n. Reorder message. The trunk could not be seized. This error causes the
Tie Trunk Seizure Test (#73) to run and is considered a problem only if that
test fails, logging error 1793. In this case, the trunk may be placed in the
ready-for-service state, allowing only incoming calls. This service state
shows up as
disconnected
on the trunk status screen. Run the Tie Trunk
Seizure Test and follow recommended procedures.
TN439 logs aux data 57424 or 50944. Other circuit packs log 50944. This
error is associated with Test #747 for TN439, Test #73 for TN497, and no
test for the others.
o. These errors apply only to TN497.
p. Retry Failure error. This error is logged only. It is not a hardware failure and
hence does not start any testing or generate any alarms. This error comes
from call processing and is generated when a second attempt (retry) to
seize an outgoing trunk fails.
q. Glare error. This error is logged only. It is not a hardware failure and hence
does not start any testing or generate any alarms. This error is the result of
a simultaneous seizure of a two-way trunk from both the near-end and the
far-end. Attempt to place the call again. If the error persists, execute the
Tie Trunk Seizure Test (#73) and follow its outlined procedures.
r. Error 3841 indicates that test calls made by the Automatic Transmission
Measurement System (ATMS) returned measurements in the
unacceptable range. Error 3840 indicates measurements were in the
marginal range. Use
list testcall detail
to examine the specific
transmission parameters which are out of spec, and investigate the trunk
for that kind of noise. If the noise is acceptable, then the AMTS thresholds
administered on page 4 of the trunk group form should be changed.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in Table 9-659 when inspecting
errors in the system. By clearing error codes associated with the
NPE Crosstalk
Te s t
for example, you may also clear errors generated from other tests in the
testing sequence.
