o. Error Type 3848This error indicates that the Tone/Clock circuit pack had
a loss of clock. If error 2305 is also logged, see note (j).
p. Error Type 3872
These errors indicate this Tone/Clock circuit pack had
a loss of Data Clocks. This error will impact mainly users on station
connected to Digital circuit packs. These users could be with out service.
If error 2049 is also logged see note (i).
q. 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.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. By clearing error codes associated with the
SAKI
Sanity Test
, for example, you may also clear errors generated from other tests in
the testing sequence.
Use the
list configuration control
command to find the Tone-Clock Circuit Pack
Code of the system. Look for the Short and Long Test Sequences according to
the Tone-Clock Circuit Pack Code.
