Table 1: Condition Details
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.

Clearing an OdtgMism Alarm
Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.
- 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.
- 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.
