Issue 1 June 2005 987
w. Error Type 3901: gives status information about a Far CSU Loopback test. The value in the
Aux Data field indicates the status of the loop-back test.
Aux Data 1: Test is currently running.
Aux Data 2: Test failed because loop back could not be activated.
Aux Data 3: Test failed because test pattern could not be detected.
Aux Data 4: Test has been deactivated.
x. Error 3902: gives status information about a One-Way Span test. The value in the Aux
Data field indicates the status of the span test:
Aux Data 1: Test is currently running.
Aux Data 2: Test failed because loop back could not be activated.
Aux Data 3: Test pattern was not received from the far end.
Aux Data 4: Test has been deactivated.
y. Error Type 3999: 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.
