybrid slots ("enhanced HS slots" + "HS slots") is not managed.

As far as client signals allocation is concerned three cases has to be distinguished:

4xANY unit plugged in "enhanced HS slots": client signal allocation is shown in Figure 6;

4xANY unit plugged in "HS slots": client signals allocation is shown in Figure 7.
