DS1-BD (DS1 Interface Circuit Pack)
Issue 1 May 2002 8-635 555-233-143
1950 ABORT Another loop-back/span test is already executing on the DS1 board or the
board is in a network requested loop-back mode (Line loop back or Payload
loop back). 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 loop-back or payload loop-back mode. Only one
long-duration loop-back/span test can be active at a given time. Thus, if a
loop-back/span test is already active, that test must be deactivated via the test
ds1-loop UUCSS end-loopback/span-test command in order to execute this
test.
1951 ABORT The CSU Equipment Loopback test could not be executed because the 120A
CSU module/T1 sync splitter was not physically installed. Physically connect
the 120A CSU module/T1 sync splitter to the TN767E board behind the port
carrier.
ABORT Internal system error
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
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 DS1-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.
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 DS1 interface circuit pack is restored to
normal operation. Every DS1 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, escalate this problem.
