TBRI-PT (ISDN Trunk-Side BRI Port)
BRI Port Local TDM Loop-Around Test (#619)
This test is conditionally destructive.
This test verifies the connectivity of a BRI port across the TDM bus. It aborts if
calls associated with the port are in progress. Failure of this test indicates an
on-board fault associated with the port hardware on the circuit pack.
This Loop-Around test runs the following individual tests on the two B channels
(B1 and B2) associated with the port:
A Loop-Around test across the TDM bus for B1.
A Conference Circuit test for B1.
A Loop-around test across the TDM bus for B2.
A Conference Circuit test for B2.
The tests are run in the above order. If one fails, the remaining tests in the
sequence are not executed, and maintenance software returns an error code.

Code Result Description / Recommendation
1000 ABORT The system resources required to run this test are not available. The port may
be busy with a valid call.
1. Use the display port UUCSSpp command to determine the trunk
2. If the port is idle, then retry the command at 1-minute intervals up to 5
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 the system has no TDM-BUS errors and is not handling heavy traffic,
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 up to 5 times.

group/member number of the port. Use the status bri-port UUCSSpp
command to determine the service state of the port. If the service state
indicates that the port is in use, then the port is unavailable for certain
tests. Wait until the port is idle before retesting.
