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.
ANY FAIL The test failed. 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 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 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.
