Method D - Automatic Tandem Trunking Setup to Speed Dial Number

This method allows an extension user to easily set up an Unsupervised Conference with a call

they have placed on Hold. A Class of Service option is available, which allows or denies an

extension user from automatically setting up a Conference/Tandem Trunking call after hanging

up the telephone.

Trunk Continue/Disconnect Codes Added

Software enhances the forced trunk release option with the Tandem Trunking and DISA features. Users

can use a Continue or Disconnect service code. The Continue service code extends the conversation a

programmed time. If the user enters the Disconnect service code, the call is disconnected immediately.

The following example indicates how a call is handled with the system programmed as follows:

Program 14-01-25: 1 (Continued/Discontinued Trunk-to-Trunk Conversation)

Program 20-28-01:

Program 20-28-02: No Setting (No Conversation Disconnect Code is entered)

Program 20-28-03: 180 (Conversation Continue Time)

Program 24-02-07: 600 (Only used with Trunk-to-Trunk Transfer Release Warning Tone)

Program 24-02-10: 30 (Only used with Disconnect Trunk-to-Trunk)

Program 25-07-07: 600 (Long Conversation Warning Tone Timer)

Program 25-07-08: 30 (Long Conversation Disconnect)

1. An external call connects to an external number (either by transferring with Tandem Trunking or by DISA

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

3. After three minutes (Program 20-28-03), the warning tone is heard again. After 30 seconds (Tandem

Trunking = Program 24-02-10 or DISA = Program 25-07-08), the call is disconnected.

Tandem Trunking requires either loop start trunks with disconnect supervision or ground

start trunks.

The maximum number of simultaneous trunk-to-trunk conferences allowed is determined

by the Conference feature setup. Refer to the

for this feature.

The Continue/Disconnect code must be DTMF.

(Conversation Continue Code)

(Program 20-28-01) to extend the conversation.
