Verify normal service level; first, switch the active clock to standby using:
LD 60

If an error message results, refer to Avaya Communication Server 1000M and
Meridian 1 Large System Maintenance (NN43021-700) for the interpretation.
Note:
Switching clock controllers using LD 60 will generate ERR20 messages.
These can usually be ignored, but avoid excessive switching, especially when
counters are near the maintenance or out-of-service thresholds. Excessive
switching can generate maintenance or out-of-service threshold messages, or
cause the PRI to be disabled.
Check the counters in LD 60. If necessary, reset the counters using the RCNT
command.
