Direct Inward Line (Dil) - NEC Xen Topaz Features And Specifications Manual

Direct Inward Line (DIL)

• Description
A Direct Inward Line (DIL) is a trunk that rings an extension, virtual extension or
Department Group directly. Since DILs only ring one extension or group (i.e., the DIL
destination), employees always know which calls are for them. For example, a
company operator can have a Direct Inward Line for International Sales Information.
When outside callers dial the DIL's phone number, the call rings the operator on the
International Sales line key. The DIL does not ring other extensions.
DIL Delayed Ringing
Extensions in a Ring Group can have delayed ringing for another extension's DIL. If the
DIL is not answered at its original destination, it rings the DIL No Answer Ring Group.
This could help a Technical Service department, for example, that covers calls for an
Inside Sales department. If the Inside Sales calls are not answered, they ring into the
Technical Service department.

Features and Specifications Manual
A. If unanswered, a DIL without delayed ringing rings an extension until the outside
party hangs up.
B. If a DIL rings a Department Group and all agents are busy, the system routes the
call as follows:
1. The trunk rings the overflow destination assigned in 22-08.
2. If there is 22-08 assignment or PC Attendant, the call rings according to
the Ring Group assignments in 22-04 and 22-05.
3. If none of the destinations in steps 1-3 above are available, the call contin-
ues to ring until a destination becomes free.
D. The DIL follows call forwarding programming, even to voice mail.
