    Table 1: Alarm Details

    Parameter

    Description

    Code

    tim

    Description

    Trace Identifier Mismatch: The received trace identifier is different from the expected trace identifier.

    Entities Affected

    • OTN OTU interfaces (see respective table below).
    • SONET/SDH interfaces (see respective table below).

    Possible Causes

    • The optical fiber link is from the wrong source (misconnected).
    • Either the expected trace identifier configured on the local interface is incorrect, or the trace identifier configured on the remote interface is incorrect.

    Default Severity

    Critical

    Service Affecting

    No (false).

    Clearing a TIM Alarm

    Note: Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

    1. Retrieve detailed interface data to view the values of the following attribute pairs:
      • OTU interface: Trace Message Expected / Trace Message Received
      • SONET/SDH interface: Expected Section Trace Message / Received Section Trace Message
      show interface name:identifier detail
    2. Based on the trace-message data, determine whether any of the following problems exist, and then resolve them:
      • The optical fiber link is from the wrong source (misconnected).
      • The expected trace identifier configured on the local interface is incorrect.
      • The trace identifier configured on the remote interface is incorrect.
    3. Check for alarms on the interface.
      • If the alarm clears, you have completed this procedure.
      • If the alarm does not clear, contact your next level of support.
