Result
Description / Recommendation
Any FAIL The Error Code represents the number of timing slips detected on the
incoming synchronization source since the last slip inquiry was sent to the
Tone-Clock circuit. The incoming synchronization signal can be from one
of the following sources:
1. A DS1 Interface circuit pack, if DS1 Synchronization is administered,
and associated with the circuit pack tested
2. S8700-series Fiber-PNC: A Stratum-3 clock, if that option is
administered and the circuit pack tested was the active Tone-Clock in
the PN 1.
3. S8700-series Fiber-PNC: The local oscillator on the master IPSI’s
Tone-Clock circuit or on the master Tone-Clock circuit pack, if it is
providing the PN’s clocking signals
4. S8700-series IP-PNC: The local oscillator on the IPSI’s Tone-Clock
circuit providing the media gateway’s clocking signals
5. S8700-series Fiber-PNC: An EXP-INTF circuit pack, if the PN on which
the test was executed does not contain the system’s current
synchronization reference
The Error Code is a value between 1 and 255.
1. Small numbers of slips should not result in service degradation. If the
Error Code is small (1 or 2), rerun the test. If the error only occurs
infrequently, it may be ignored.
2. Otherwise, see Synchronization Troubleshooting in SYNC (Port
Network Synchronization).
PASS The IPSI or Processor/Tone-Clock circuit pack does not detect any timing
slips. This indicates that the incoming synchronization timing source is valid
or that the system’s synchronization reference is an IPSI or Processor/
Tone-Clock circuit pack. Enter status synchronization to verify that
the desired synchronization reference is providing timing for the system.
TDM Bus Clock PPM Inquiry Test (#150)
This test evaluates the quality of the synchronization source for the Tone-Clock circuit.
