UDS1-BD (UDS1 Interface Circuit Pack)
Echo Canceller Test (#1420)
This test is destructive.
NOTE:
This test is executed only for TN464GP/TN2464BP circuit packs that have
been administered on the DS1 circuit pack form to provide echo
cancellation. The TN464GP/TN2464BP must be busied out before this
demand test is run.
This test is for the TN464GP and TN2464BP circuit packs. The test originates
from a manually initiated test board long demand test of a TN464GP/TN2464BP
circuit pack. The test instructs firmware to test the echo cancellation circuity. The
TN464GP/TN2464BP firmware tests echo cancellation on a subset of channels. If
any channel fails twice, or if any two channels fail once, the test fails, and echo
cancellation is bypassed on all channels of the board. Otherwise the test passes,
and echo cancellation is configured to the administered parameters.

Error Test
Code Result
1015 ABORT The board is not busied out. This test will abort if the UDS1 circuit pack under
test is in service.
2000 ABORT Response to the test was not received within the allowable time period. This
may be due to hyperactivity. Error Type 1538 in the error log indicates
hyperactivity. The hyperactive circuit pack is out of service and one or more of
the following symptoms may be exhibited.
When hyperactivity occurs, the circuit pack is isolated from the system, and
all of the trunks for this circuit pack are placed into the out of service state.
The system will try to restore the circuit pack within 15 minutes. When no
faults are detected for 15 minutes, the UDS1 interface circuit pack is restored
to normal operation. All of the trunks for the UDS1 interface circuit pack are
then returned to the in service state. Hyperactivity is often caused by the
associated facility. In such a case, faults (such as slips, misframes, or blue
alarms) would be entered in the error log. In addition, many hardware errors
would be logged against the associated trunk circuits. If the facility is OK and
the error occurs again after 15 minutes, replace the circuit pack.

Description/ Recommendation
1. The UDS1-BD tests (such as Test #138 and Test #139) are aborting with
error code 2000.
2. The tests run on the ports of this circuit pack are returning a no board
result.
3. A busyout or a release command has no affect on the test results.
4. A list config command shows that the circuit pack and the ports are
properly installed.
