call.
Aux Data 57487—PBX could not get "loop close" signal.
The DS1 Interface circuit pack detected a hardware fault. These errors will
cause Dial Tone Test #314 to run and are only considered a problem if the
Dial Tone test fails (in which case Error Type 1025 will also show up). In

"disconnected" by the status command), which allows only incoming calls.
Run Dial Tone Test #314, and follow the procedures.

hardware malfunction. Run short test sequence, and investigate
associated errors (if any).

out-of-service state. No calls can be made on this trunk except Facility
Access Test Calls. For details on this feature, see
section in
