Procedure 9-8: Establish low-speed 0x1 unprotected optical extension

- Overview

Use this procedure to establish a low-speed 0x1 unprotected OC-3/12/48 optical extension.

Important!

This procedure assumes that the low-speed 0x1 unprotected optical extension is established by interconnecting a OC-3/12/48 Function/Growth slot at the host Alcatel-Lucent 1665 DMX to a far-end node.

Ignore all alarms until the procedure is complete.

- Privilege level

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

Required equipment

In addition to the equipment listed in Required equipment, the following equipment is also required:

  • Optical power meter

  • Lightguide jumpers

  • Lightguide BuildOuts (LBOs).

- Before you begin

Prior to performing 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. Verify that you have the necessary work instructions detailing the slots, circuit packs, ports, and network element parameters to be used for this procedure.

  4. Verify that the network containing the host Alcatel-Lucent 1665 DMX node is established and operating properly.

  5. Verify that the far-end node being connected to the host Alcatel-Lucent 1665 DMX node has been equipped and is operating properly.

    If the far-end node is a Metropolis® DMXpress, verify that the application option plug (p5) on the OC48/1.3I2 Main circuit pack was set to 0x1 in the unswitched extension. Refer to the Metropolis® DMXpress Access Multiplexer User Operations Guide, 365-372-314.

Steps

Complete the following steps to establish a low-speed 0x1 unprotected OC-3/12/48 optical extension.

 
1

Determine the network configuration using the work instructions and office records. Refer to the example in Figure 9-8, Example of 0x1 unprotected optical extension.

Important!

Two or more shelves in the same network cannot have the same TID.

Using the work instructions and office records, verify that no duplicate TID settings exist between the host Alcatel-Lucent 1665 DMX and the far-end node. If duplicate TID settings exist, determine new settings and at each site with duplicate TID settings, select Administration → Set TID from the System View menu, and enter new TID settings.

Reference:

Procedure 7-11: Set/change system TID

3

If required, modify the network service access point (NSAP) address and/or enable Level 2 routing capabilities at the host Alcatel-Lucent 1665 DMX and the far-end node.

Reference:

Procedure 7-13: Provision network layer 3 parameters

4

At the host Alcatel-Lucent 1665 DMX node, verify/install the required low-speed OLIU circuit packs and/or pluggable transmission modules in the required Function/Growth slots being used for access.

At the extension, verify Main 1 is being used for access (Main 2 is unavailable in this application).

Important!

If you plan to use STS-1 tributaries 25-48 on slots A1, B1, or C1 of the host Alcatel-Lucent 1665 DMX node, then the LNW27, LNW29, LNW76, LNW202, LNW221–259 OC-48 or OC-192 circuit packs must be used in the MAIN slots. If the work instructions or office records do not specify OLIU types, refer to Alcatel-Lucent 1665 Data Multiplexer (DMX) Applications and Planning Guide, 365-372-300, for a description of OLIU circuit packs/pluggable transmission modules and applications. Optical line power measurements and/or office records must be used to verify that the span length can be supported.

The companion Function/Growth slot at the host Alcatel-Lucent 1665 DMX nodes may be:

  • unequipped (no circuit pack installed)

  • equipped with a protection OLIU circuit pack and companion port with no cable connected

  • equipped with a protection OLIU circuit pack and the companion socket is unequipped.

  • equipped with a different type 0x1 compatible circuit pack (when Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs are in the Main slots)

  • equipped with the same type 0x1 compatible circuit pack and the companion port is used for a different 0x1 application (when Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs are in the Main slots)

Important!

If OSI over DCC is enabled for ports, an inconsistent DCC values alarm is reported when the ports are looped back.

If required at the host Alcatel-Lucent 1665 DMX node, clear the inconsistent DCC values alarm by disabling OSI over DCC for the required ports. From the System View menu, select Configuration → DCC Terminations and disable OSI Over DCC for the required DCC ports.

Reference:

Procedure 6-4: Provision DCC terminations

6

Important!

If the Main slots are equipped with Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs, provision the port Application parameter to 0x1 (recommended) or UPSR at the host node for this application.

If the Main slots are not equipped with Very Large Fabric LNW59, LNW82, or LNW504 OLIU circuit packs, provision the port Application parameter to UPSR or 0x1S1 at the host node for this application.

From the System View menu at the host Alcatel-Lucent 1665 DMX node, select Configuration → Equipment, select the required port, and provision port parameters as required from your work instruction.

Procedure 4-4: Provision OLIU circuit packs/ports for service

7

At the host Alcatel-Lucent 1665 DMX node, verify that the low-speed OC-n ports were provisioned correctly using the View → Equipment command.

8

Important!

If OSI over DCC is enabled, the LAPD Role parameter must be provisioned differently at each end of an optical span. For example, if the LAPD Role parameter is provisioned to user-side at one end of an optical span, then the LAPD Role parameter must be provisioned network-side at the other end of the optical span.

From the System View menu, select Configuration → DCC Terminations and provision the DCC terminations for the required DCC ports according to the work instructions.

Result:

If OSI over DCC is enabled, an inconsistent DCC values alarm will occur if the OC-n ports are looped back.

Reference:

Procedure 6-4: Provision DCC terminations

9

From the System View menu at the host Alcatel-Lucent 1665 DMX node, select View → DCC Terminations and verify that the DCC terminations were provisioned correctly.

10

At the far-end node that is connecting to the host Alcatel-Lucent 1665 DMX node, provision the required ports, DCC terminations, synchronization, and remote NE status functions according to the work instructions.

Refer to the other product's documentation to perform the required provisioning.

11

Connect the optical fibers and verify the integrity of the optical span being installed.

Procedure 14-4: Perform connection and verification of optical facility

12

Perform end-to-end optical line test.

Reference:

Procedure 14-8: Perform end-to-end optical line test on Function OLIUs

13

Click the Alarm List button and verify that no alarms are present.

Important!

Establishing service requires that the proper slots in each terminating node be properly equipped with the correct circuit pack(s) for the type of service being established. It also requires numerous cross-connections in each of the nodes representing the path of the required service. Additionally, transmission tests should be performed to verify the continuity and quality of the established circuit.

The 0x1 unprotected optical extension is now ready for initial service to be established.
