interface. The test is highly destruc tive and can only be initi ated by a system
technician-demand ed reset board UUCSS command.
All trunks on the DS1 Interface circuit p ack must be busied out via the system
technician busy-out board command before running the Internal Loop around
Test. When the Internal Looparound Test is initiated, maintenance software sends
appropriate messag es to the DS1 Interface circuit pac k to start the test. The test
uses the Tone Generator and Tone Detector to exercise a bit pattern consistenc y
test for all ports. If the transmitted and received bit p atterns 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 circ uit pack to put the circ uit pack bac k into the
normal operation mode. All trunks of t he DS1 Interface circuit pac k are restored
to the in-service state after the release board command is entered

Error
Code Test
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.
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.
2. Resolve any TONE-PT errors.
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 UUCSS 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 UUCSS command to put all trunks of the DS1
Interface circuit pack into out-of-service state.
2. Retry the command.
