in operation. In a single system, an extension within the same system can transfer a call to a
Department Group and the call will ring an extension within the Department Group once the
transferring user hangs up. In a networked system, the transfer will not go through and the call will
recall the extension performing the transfer.
STG Withdraw Mode
Call Recall Restriction for STG
Maximum Queuing Number
Enhanced Hunting Mode
Operation
1. When dialling the Department access code for the networked system, the call is dialled in the same way
as normal.
Department Step Call
After calling a busy Department Calling Group member in a networked system, an extension user can have
Department Step Calling Quickly call another member in the group.
Operation
To make a Step Call:
You step through Extensions within a Group.
1. Place call to busy Department Group member.
OR
Place call to Department Group pilot number.
2. Press Step Call key (SC 851: 36).
3. Repeat step 2 to call other Department Group members.
Direct Inward Dialling (DDI)
An incoming DDI call can be routed to an extension in a networked system.
Operation
For incoming DDI calls, the system uses DDI programming to determine how to route the call. If the
extension number is determined to be in the networked system, the call will be routed to the appropriate
system node.
It is possible to route to a Department Group Pilot number at a remote system.
It is not possible to route a DDI call to an IRG at the remote system.
The timer values are determined at the system for the incoming trunk.
Direct Inward Line (DIL)
A Direct Inward Line (DIL) is a trunk that rings an extension, virtual extension or Department Group directly.
The DIL trunk can call an extension at a networked system, if the DIL trunk is set to route to an extension
number at the other system.
Operation
1. An outside caller places a call to a DIL trunk.
2. The call will be routed to the networked system if the DIL target is defined as an extension at another
system.
Direct Inward System Access (DISA)
Networking allows DISA callers to place a call to an extension in a networked system. Some system
features can also be accessed from the networked system. The Class of Service is determined by the
password entered by the DISA caller. The password table is referred to by the system on the incoming
