1020 ABORT The test did not run because of a previously existing error on the specific port
or a more general circuit pack error.
1. Examine the Error Log for existing errors against this port or the circuit
pack and attempt to diagnose the already existing error.
2000 ABORT Response to the test request was not received within the allowable time period.
2100 ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
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 either on- 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 every off-board
problem 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. Resolve any EXP-PN and/or EXP-INTF errors.
2. Resolve any TDM-BUS errors.
3. Resolve any TONE-BD and/or TONE-PT errors.
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.
