2053 ABORT At least one of the following errors is found on the DS1
circuit pack: 1281—Loss of signal, 1793—Blue Alarm,
2049—Red Alarm, 2305—Yellow Alarm, 1537—
Hyperactivity.
Look for the above error types in the Hardware Error Log
and follow the procedures given in the appropriate
DS1-BD or UDS1-BD maintenance documentation for
the listed error types.
FAIL This can be due to on-board or off-board problems.
Off-board problems of concern include EXP-PN and
EXP-INTF faults, TDM-BUS faults, and faults associated
with the tone detectors/tone generators. Clear all
off-board problems before replacing the board. Keep in
mind that a TDM-BUS problem is usually the result of a
faulty board connected to the backplane or bent pins on
the backplane.
1. Look for EXP-PN and/or EXP-INTF errors in the error
log. If present, refer to the EXP-PN Maintenance
documentation and the EXP-INTF Maintenance
documentation.
2. Look for TDM-BUS errors in the error log. If present,
refer to the TDM-BUS Maintenance documentation.
3. Look for TONE-BD and/or TONE-PT errors in the
error log. If present, refer to the TONE-BD
Maintenance documentation and the TONE-PT
Maintenance documentation.
4. Retest when the faults from steps 1, 2, and 3 are
cleared. Replace the board only if the test fails.
PASS The port is correctly using its allocated time slots.
User-reported troubles on this port should be
investigated using other port tests and by examining
station, trunk, or external wiring.
