ad. Error Type 3901 — is used to give status information on a Far CSU
Loopback Test. The value in the Aux Data field indicates the status of the
loopback test.
ae. Error Type 3902 — is used to give status information on a One-Way Span
Test. The value in the Aux Data field indicates the status of the span test.
af. 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 not present, 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.
