DS1-BD (DS1 Interface Circuit Pack)
u. Error 3900 is used to give status information about a CPE Loopback Jack
test. The value in the Aux Data field indicates the status of the loop-back
test.
1 — Test is currently running.
2 — Test failed because loop back could not be activated.
3 — Test failed because test pattern could not be detected.
4 — Test has been deactivated.
v. Error 3901 is used to give status information about a Far CSU Loopback
test. The value in the Aux Data field indicates the status of the loop-back
test.
1 — Test is currently running.
2 — Test failed because loop back could not be activated.
3 — Test failed because test pattern could not be detected.
4 — Test has been deactivated.
w. Error 3902 is used to give status information about a One-Way Span test.
The value in the Aux Data field indicates the status of the span test.
1 — Test is currently running.
2 — Test has failed because test could not be activated.
3 — Test pattern was not received from the far end.
4 — Test has been deactivated.
x. Error type 3999 indicates that the circuit pack sent a large number of
control-channel messages to the switch within a short period of time. If
Error Type #1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity. If Error Type #1538 is absent, then the
circuit pack has not been taken out-of-service, but it has generated 50% of
the messages necessary to be considered hyperactive. This may be
completely normal during heavy traffic periods. However, if this error type
is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.

Descriptions and Error Codes
Always investigate tests in the order they are presented in
8-596. By clearing error codes associated with the NPE Connection Audit test, for
example, you may also clear errors generated from other tests in the testing
sequence
