Direct Inward Line (Dil) - NEC SL2100 Features And Specifications Manual

ISSUE 1.0
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 telephone number, the call rings the
operator on the International Sales line key. The DIL does not ring other extensions.
There are 128 available trunks, 50 Department Groups, 128 extensions and 50 virtual extensions.
DIL Delayed Ringing
Extensions in a Ring Group can have delayed ringing for another extension 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.
Conditions
• If unanswered, a DIL without delayed ringing rings an extension until the outside party hangs up.
• 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 PRG 22-08.
2. If there is no PRG 22-08 assignment, the call rings according to the Ring Group assignments in
PRG 22-04 and PRG 22-05.
3. If none of the destinations in steps 1~2 above are available, the call continues to ring until a
destination becomes free.
• The DIL follows call forwarding programming, even to voice mail.
• When a call is transferred by Call Forwarding - No Answer, Call Forwarding - Busy, or DND, the
Reason for Transfer can display at the transferred extension.
• You can place DILs in trunk groups to make outgoing DIL calls easier.
• If a DIL destination extension is in DND, an incoming call rings according to Ring Group
programming (PRG 22-08 then PRG 22-05).
- If a user puts the telephone in Do Not Disturb, calls routed to the telephone in DND do not follow
call forwarding.
• A user can activate Group Call Pickup to intercept a DIL ringing another extension.
• Program a name for a DIL in PRG 14-01-01. This makes it easier to identify the incoming call.
• If a Multiline Terminal is busy, a second incoming DIL call provides Call Alert Notification, depending
on chassis programming. The second DIL call waits in line for the user to answer the call. The
outside caller hears ringback tone while this occurs.
• If an extension has a line key for a DIL, the call rings the key. If not, the call rings an available line
appearance. For other extensions, the DIL indicates busy.
• A DIL rings its assigned extension without Ring Group programming. A DIL only rings its assigned
extension. It does not ring other extensions in a Ring Group.
