Procedure 5-4: Equip new Alcatel-Lucent 1665 Data Multiplexer Extend for DWDM Add/Drop Ring applications

- Overview

Use this procedure to initially equip and test a new Alcatel-Lucent 1665 DMXtend for DWDM Add/Drop Ring applications. With this configuration, the Alcatel-Lucent 1665 DMXtend is expected to be incorporated into a DWDM network using the two OTS ports of the OMD circuit packs in a Function/Growth Group.

Alcatel-Lucent 1665 DMXtend shelves equipped for DWDM Add/Drop Ring applications transport/reconfigure/manage up to 8 drops from two 8-channel DWDM OTS lines using manual pass-through fiber connections between two End Terminals. This allows Ethernet, Data, and TDM traffic groomed into the OC-192 OLIU circuit packs (with DWDM-compatible optics) and XM10G/8 circuit packs to be transported over the DWDM lines.

Alcatel-Lucent 1665 DMXtend shelves equipped for DWDM Add/Drop Ring applications can also be used for a two-line End Terminal when the pass-through fiber jumpers between the OMD circuit packs are not connected.

This procedure assumes that all hardwired installation and testing of the unequipped Alcatel-Lucent 1665 DMXtend shelf is done. It also assumes that power is applied to the shelf.

The basic purpose of this procedure is to:

  • Install and test system-required circuit packs and software.

  • Install and test optional circuit packs that you want to install at initial installation.

  • Test the Alcatel-Lucent 1665 DMXtend for proper and alarm-free operation before placing into the network.

Additional references are provided at the end of this procedure for provisioning optional system and circuit pack port parameters.

- Privilege level

You must log in as a Privileged user to complete this procedure.

Important!

Some of the steps and procedures referenced in this procedure provide information on provisioning port parameters. If you provision parameters after installing each circuit pack, then you should NOT perform the part of the procedure in Step 19 to reset all provisionable parameters to default values.

Depending on local procedures, you may set the circuit pack and/or port parameters in this procedure, or reference the appropriate procedures in this document when you are ready to establish your network and service configurations.

- Before you begin

Before you begin this procedure:

  1. Refer to Before you begin and Required equipment in this chapter.

  2. Refer to Laser safety and Electrostatic discharge information in Chapter 1, Safety.

  3. Obtain the work instructions for this procedure which state the quantity and type of circuit packs to be installed.

  4. Verify that you have the proper type and code of circuit packs being installed.

  5. If required, ensure that correct pluggable optical modules are available for installation. For reference, see Procedure 4-16: Install pluggable transmission modules.

  6. If system and circuit pack port parameters are being set at this time, ensure you have a full set of work instructions detailing the values of the parameters being set.

It is suggested that you first install and test all the required circuit packs, perform the necessary system tests, reset all provisionable parameters to factory default values, then provision system and port parameters from values given in your work instructions.

Important!

One or two high-speed OLIU circuit packs are required for synchronization in Add/Drop Ring applications.

Install high-speed OLIU circuit packs in the Main slots.

Reference:

Procedure 4-2: Install OLIU circuit packs in Main slots

5

Important!

Two OMD circuit packs are required in a Function/Growth group for each Add/Drop Ring application. The Optical Channel (OCH) ports of the OMD circuit packs in the Function/Growth group are required to be pre-equipped with pass-through fiber jumpers. This minimizes the installation time of pass-through connections when a service is established. Constant travel to pass-through nodes is avoided when a service is added.

Install the required OMD circuit packs in the Function/Growth group with pass-through fiber jumpers connecting the Optical Channel (OCH) ports.

Reference:

Procedure 4-24: Install DWDM optical multiplexer/demultiplexer circuit packs

6

Important!

OCH cross-connections to/from an OCH port are used to inform the network element about manual fiber connections. This allows the network element to enable alarm reporting and variable optical attenuators. The variable optical attenuators are enabled only when an OCH port is the destination of an OCH cross-connection.

Select Configuration → OCH Cross-Connections to access the OCH Cross-Connection Wizard and provision the required pass-through OCH cross-connections.

7

Install and provision, if required at this time, any LNW705 XM10G/8 circuit packs.
