TIE-DS1 (DS1 Tie Trunk)
Issue 1 May 2002

555-233-143
l. 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 DS1 Tie Trunk Seizure test (#136) and follow its
outlined procedures.
m. Error Type 3840 — Port Audit and Update test (#36) failed due to an
internal system error. Enter status trunk command, and verify the status
of the trunk. If the trunk is out-of-service, then enter release trunk
command to put it back to in-service. Retry the test command.
System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. For example, by clearing error codes associated with the
NPE Crosstalk test (#6), you may also clear errors generated from other tests in
the testing sequence.
For TN767B vintage 8 or 9 circuit packs, a failure of Test #136 causes a
subsequent failure of Test #7. Test #136 is part of the short sequence and
generates off-board alarms Test #7 is part of the long sequence and generates
on-board alarms. Before entering busyout, release, reset or test board long
commands, check the vintage number of the circuit pack with list configuration
board UUCSS. If it is TN767B vintage 8 or 9, do not use the above commands
until first making sure that Test #136 passes via test board short. Otherwise,
extraneous on-board alarms may be generated.
NPE Crosstalk Test (#6)
The NPE Crosstalk test verifies that this port’s NPE channel talks on the selected
time slot and never crosses over to time slots reserved for other connections. If
the NPE is not working correctly, 1-way and noisy connections may be observed.
This test is usually only part of a port’s long test sequence and takes on the order
of 20 to 30 seconds to complete.
