DS1-BD (DS1 Interface Circuit Pack)
Issue 5 October 2002
1121
555-233-119
1950 ABORT Another loopback/span test is already executing on the DS1 board or the
board is in a network requested loopback mode (Line loopback or Payload
loopback). The hardware error log will indicate whether a Customer
Loopback Jack Test, Far CSU Loopback Test, or the One-Way Span Test is
executing or if the board is in line loopback or payload loopback 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.
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 on the
back of 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 a maximum of 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 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 DS1 interface
circuit pack is restored to normal operation. All of the trunks for the
DS1 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, escalate this problem.
