5.Standard system:—Error 2305:
■ Replace the Expansion Interface circuit pack in this port
network and the Expansion Interface circuit pack in the PPN
that is connected to this port network.
■ If the problem persists, replace the Tone-Clock circuit pack
in the slave port network. Follow the steps listed in
“TDM-CLK” to replace the Tone-Clock circuit pack.
i. 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 WARNING alarm is first raised for 15 to 20 minutes before
the alarm is upgraded to a MAJOR or MINOR alarm.
