Maintenance-Object Repair Procedures

8-202 Issue 1 May 2002
r. Error Types 2817 and 2818 — A DSP test failure detected along the
circuit path of the ATM-EI circuit pack.
1. Test the ATM-EI circuit pack (test board UUCSS).
2. Follow the repair procedures suggested for Test #1258.
s. Error Type 3329 — The on-board LANHO chip is insane, possibly due to a
problem in packet-bus arbitration, the transmission line frame, or the circuit
pack itself. The circuit pack cannot talk to the packet bus.
If the packet bus is alarmed:
1. Resolve any PKT-BUS errors. The probability of this error being
related to a packet-bus problem increases with the number of other
circuit packs using the bus that are also showing this error.
If the packet bus is not alarmed:
1. Reset the circuit pack (reset board UUCSS).
2. If the problem persists, replace the ATM-EI circuit pack.
If the system has a duplicated PNC, and the in-line error received is from
an active ATM-EI, the system switches to the standby PNC.
!
CAUTION:
If the system does not have duplicated PNC, services to the EPN
could be disrupted.
t. Error Types 3585 and 3586 — (Major board alarm) A failure of critical
components involved in the operation of the circuit pack, and the switch
can no longer recognize the circuit pack. If the system has a duplicated
PNC and the in-line error received is from an active ATM-EI, the system
switches to standby PNC.
!
CAUTION:
If the system does not have duplicated PNC, services to the EPN
could be disrupted.
Error
Type Description Aux Data indicates
2817 DSP test failure The Aux Data field contains the following
information about the failed DSPs:
X is the number of talker DSPs
Y is the number of listener DSPs
Z is the number of echo-cancelling DSPs
2818 One or more DSPs failed DSP number that has failed
