Maintenance-Object Repair Procedures
k. A critical failure has been detected in the packet-bus interface of the circuit
pack. This failure may be due to either a packet-bus or to an on-board
fault. If the packet bus is alarmed, see
8-1230
Chapter 5 for recommended repair procedures. The probability of this
error being related to packet-bus problems increases with the number of
ISDN-BRI circuit packs displaying this error.
If the packet bus is not alarmed, reset the circuit pack via the busyout
board UUCSS and reset board UUCSS commands. If the Circuit Pack
Restart test (#594) passes, then the on-board circuitry is healthy. Retire
the alarm via the test board UUCSS long clear command. If the Circuit
Pack Restart test (#594) fails, replace the circuit pack. If the problem
persists after complying with the above instructions, then follow normal
escalation procedures.
l. These errors are not service-affecting. No action is required. These errors
are reported by the circuit pack when it receives a bad control channel
message from the switch. The auxiliary data identifies the following error
events:
m. This error is not service-affecting. No action is required.
3843
n. This error indicates that the circuit pack sent a large number of control
channel messages to the switch in a short period of time.

4096 Bad major heading
4097 Bad port number
4098 Bad data
4099 Bad sub-qualifier
4100 State inconsistency
4101 Inconsistent downlink message
Bad translation RAM detected, but call continues by using another
translation location.
If error type 1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity.
If error type 1538 absent, then the circuit pack was not taken
out-of-service, but has generated 50% of the messages necessary
to be considered hyperactive. This may be normal during heavy
traffic periods. If traffic is light, it may indicate a problem with the
circuit pack or the equipment attached to it.
