UDS1-BD (UDS1 Interface Circuit Pack)
Table 8-535. Test #1209 DS1 Board Loop-Back Test — Continued
Error Test
Code Result Description / Recommendation
1039 ABORT The UDS1 Interface circuit pack is providing timing for the system. Executing
this test could cause major system disruption.
If the UDS1 Interface circuit pack needs to be tested, set the synchronization
reference to another DS1 Interface circuit pack or to the IPSI circuit pack via
the following command sequence:
1. Issue the disable synchronization-switch command.
2. Next, issue the set synchronization UUCSS command.
3. Lastly, issue the enable synchronization-switch command.
1950 ABORT Another loopback/span test is already executing on the DS1 board or the board
is in a network-requested loop-back mode (line loopback or payload loopback).
The hardware error log will indicate whether a Customer Loop-Back Jack test,
Far CSU Loopback test, or the One-Way Span test is executing or if the board
is in line-loopback or payload-loop-back mode. Only one long-duration
loopback/span test can be active at a given time. Thus, if a loopback/span test
is already active, that test must be terminated via the test ds1-loop UUCSS
end-loopback/span-test command in order to execute this test.
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 Tests #138 and #139) are aborting with error
2. The tests run on the ports of this circuit pack are returning a no-board
3. A busyout or a release command has no effect on the test results.
4. A list config command shows that the circuit pack and the ports are

properly installed.
NOTE:
When hyperactivity occurs, the circuit pack is isolated from the system,
and all of its trunks 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. Every UDS1 interface trunk is 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.
