DEFINITY ECS Release 8.2 Maintenance for R8.2csi
555-233-119 Issue 1
April 2000
Maintenance Objects
3-150ATM-EI (Expansion Interface Circuit Pack)
3
1. Either remove the wrong circuit pack and insert the ATM-EI circuit
pack or remove the ATM-EI administration (see ‘‘Basic ATM PNC
administration’’).
2. Remove the ATM-INTF administration and re-administer the slot
(
change circuit-pack
) to match the circuit-pack that is physically
present in this slot.
e. Error Type 131: an ATM-EI circuit pack has been removed from the slot for
5 minutes.
1. Insert the ATM-EI circuit pack into its administered slot.
2. Another way to resolve or prevent this alarm is to remove the
ATM-EI administration (see ‘‘Basic ATM PNC administration’’
), then
remove the ATM-INTF administration (
change circuit-pack
).
It is possible that the ATM-EI could be held in reset by the EPN
Maintenance board and is not inserted in the system.
1. Try issuing the
test maint P long
command on the maintenance
board in the same port network.
f. Error Type 257: Expansion Interface Control Channel Test #316 failed
(board cannot communicate on the TDM bus control channel). Follow the
suggested test procedures.
Error Type 258: The archangel is out of sequence (Aux Data indicates
angel number).
Error type 259: the expansion archangel link (EAL) to the active ATM-EI
board is down. See SYS-LINK.
g. Error Type 513: ATM Crosstalk test failed. The board is either writing to or
reading from a TDM time slot that is not allocated to the board.
1. Test the board (
test board UUCSS
) and follow the test procedures
suggested for this test. In random tests of a single DSP during low
or high traffic, the same DSP may be tested more than once.
h. Error Type 769 and 770 (Error Type 771 below): board-degraded alarm
errors that result when the ATM switch is sending corrupted cells or
excessive AAL/LAPD retransmissions (off-board ATM cell corruption
errors). These errors indicate the detection of a problem in handling ATM
cells that are received from the fiber interface.
