TONE-BD (Tone-Clock Circuit Pack)
Issue 4 May 2002
10-1793
555-233-123
Notes:
a. Error Type 1
This error indicates the circuit pack totally stopped
functioning or it was physically removed from the system.
NOTE:
The alarm is logged approximately 11 minutes after the circuit pack is
removed/SAKI Sanity Test (#53) fails.
If the circuit pack is not present in the system, insert a circuit pack in the
slot indicated by the error to resolve the error.
If the circuit pack is present in the system, it is faulty and must be replaced.
See the preceding section,
‘‘How to Replace a Tone-Clock Circuit Pack’’
If the faulty circuit pack is in standby mode, a MINOR alarm is raised, but
no other system action is taken. If the circuit pack is the active Tone-Clock,
further effects of this error depend on the Reliability Option for the switch.
If an interchange is attempted and the system is unable to activate the
standby Tone-Clock, Emergency Transfer is activated. If the problem is in
the PPN the entire system is affected. Otherwise only the EPN in question
is affected. When this happens, both circuit packs are faulty and must be
replaced. See the preceding section,
If a successful interchange occurs in response to a failure of the active
Tone-Clock, or if a standby Tone-Clock fails, the faulty Tone-Clock should
be replaced.
b. Error Type 18
The indicated Tone-Clock circuit pack has been made
unavailable via the busyout tone-clock PC command. This error applies
only to High or Critical Reliability systems (an active Tone-Clock may not
be busied out). To resolve this error, execute release tone-clock PC.
c. Error Type 23
The circuit pack has been logically administered but not
physically installed. Installing the circuit pack will resolve the alarm.
