MAPD-BD (MAPD Interface Circuit Pack TN802)
Issue 5 October 2002
1361
555-233-119
k. Error Type 1537: LAN Bus Timeout; the circuit pack transmitted too many
bytes on the LAN bus for a single frame. This condition may be caused by:
■
an on-board fault
■
faulty data received on one of the circuit pack’s external ports. If any
of the ports on this circuit pack are alarmed, refer to the repair
procedures for those maintenance objects.
If the error occurs 3 times within 10 minutes, the system raises the board
alarm and isolates it from the Packet Bus.
1. Clear the alarm and restore the board to the Packet Bus using the
following command sequence:
a. busyout board UUCSS
b. reset board UUCSS
c. test board UUCSS long clear
d. release board UUCSS
2. If the problem persists, and there are no PKT-BUS alarms or port
alarms, then replace the circuit pack. See ‘‘Shutting down NT on the
TN802’’ before removing the circuit pack.
l. Error Type 1538: hyperactive circuit pack is out-of-service and may exhibit
one or more of the following symptoms:
■
The common circuit pack tests (for example, Test #50 and/or Test
#52) abort with Error Code 2000.
■
Port tests on this circuit pack return NO-BOARD.
■
A busyout/release of the circuit pack has no affect on test results.
■
A list configuration command shows that the circuit pack and ports
are properly installed.
The circuit pack is isolated from the system and all trunks or ports on this
circuit pack are placed into the out-of-service state. The system attempts to
restore the circuit pack within 20-30 minutes. When no faults are detected
for 20-30 minutes, the MAPD Interface circuit pack is restored to normal
operation and all trunks or ports on the MAPD Interface circuit pack return
to the in-service state.
1. If the board is not restored to normal operation, or the error recurs
after the board is restored to normal operation, escalate the
problem.
m. Error Type 3073 - 3160: board is reporting slip errors. Aux Data shows the
last reported slip count.
