T-23 Trunk Line Appearance
T-23 Trunk Line Appearance
General Description
This feature allows a D
term
user to directly access a Central Office trunk or TIE Line without dialing an access code.
Incoming calls can also be answered at the TRUNK LINE APPEARANCE [T-23].
Operating Procedure
To access an outgoing trunk
1. Press the TRUNK LINE APPEARANCE line/feature key.
2. Lift the handset or press the SPEAKER key. Central Office or distant PBX dial tone will be heard.
3. Dial the destination number.
To answer an incoming call from the TRUNK LINE APPEARANCE
1. Ringing and an LED indication alert the D
term
user of the incoming call.
2. Press the TRUNK LINE APPEARANCE line/feature key.
3. Lift the handset or press the SPEAKER key.
4. Answer the incoming call.
Service Conditions
1. A TRUNK LINE APPEARANCE can be accommodated on D
term
s, and 24/40-button Add-On Modules.
2. A TRUNK LINE APPEARANCE can be assigned as a SOFTWARE LINE APPEARANCE [S-33].
3. A TRUNK LINE APPEARANCE can be assigned in a Circular or Pilot Hunt Group.
4. A TRUNK LINE APPEARANCE is available for destination offices that can receive DP/PB signals.
5. CALL FORWARDING-ALL CALLS [C-5], CALL FORWARDING-BUSY LINE [C-2] and CALL
FORWARDING-DON’T ANSWER [C-3] can be set at the Attendant Console for a TRUNK LINE
APPEARANCE assigned to a Virtual Line Appearance or an unused data port.
6. A TRUNK LINE APPEARANCE can receive incoming calls from internal stations, DID, DIT, or TIE
Line trunks.
7. When a call is originated with the RECALL key and the trunk is busy, the call is in the queue waiting to
seize the idle trunk. If no dial tone has been found for two seconds, the calling party hears a busy tone (if
the idle trunk is found within two seconds, the station is connected to the idle trunk).
8. When TRUNK LINE APPEARANCE is used for the DP line, program two seconds or less for outgoing
inhibit timing after trunk release (ARTD CND 34: GUARD = 1-3).
Interactions
1. For incoming calls, the trunk must be assigned as a DIRECT-IN TERMINATION [D-7] trunk.
2. The trunk may still be seized by other stations or the ATTENDANT CONSOLE if the route is not isolated
from other features such as LEAST-COST ROUTING-3/6 DIGIT [L-6] or ROUTE ADVANCE [R-6].
3. The trunk may be selected by INDIVIDUAL TRUNK ACCESS [I-4]. If accessed, the D
term
will not have
a lit LED for busy condition, as would occur when a trunk is seized in a 1A2 key system. If the user of
TRUNK LINE APPEARANCE goes off hook to seize the trunk, busy tone is returned. The LCD displays:
