Corrective Action
Analog trunk issues.
Examine that the analog
trunk is OK by using
individual trunk access and
testing on the frame.
Note
:
On the EX platform,
individual trunk access
is not supported
as ISDN, T1, and
FXO trunks are
not assigned trunk
numbers when
programmed.
System not receiving trunk
calls.
Answer point not
programed.
Verify SMDR records to
see which trunks have
received incoming calls.
Verify that the answer point
is programmed correctly
and is functional.
Outgoing calls are dropping
after a couple of minutes
into the conversation.
The system is not receiving
answer supervision from
the central office and is
timing out.
If the Central office
cannot provide answer
supervision on answered
calls, go to the CO
Trunk Circuit Descriptors
form and change the
value in the field “fake
answer supervision after
outpulsing” to yes.
