c. The local loop test failed. Each failure increments the counter by 1 when
the local loop test fails. The counter is decremented when the loop test
passes. When the counter reaches a threshold of 3, an on-board MINOR
alarm is raised. This is the code that is generated when the link between
the circuit pack and the voice terminal is successfully reset. No technician
action is necessary.
d. The NPE Cross talk test failed. The counter is incremented by 1 when the
NPE Cross talk test fails. The counter is decremented by 1 when the NPE
Cross talk test passes. When the counter reaches a threshold of 3, an
on-board MINOR alarm is raised and the board is taken out of service.
e. The station went off-hook while it was in the ready-for-service state. Use
the status station command to determine the state of the station. The
off-hook should have moved the station to ready-for-service. No technician
action is necessary.
f. No terminal is connected to the Digital Line board. No maintenance action
is required.
g. The circuit pack’s message buffer is full. This may be caused by having
many display phones with heavy traffic connected to the circuit pack. No
action is necessary.
h. Internal system error; no action is necessary. The error counters 1, 2, 3, 4,
5, 6, 10, 11, 12, 13, 14, 15, and 16 do not have any significance for this
MO.
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. By clearing error codes associated with the Voice and
Control Channel Local Loop Around Test, for example, you may also clear errors
generated from other tests in the testing sequence.
