Maintenance Object Repair Procedures
NOTE:
When the Expansion Interface circuit pack under test is an EPN, the data
packet must also pass through the Active Expansion Interface circuit packs
of the Active link connecting the EPN to the PPN.
This test requires the Expansion Interface circuit pack to ignore incoming data
from its neighbor Expansion Interface circuit pack on the opposite end of the fiber.
Thus, this test disturbs any inter-cabinet connections that currently exist and
disrupts signaling between the two cabinets.

ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5
times.
ABORT The system could not allocate time slots for the test. The
system may be under heavy traffic conditions or it may have
time slots out-of-service due to TDM-BUS errors. Refer to
TDM-BUS (TDM Bus) Maintenance documentation to
diagnose any active TDM-BUS errors.
1. If system has no TDM-BUS errors and is not handling
heavy traffic, repeat test at 1-minute intervals a maximum
of 5 times.
ABORT The system could not allocate a tone receiver for the test. The
system may be oversized for the number of Tone Detectors
present or some Tone Detectors may be out-of-service.
1. Look for TTR-LEV errors in the Hardware Error Log. If
present, refer to TTR-LEV (TTR Level) Maintenance
documentation. Even if there are no TTR-LEV errors,
there still may not be a Tone Detector available on the
network that contains the circuit pack being tested. Verify
that there is at least one Tone Detector on this network. If
there is not at least one Tone Detector, this test always
aborts for this Expansion Interface circuit pack. This does
not harm the system in any way.
2. Look for TONE-PT errors in the Hardware Error Log. If
present, refer to TONE-PT (Tone Generator) Maintenance
documentation.
3. If neither condition exists, retry the test at 1-minute
intervals a maximum of 5 times.
