UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002
10-1937 555-233-123
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.

Result Description/Recommendation
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.
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 has no affect on the test results.
4. A list config command shows that the circuit pack and the
ports are properly installed.
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.
2012 ABORT Internal system error.
1. Retry the command at 1-minute intervals for a maximum of 5
times.
