UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 June 2005 2447
1950 ABRT 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
using test ds1-loop location end-loopback/span-test in
order to execute this test.
2000 ABRT 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 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 effect on the test results.
4. A list config 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 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.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL UDS1 Interface circuit pack failed the DS1 Board Loopback test.
1. Retry test ds1-loop location ds1/csu-loopback-tests
2. If the BLB test continues to fail, then replace the UDS1 circuit pack.
PASS The BLB test executed successfully. The test pattern was transmitted and
received successfully up to the DS1 board edge.
