How to Configure the Dual Feed and Selective Receiving Boards

How to configure the dual feed and selective receiving boards in the case of a unidirectional WDM link.

Fault Type

Optical Transponder Unit

Symptom

The LDG board that supports the dual fed and selective receiving is used as the service board. This case also applies to the OTU board hat supports the dual fed and selective receiving.
When the link is not configured with protection and the fiber signal flow is not created on the T2000, the T2000 display that the WDM-side optical interfaces adopt two separated routes.

Cause Analysis

In the case of the board that supports the dual fed and selective receiving, if the physical fibers are not connected and the logic fibers are not created on the T2000, the system cannot identify whether the link is configured with protection.
To make the system report the correct WDM-side optical interface information (that is, the link does not adopt the intra-board 1+1 protection) of the LDG board, the use status of the unused WDM-side optical interfaces must be set to Unused.

Procedure

  1. In the NE Explorer, select the desired board, and choose the Configuration > WDM Interface.
  2. In Basic Attributes, select the Path Used Status field, and set the use status of the WDM-side optical interfaces to Unused.
