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, replace the circuit pack.
FAIL DS1 Interface circuit pack detects a Loss of Signal alarm. The physical link is
broken or the remote DS1 endpoint is down. All trunks or ports of this DS1
interface circuit pack are out-of-service. If the DS1 Interface circuit pack is
designated as the supplier of the system synchronization source, then the
system synchronization maintenance will adopt a source elsewhere. Refer to
"SYNC (Synchronization)" section for details.
1. If the DS1 Interface circuit pack connects to a T1 facility, call the vendor
of the T1 carrier to diagnose the remote DS1 endpoint. If the DS1
Interface circuit pack connects directly to a switch, call the system
technician of the remote switch to diagnose the DS1 endpoint.
2. Check the physical connection of the DS1 Interface circuit pack and the
cable. If a 120A1 CSU Module is physically connected to a TN767E board
on the back of the port carrier, check the physical connection of the CSU
Module and make sure the Network Interface cable is plugged into the
CSU Module’s NETWORK jack.
