Attempt to clear the alarm via the follo wing commands:
busyout board
UUCSS
,
test ds1-loopback UUCSS end-loopback/span-test
,
release
board UUCSS
. If the attempt to deactivate the CPE Loopb ack Jack
continues to fail, other steps must b e taken to deactivate the loop back.
r. Far CSU Loopback deactivation error. This error occurs when the TN464F
circuit pack c ould not deac tivate a far-end CSU loopback on
power-up/reset or upon software request.
Attempt to clear the alarm via the follo wing commands:
busyout board
UUCSS
,
test ds1-loop UUCSS end-loopb ack/span-test
,
release board
UUCSS
. If the attempt to deactivate the Far CSU loopback continues to
fail, then escalate the problem.
s. LAN Bus Timeout Error. This error occurs when the circuit p ack transmits
too many bytes on the LAN bus for a sing le frame. This condition may b e
caused by an on-bo ard fault or by faulty data received on one of the circuit
pack’s external por ts. If any of the ports on this c ircuit pack are alarmed ,
refer to the repair procedu res for those maintenance objec ts.
If the error occurs three times within 10 minutes, the board will b e isolated
from the Packet Bus and the board will b e alarmed. To clear the alarm and
restore the board to the Packet Bus, use the following commands:
busyout board UUCSS, reset board UUCSS, test board UUCSS long,
release board UUCSS.
If the problem persists, and there are no PKT-BUS alarms or port alarms,
then replace the circu it pack.
t. The hyperactive circuit pack is out-of-servic e and may exhibit one or mo re
of the following symptoms:
1. The common circuit pac k level tests such as Test #50 and/or Test
#52 are aborting with error cod e 2000.
2. The tests run on the ports of this circuit p ack are returning with a
NO-BOARD.
3. A busyout/release of the circuit p ack has no affect on test results.
4. A list configuration command shows that the circ uit pack and
ports are properly insta lled.
The circuit pack is isolated from the system and all trunks or por ts on this
circuit pack are placed into the out-of-servi ce state. The system will try to
restore the circuit pack within 20-30 minutes. When no faults are detected
for 20-30 minutes, the UDS1 Interface circuit p ack is restored to normal
operation. All trunks or ports of the UDS1 Interfac e circuit pac k are then
returned to the in-service state. If the b oard is not restored to normal
operation, or the error recurs after the board was restored to normal
operation, escalate the prob lem.
u. For later releases of G3V4 and beyond, only error 3073 will sh ow that this
board is receiving slips and the AUX data shows the last s lip count that
was reported.
