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.

: A Stratum-3 clock, if that option is administered and the 

circuit pack tested was the active Tone-Clock in the PN 1.

3.

: 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.

: The local oscillator on the IPSI’s Tone-Clock circuit providing 

the media gateway’s clocking signals

5.

: 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 variable amount ranging from 1 to 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 

on page 2143 of this manual.

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. Use status synchronization to verify that the 

desired synchronization reference is providing timing for the system.
