Yellow F5 Fault Alarm
For 32-channel E1 operation with CRC4 on, the F5 fault state is defined as a fault in the
user-network interface, specifically in the direction from the user (PBX) to the network. Refer to
CCITT recommendation I.431.

ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
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 Test #138 #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.
