Refer to “DATA-CHL” before issuing the test network-
control [a | b] long command to determine if CDR, System
Printer, Journal Printer, and/or PMS Links are using the
DATA-CHLs and how to busyout these links prior to running
destructive tests on the DATA-CHLs.
Refer to “SW-CTL” before issuing the test network-control
[a | b] long command to determine the consequences of
running the Switch Control Reset Test (Test #93).
4. Issue the test data-module <ext> long command using the
extension for the DATA-CHL chosen in Step 3.
If the error happens again within 15 minutes, then replace the
circuit pack.
h. This error is not service-affecting and no action is required.
i. In a High Critical Reliability system, the vintage number of the TN777B
Network Control circuit pack must be greater than or equal to 17. The aux
value for error 3841 indicates the vintage of the current TN777B installed.
j. 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.

Descriptions and Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the
NPE Audit Test
, for example, you may also clear
errors generated from other tests in the testing sequence.
