TDM Bus Clock Slip Inquiry Test (#149)

This test evaluates the quality of the synchronization source for the IPSI circuit
pack's Tone-Clock circuit.
NOTE:
This test does not apply to the TN2182.

ABORT The system could not allocate the necessary resources for the test.
1001 ABORT The system could not allocate the necessary resources for the test.
1. Wait 1-minute, and retry the test.
2000 ABORT Response to the test request was not received within the allowable time period.
2100 ABORT System resources required to run this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
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 two sources:
1. A DS1 Interface circuit pack, if DS1 Synchronization is administered, and
2. The local oscillator on the IPSI's Tone-Clock circuit providing the EPN's
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
2. Otherwise, see
PASS The IPSI 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 circuit pack. The status synchronization
command should be used to verify that the desired synchronization reference is
providing timing for the system.
