q. Error Type 1313: CPE Loop-Back Jack deactivation error. This error occurs when the 

UDS1 circuit pack could not deactivate a CPE Loop-Back Jack on power-up/reset or upon 
software request.

Try to clear the alarm using busyout board location, test ds1-loop location 
end-loopback/span-test, and release board location. If the attempt to 

deactivate the CPE Loop-Back 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 loop back on power-up/reset or upon 
software request.

Try to clear the alarm using busyout board location, test ds1-loop location 
end-loopback/span-test, and release board location. If the attempt to 

deactivate the Far CSU loop back continues to fail, 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 location, test board location long, and 
release board location. 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 is alarmed. To clear the alarm and restore the board to the Packet bus, use 
busyout board location, reset board location, test board location 
long, and release board location.
If the problem persists, and there are no PKT-BUS alarms or port alarms, then replace the 
circuit pack.

u. Error Type 1538: the hyperactive circuit pack is out-of-service and may exhibit one or more 

of the following symptoms:

●

The common circuit pack level tests such as Test #50 and/or Test #52 abort with Error 
Code 2000.

●

The tests run on the ports of this circuit pack return a NO-BOARD result.

●

A busyout/release of the circuit pack has no effect on test results.

●

A list configuration command shows that the circuit pack and ports are properly 

installed.
