SYNC (Port Network Synchronization)
● If the system’s 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.
If the primary synchronization reference is providing the system’s timing, check the
synchronization references administered, and follow the steps outlined in note (b).
If the secondary reference is providing timing, follow note (d).
● If the slave Tone-Clock circuit pack fails TDM Bus Clock Test #150 but the master
Tone-Clock does not fail this test, the master Tone-Clock circuit pack must be
replaced. Follow the Tone-Clock replacement steps listed in TDM-CLK (TDM Bus
Clock).
● Replace the active Expansion Interface circuit pack in the master port network.
● In a CSS configuration, replace the Switch Node Interface circuit pack connected
to the active Expansion Interface circuit pack in the master port network. Use list
fiber-link to determine the Switch Node Interface circuit pack that is
connected to the active Expansion Interface circuit pack in the master port
network.
● If the problem persists and any slip errors remain, follow the procedures described
in the troubleshooting section above.
It may take up to one hour to clear the alarm after the problem has been resolved.
i. Noise on the DS1 line can cause transient alarms on synchronization. Therefore, when a
sync problem occurs on Error Types 1, 257, or 513, a WRN alarm is first raised for 15 to 20
minutes before the alarm is upgraded to a MINOR or MAJOR alarm.
