interface. The test is highly destructive and can only be initiated by a system
technician-demanded reset board PCSS command.
All trunks on the DS1 Interface circuit pack must be busied out via the system
technician busy-out board command before running the Internal Looparound
Test. When the Internal Looparound Test is initiated, maintenance software
sends appropriate messages to the DS1 Interface circuit pack to start the test.
The test uses the Tone Generator and Tone Detector to exercise a bit pattern
consistency test for all ports. If the transmitted and received bit patterns on a
trunk are different, the test fails.
When the test is complete, the maintenance software sends a stop loop around
message to the DS1 Interface circuit pack to put the circuit pack back into the
normal operation mode. All trunks of the DS1 Interface circuit pack are restored
to the in-service state after the release board command is entered

Result Description/ Recommendation
2012 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
1002 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” to diagnose 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.
1003 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. Resolve any “TTR-LEV” errors in the Error Log.
2. Resolve any “TONE-PT” errors in the Error Log.
3. If neither condition exists, retry the test at 1-minute intervals a maximum
of 5 times.
1004 ABORT Received an incoming call on a port of the DS1 circuit pack during the test.
1. Enter the busy-out board PCSS command to put all trunks of DS1
Interface circuit pack to out-of-service state.
2. Retry the command at 1-minute intervals a maximum of 5 times.
1015 ABORT Ports on DS1 Interface circuit pack have not been busied out.
1. Enter the busy-out board PCSS command to put all trunks of the DS1
Interface circuit pack into out-of-service state.
2. Retry the command.
