    Table 1: Condition Details

    Parameter

    Description

    Code

    odtgMism

    Description/Cause

    ODTG Mismatch: The ODU Data Tributary Group (ODTG) configuration on a multiplexed interface is inconsistent at the two ends of the fiber. This means that the ODU subinterface cross-connected at the local end does not match the ODU subinterface cross-connected at the far end.

    Entities Affected

    • OTN ODU interfaces (see table)

    Default Severity

    Critical

    Service Affecting

    Yes (true)

    Condition Clearing

    Clearing an OdtgMism Alarm

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

    1. Ensure that the interface endpoints at both ends of the fiber are configured for the same ODU subinterface. For information, see the BTI7800 Series Software Configuration Guide.
    2. Check for alarms on the local interface.
      • If the alarm clears, you have completed this procedure.
      • If the alarm does not clear, contact your next level of support.
