1. An external call connects to an external number (either by transferring with Tandem Trunking or
by DISA caller).
2. After 10 minutes (Tandem Trunking = Program 24-02-07 or DISA = Program 25-07-07), a warning
tone is heard and the user dials # (Program 20-28-01) to extend the conversation.
3. After three minutes (Program 20-28-03), the warning tone is heard again. After 30 seconds (Tan-
dem Trunking = Program 24-02-10 or DISA = Program 25-07-08), the call is disconnected.
Conditions
•
Tandem Trunking requires loop start trunks with disconnect supervision.
•
The maximum number of simultaneous trunk-to-trunk conferences allowed is determined by the Con-
ference feature setup. Refer to the Programming section for this feature.
•
The Continue/Disconnect code must be DTMF.
•
With an analog trunk, the Continue/Disconnect code may work using DTMF sounds from the oppo-
site side trunk. With an ISDN trunk, Program 14-01-25 must be enabled to detect the Continue/
Disconnect code.
•
The Continue/Disconnect code is not accepted while dialing a trunk.
•
Continue/Disconnect codes do not work if all receivers are busy.
•
A trunk can be set up to automatically tandem trunk/forward to an outside telephone number or
Speed Dial - System/Group Dialing bin.
•
Other programmed options for incoming and outgoing calls can affect how calls are handled. Refer to
Central Office Calls, Answering/Central Office Calls, Placing and check or program these options as
needed.
•
DISA calls also use the same Continue/Disconnect codes.
•
After initiating an unsupervised conference, selecting one of the line keys allows you to barge-in to
the conference.
•
If the station that barges into an unsupervised conference hangs up, the conference is terminated.
•
A Trunk-to-Trunk transfer can be established by the following operation:
1. While talking to an outside party, press Hold.
2. Access a second outside line and dial the desired number.
3. Press Transfer to complete the Trunk-to-Trunk transfer.
When the second call is to be transferred to another station (Not Trunk-to-Trunk), the user should press
Hold at step 3, then dial the desired station, and press Transfer to complete the transfer.
