Difficulty Making Outside Calls - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Difficulty Making Outside Calls

NOTE:
The following procedure may help AT&T Helpline technicians analyze your
problem. However, you should not perform this procedure unless you have
experience removing the control unit cover and working with control unit
extension jacks. Before proceeding, consult system planning Form 2a, System
Numbering: Extension Jacks.
!
WARNING:
If you must check something on the control unit, proceed with caution.
Avoid standing on a box or chair to reach the unit if it is installed out of
easy reach. If you do not have a stable ladder or other proper equipment,
do not proceed; wait for the AT&T technician.
Possible Cause 5: A module or modules may be defective.
What to do: Identify the control unit module or modules where the telephones
are connected.
If the telephones are all connected to one module, there may be a
problem with the module. Call the AT&T Helpline at 1 800 628-2888.
If the dead telephones are connected to modules that also connect
working telephones, test the jacks on the modules. Identify the port
where each non-functional telephone is connected. Identify a second
port in the same module connected to a working telephone and unplug
the jack from the module. Plug the jack for the dead telephone into the
extension jack that is now open. If the telephone works, call the AT&T
Helpline at 1 800 628-2888.
If the telephones do not work when plugged into module jacks that are
known to be functioning, call the AT&T Helpline at 1 800 628-2888.

restrictions, if any (see Chapter 3 in System Programming ). If the extension is
toll- or outward-restricted, change it to unrestricted, if appropriate. Try again to
