TIE-TRK (Analog Tie Trunk)
Issue 1 June 2005 2307
o. Error Type 2305: 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.
p. Error Type 2561, 2817: these errors apply only to TN497.
q. Error Type 2562: 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.
r. Error Type 2817: 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 2-way trunk from both the near and the far ends. Attempt to place
the call again. If the error persists, execute the Tie Trunk Seizure test (#73), and follow its
outlined procedures.
s. Error Type 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 screen should be changed.
Error Type 3841: indicates that test calls made by the Automatic Transmission
Measurement System (ATMS) returned measurements in the unacceptable range.
