Procedure,
continued
5
If a conversation is in progress, press <START> to
exit. If a conversation is not in progress, press
<CNCL> to unlock the connection and free the trunk.
If the trunk is not busy, you hear dial tone, and see this
display:
6
Dial an outside number to check the trunk. Because
you’re already connected to a trunk, you don’t need a
trunk access code (usually 9) before the outside
number.
7
If the trunk is operational, you hear ringing or busy
tone after the outside number is dialed. If the trunk is
not operational, call your telephone system
maintenance company.
8
Press <START> to disconnect.
Note: The <LTA/VER> key is also used for the long
trunk alarm. The long trunk alarm causes the
<LTA/VER> key to flash when a trunk is
connected for an unusually long time. (See
“Receiving a Long Trunk Alarm” on page 2-55.)
When the <LTA/VER> key is flashing, you can
still use it to check a trunk that is not causing the
alarm.
