Demand test descriptions and error codes - Avaya Support

● If the system synchronization reference is a DS1 interface circuit pack and the
master Tone-Clock circuit pack fails TDM Bus Clock Test #150, the primary or
secondary (if administered) synchronization references are not providing valid
timing signals for the system. Check the system synchronization references
administered, and follow the steps outlined in note (a) if the primary
synchronization reference is providing timing for the system or note (c) if the
secondary synchronization reference is providing timing for the system.
● If the slave Tone-Clock circuit pack fails the TDM Bus Clock Test #150 but the
master Tone-Clock does not fail this test, the master Tone-Clock circuit pack must
be replaced.
If SLIP errors remain follow SLIP ANALYSIS.
3. Error 2305:
● If the problem persists, replace the Tone-Clock circuit pack in the slave port
network. Follow the steps listed in TDM-CLK (TDM Bus Clock) to replace the
Tone-Clock circuit pack.
g. Noise on the DS1 line can cause transient alarms on synchronization. Therefore, when a
synchronization problem occurs causing Error Types 1, 257, or 513, a WRN alarm is first
raised for 15 to 20 minutes before the alarm is upgraded to a MAJOR or MINOR alarm.
