Trunk Interface - Loop Start
The VB-44510UK Loop Start interface unit supplies 8 loop start analog exchange line circuits. In
addition, the VB-44510UK Loop Start interface unit may alternatively be used to connect to loop start
exchange lines.

Trunk Ringing Types
Description
Several types of trunk ringing are available for the System including the following:
•
Direct Dial Inward (DDI) Ringing
•
Direct Line (DL) Ringing
•
Direct Inward System Access (DISA) Ringing
•
Multiple Ringing
These ringing types may be used in any combination in the System.
DDI Ringing
DDI Ringing allows calls on a common trunk to be directed to ring to a specific extension or group of
extensions, etc. based upon the final digits dialled. These final digits are received from the DDI trunk
and compared to a DDI Table that determines where the calls should ring. Depending on the
assignments in the DDI Table, names or trunk numbers are displayed. (Names can be up to 10 digits
long.)

and compared to a DDI Table that determines where the calls should ring. Depending on the
assignments in the DDI Table, names or trunk numbers are displayed. (Names can be up to 10 digits
long.)
DDI Ringing can be very useful by sending calls directly to a specific extension, hunt group, etc.
based upon the number dialled. Since a relatively small number of trunks handle the DDI calls, this
can be more cost efficient than DL trunks or attendant group answering and transfer. (DDI may send a
call to a group using the Virtual Extension feature.) DDI Busy/Delayed Ringing is also available with
DDI Ringing. (See “DDI (DID) Day/Night Busy/Delayed Ringing” on page 58.)
