q. Error Type 2561: ATM-EI 2-way Transmission Failure (circuit pack is having
problems creating connections to other port networks in the system).
1. Test the ATM-EI circuit pack (
test board UUCSS
).
2. Follow the repair procedures suggested for Test #241.
r. Error Type 2817, 2818: 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: 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 PKT-BUS errors, if any. The probability of this error being
related to Packet bus problem increases with the number of other
circuit packs using the Packet bus that are also displaying 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.
