q. Error Type 1313 — CPE Loopback Jack deactivation error. This error
occurs when the UDS1 circuit pack could not deactivate a CPE Loopback
Jack on power-up/reset or upon software request.
Attempt to clear the alarm using the commands busyout board UUCSS,
test ds1-loopback UUCSS end-loopback/span-test, release board
UUCSS. If the attempt to deactivate the CPE Loopback Jack continues to
fail, other steps must be taken to deactivate the loopback.
r. Error Type 1314 — Far CSU Loopback deactivation error. This error
occurs when the UDS1 circuit pack could not deactivate a far-end CSU
loopback on power-up/reset or upon software request.
Attempt to clear the alarm using the commands busyout board UUCSS,
test ds1-loop UUCSS end-loopback/span-test, release board UUCSS.
If the attempt to deactivate the Far CSU loopback continues to fail, then
escalate the problem.
s. Error Types 1400, 1401 — Echo Cancellation errors are logged when:
■
Error 1400 - Echo canceller function failed. The Echo Canceller
Function Test, which is executed by firmware, failed.
■
Error 1401 - Echo canceller memory failed. The Echo Canceller
Memory Test, which is executed by firmware, failed.
Echo Cancellation is no longer being supplied by the board. Clear the
alarm using the following commands: busyout board UUCSS, test board
UUCSS long, release board UUCSS. If Test #1420 (Echo Canceler Test)
fails, replace the circuit pack.
t. Error type 1537 — LAN Bus Timeout Error. This error occurs when the
circuit pack transmits too many bytes on the LAN bus for a single frame.
This condition may be caused by an on-board fault or by 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 three times within 10 minutes, the board is isolated from
the Packet Bus and the board alarmed. To clear the alarm and restore the
board to the Packet Bus, use the 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 circuit pack.
