10-140 Issue 4 May 2002
o. 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.
p. Error Type 2
Check the Class of Restriction (COR) administered for the
Data Line extension assigned to the TN750 for uploading and downloading
announcements. The extension can be found by using list data-module.
System Technician-Demanded Tests: Descriptions
and Error Codes
Investigate tests in the order presented in Table 10-45 on page 10-140 when
inspecting errors in the system. By clearing error codes associated with the
Control Channel Loop Around Test, for example, you may also clear errors
generated from other tests in the testing sequence.
Note:
a. For a complete description of these tests, refer to the “XXX-BD (Common
Port Circuit Pack)” Maintenance documentation.
