Procedure 5-5: Equip new Alcatel-Lucent 1665 Data Multiplexer shelves for multishelf Digital Cross-Connect System (DCS) applications

- Overview

Use this procedure to initially equip and test new Alcatel-Lucent 1665 DMX shelves for multishelf Digital Cross-Connect System (DCS) applications.

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

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 DMX 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.

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 20 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.

- Multishelf Digital Cross-Connect System (DCS) configuration

The multishelf DCS configuration supports adding additional DS1 and DS3 (TMUX) I/O capacity to a Alcatel-Lucent 1665 DMX system by adding DS1 and/or DS3 subshelves, while maintaining the ability to externally manage the entire system using a single TID. The multishelf DCS configuration consists of one main shelf that supports up to the following maximum number of subshelves (based on equippage):

  • 12 DS1 subshelves (subshelves 2 - 13) and 1 DS3 subshelf (subshelf 14), or

  • 2 DS3 subshelves (subshelves 2 - 3)

Refer to Multishelf Digital Cross-Connect System configuration examples at the end of this procedure for examples of multishelf DCS configurations.

The transmission link between the main shelf and each subshelf is a unidirectional non-revertive 1+1 protected OC-n line (OC-12 for a DS1 subshelf and OC-192 for a DS3 subshelf).

The intershelf control communications link between the main shelf and each subshelf requires an external 100Mb hub connecting the DLAN connectors of the main shelf and each subshelf.

Important!

The multishelf DCS configuration is only supported by the Alcatel-Lucent 1665 DMX High Capacity Shelf (DMX-HC-20A, DMX-HC-30A, or DMX-HC-30A-CE Shelf Type). The Standard Alcatel-Lucent 1665 DMX Shelf does not support the multishelf DCS configuration.

Main shelf

Main shelves equipped with Very Large Fabric (VLF) OLIU circuit packs in the main slots may be provisioned to support subshelves. This is required to support the maximum number of available portless TMUX ports on the LNW20 48TMUXDS3EC1 circuit packs in the main shelf.

All provisionable cross-connections occur in the switch fabrics on the main shelf. Cross-connections are fixed on the subshelves.

The main shelf also supports all pre-existing functionality.

DS1 subshelf

A DS1 subshelf supports up to 4 pairs of LNW801 56DS1/E1 circuit packs in the Function slots (Growth slots not used) and one pair of LNW48/50/54/203 OC-12 packs in the Main slots. If other circuit packs types are installed, the system reports an unexpected CP type alarm. The LNW801 circuit packs are configured for DS1 ports. E1 interfaces are not supported in this release. The OC-12 ports on the main circuit packs must be configured as a unidirectional nonrevertive 1+1 OC-12 protection group.

The cross-connections on the DS1 subshelves are fixed and provide nonblocking access in the main shelf to all 224 DS1 signals in the subshelf.

DS3 subshelf

A DS3 subshelf supports up to 4 pairs of LNW20 48TMUXDS3EC1 circuit packs in the Function slots (Growth slots not used) and one pair of LNW56/57/58/502 OC-192 packs in the Main slots. If other circuit packs types are installed, the system reports an unexpected CP type alarm. The ports on the LNW20 circuit packs are configured as ported DS3 ports. Both channelized and unchannelized operation is supported. EC1 interfaces are not supported in the release. The OC-192 ports on the main packs are configured as a unidirectional non-revertive 1+1 OC-192 protection group.

The cross-connections on the DS3 subshelves are fixed and provide nonblocking access in the main shelf to all 192 DS3/5376 DS1 signals in the subshelf.

Main/subshelf provisioning restrictions

The following restrictions apply when provisioning the main shelf to recognize a subshelf in a multishelf DCS application.

  • The main shelf is recommended to be a Alcatel-Lucent 1665 DMX High Capacity Shelf (DMX-HC-20A, DMX-HC-30A, or DMX-HC-30A-CE Shelf Type).

Reference:

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

6

Important!

Any OLIU circuit pack in the main shelf which supports the required interface rate may be used for a subshelf interface. However, using an OLIU circuit pack in the Growth slots maximizes the number of slots available for electrical packs with external backplane interfaces (DS1, DS3, TMUX).

The LNW55 OC3/OC12/OC48 circuit pack supports OC-12 lines connecting up to 12 DS1 subshelves.

Install any required low-speed OLIU circuit packs at the main shelf for the unidirectional, nonrevertive, 1+1 OC-12 lines to the required DS1 subshelves.

Reference:

Procedure 4-3: Install OLIU circuit packs in Function slots

7

Important!

The LNW48, LNW50, LNW54, or LNW203 OC-12 OLIU circuit packs are required in the Main slots at a DS1 subshelf.

The LNW56, LNW57, LNW58, or LNW502 OC-192 OLIU circuit packs are required in the Main slots at a DS3 subshelf.

Install the required circuit packs in the Main slots at each DS1 and/or DS3 subshelf.

Reference:

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