Use the WaveStar^® CIT to log in to one of the host nodes being used for dual homing.

Reference:

Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar^® CIT session

Refer to Figure 10-8, Dual-Homed Alcatel-Lucent 1665 DMXtend ring example for an example of a dual-homed Alcatel-Lucent 1665 DMXtend ring configuration.

Important!

If a drawing of the network is not provided with the work instructions, it is recommended that you draw a simple diagram of the ring (indicating node-to-node connections) and list each node's TID.

On the System View menu, select Administration → OSI Routing Map and/or Administration → OSI Neighbor Map to retrieve a node-to-node listing of every node on the backbone ring.

Result:

The OSI Routing Map or OSI Neighbor Map window opens.

Verify that the ring configuration, Alcatel-Lucent 1665 DMXtend nodes, terminating nodes, and pass-through nodes are the same as specified in the work instructions.

Important!

All differences between the work instructions and the actual ring configuration must be resolved before continuing.

One at a time, use the WaveStar^® CIT to log in to each Alcatel-Lucent 1665 DMXtend node. From the System View menu at each node, select View → Equipment.

Result:

The View Equipment window opens.

Find the circuit pack, port, and/or tributaries being used for this service. Select the entity to view, then click the Select button at the bottom of the window. View the provisioning details for the selected entity and verify the entities are properly provisioned.

Use product documentation for non Alcatel-Lucent 1665 DMXtend nodes in the network to verify proper circuit pack/port provisioning details.

If the entities are not provisioned properly, use the procedures in this document to provision the Alcatel-Lucent 1665 DMXtend circuit packs/ports for service.

Important!

Cross-connections supporting DS3 services are STS-1 cross-connections. Cross-connections supporting DS1 services may be either STS-1 or VT1.5 cross-connections. Use VT1.5 cross-connections for DS1 services if you expect to cross connect only a portion of the VT1.5 signals in the STS-1 channel or if the VT1.5s are coming from different places. If STS-1 cross-connections are made at a shelf, there is a fixed mapping of all 28 VT1.5 cross-connections to a specific shelf group.

From your work instructions, determine the type of cross-connections to be made at each node for the service being established.

Refer to Dual-homed cross-connection example (UPSR port application) and Dual-homed cross-connections example (0x1S1 and 0x1S2 or 0x1 port application) at the end of this procedure.

Starting at one of the host nodes for the circuit being established, select View → Cross-Connections from the System View menu at each node in the ring to verify that the cross-connections specified on the work instructions may be made. If cross-connections are already assigned or improperly assigned, refer trouble to the provisioning organization. Improperly assigned cross-connections may have to be deleted, or a different timeslot must be selected for the service being selected.

Select Configuration → Cross-Connections from the System View menu to start the Cross-Connection Wizard. Use the Cross-Connection Wizard at all non terminating nodes in the network to provision pass-through cross-connections.

Use the Cross-Connection Wizard at the host nodes to make the proper cross-connections. (Select Configuration → Cross-Connections from the System View menu to start the Cross-Connection Wizard).

Use the Cross-Connection Wizard at the terminating (add/drop) nodes of the circuit being established to make the terminating cross-connections. (Select Configuration → Cross-Connections from the System View menu to start the Cross-Connection Wizard).

From the System View menu, select View → Cross-Connections at each node to verify that the proper connection has been made.

After all cross-connections have been made, verify that the channels have gone in service at each terminating node. From the System View menu at each terminating node, select View → Equipment.

Result:

The View Equipment window opens.

The provisioned cross-connections create connections to both sides of the ring. However, for unswitched STS cross-connections there are no channel states. For unswitched VT cross-connections there is an STS channel state (for the terminated STS). The channel state will transition once a good signal is received on either side of the ring. There will be channel states on the tributaries of the 0x1Sn interface.

Expand the details for the circuit pack being used. Select the required port, then click Select at the bottom of the window. Verify the port AID is correct at the top of the parameter display.

Under Port Data/Fault in the parameter display, verify the Port Monitoring Mode is IS (in service). If the Port Monitoring Mode is IS, then Stop, you have completed this procedure. Otherwise, perform one of the following:

• If the Port Monitoring Mode is NMON (Not Monitored),

  Perform the following:

  1. Click Close to exit this window. From the System View menu, select Configuration → Equipment. Expand the details for the circuit pack being used, select the required port and then click Select at the bottom of the window.

  2. Under the Fault Management section, select AUTO (Automatic) for the Port Monitoring Mode.

  3. Click Apply at the bottom of the window.

  4. Click Close to exit the window, then repeat this procedure from Step 15.

• If the Port Monitoring Mode is AUTO:

  Check the connections at the local cross-connect panel (or equivalent connection point).
