I-4 Individual Trunk Access
General Description
This feature permits an Attendant to access an individual trunk within a trunk group via dial access at the
ATTENDANT CONSOLE [A-3].
Operating Procedure
1. Press the TKSL key.
2. Dial the trunk route number (2 digits or 3 digits).
3. Dial the trunk identification number (3 digits).
4. If the trunk is idle, dial tone will be received.
OR
1. Press an idle TKSL key.
2. Dial the Central Office code number (4 digits).
3. If the trunk is idle, dial tone will be received.
Note:
On a system basis, either the Central Office code number or trunk route number and the trunk identification
number dialing can be assigned.
Service Conditions
1. A digital display will appear on the ATTENDANT CONSOLE [A-3], which will consist of either:
a.) TENANT [T-12] number, route number, and trunk number, or
b.) Central Office code number. This data is programmed on a per-route basis.
2. If the trunk is busy, the Attendant will receive a busy tone.
3. The Attendant can use ATTENDANT OVERRIDE [A-7], if it is included in system programming, to gain
entry into a particular trunk when it is in use.
4. If the trunk is made busy, either by hardware or software control, the Attendant can still access that trunk
using the above mentioned operating procedure.
5. The Desk Console is not available for this feature.
6. Central Office Code (COC) is not available to access an individual trunk through FCCS link.
Interactions
1. If the trunk is busy, ATTENDANT OVERRIDE [A-7] may be used. THREE-WAY CALLING [T-2] is
established following a Warning Tone. If the station should disconnect, the Attendant Console can either
disconnect or extend the trunk to another station via the keypad by pressing the START key and entering
the desired telephone number.
2. A station may access a specific trunk if it is allowed a Service Feature Class that allows SFI 39, Individual
Trunk Access. The station then goes off-hook and dials the INDIVIDUAL TRUNK ACCESS feature
access code. This requires assignments in ANPD and ASPA. In ASPA SRV = SSC (Service Code);
SID=17. Assign for a Connection Index of Normal (N). Individual Trunk Access also allows the station
to conduct Interoffice trunk tests. Refer to the NEAX2400 IPX System Operations and Maintenance
Manual, system message [6-I].
