Important!

There are two 1+1 configurations: Unidirectional 1+1 (referred to as 1+1) and Bidirectional 1+1.

The port Application parameter must be provisioned 1+1 at both ends of the system or Bidirectional 1+1 at both ends of the system. Bidirectional 1+1 is required when interworking with other vendor's equipment that does not bridge DCC traffic on the active and standby lines. (Alcatel-Lucent 1665 DMXtend supports bridging DCC traffic on the active and standby lines.)

Alcatel-Lucent 1665 DMXplore does not support Bidirectional 1+1.

From the System View menu at the near-end node, select Configuration → Equipment to access the Main 1 and 2 ports and provision the port parameters according to the work instructions.

Reference:

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

Important!

The port Application parameter may be changed from 1+1 to 1+1 Bidirectional or from 1+1 Bidirectional to 1+1 when cross-connections exist on the line pair.

Select View → Equipment to access the Main 1 and 2 ports and verify that the ports were provisioned correctly.

From the System View menu, select Configuration → Equipment. Select Alcatel-Lucent 1665 DMXtend (AID=system), then click Select at the bottom of the window.

If required, provision the 1+1 Protection Priority parameter (unidirectional 1+1 applications only). Click Apply if changes were made, then click Yes to the warning message to make your changes. Click Close to exit.

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 DCC port dcc-m-1 according to the work instructions.

Reference:

Procedure 6-4: Provision DCC terminations

From the System View menu, select View → DCC Terminations, verify that the DCC terminations were provisioned correctly and click Close.

Important!

Synchronization Autoreconfiguration is only provisionable if the system Timing Mode parameter is Line and the Sync Messaging parameter of all ports is enabled. If the Sync Messaging parameter is enabled at any port in the network, it must be enabled at all ports in the network.

If required, provision the synchronization functions (for example, timing mode) according to work instructions.

Reference:

Procedure 6-5: Network Element synchronization provisioning

Important!

If Remote NE Status is to be used, at least one network element must be provisioned as the Alarm Gateway Network Element (AGNE) in the network. If the network element is designated as the Alarm Gateway Network Element (AGNE), the Alarm Gateway parameter must be provisioned Enabled.

From the System View menu, select Administration → Set NE, provision the Remote NE Status, Alarm Group, and Alarm Gateway parameters according to the work instructions, and click OK.

Result:

A dialog box appears asking you to confirm executing this command. Click Yes.

Reference:

Procedure 7-9: Set NE defaults — alarm gateway, alarm group, remote NE status, FTP/FTTD, security and history log thresholds

At the far-end node, provision the Main ports, DCC terminations, synchronization, and Remote NE Status functions according to the work instructions.

Important!

The near-end circuit pack in the Main 1 slot must be connected to the far-end circuit pack in the Main 1 slot, and the near-end circuit pack in the Main 2 slot must be connected to the far-end circuit pack in the Main 2 slot. Refer to the 1+1 linear worksheet.

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

Procedure 14-7: Perform end-to-end optical line test on Main OLIUs

At each node in the 1+1 linear network, click the Alarm List button and verify that no alarms are present. If required, clear any alarms that 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 1+1 linear network is now ready for initial service to be established.
