BRI-BD/LGATE-BD (ISDN-BRI Line Circuit Pack)
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 fault or an on-board
fault. If the Packet Bus is alarmed, refer to the "PKT-BUS (Packet Bus)"
section and Chapter 9, "Packet Bus Fault Isolation and Correction" 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 PCSS and reset board PCSS commands. If the Circuit Pack
Restart Test (#594) passes, then the on-board circuitry is healthy. Retire
the alarm via the test board PCSS 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. Error type 3999
control channel messages to the switch within a short period of time. If
error type 1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity. If error type 1538 is not present, then
the circuit pack has not been taken out-of-service, but it has generated
50% of the messages necessary to be considered hyperactive. This may
be completely normal during heavy traffic periods. However, if this error
type is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.
