[[File:Page5lines.jpg|thumb|right|600px|Page/Party Conference 5 Line - principle]]

This article describes how the ICX-AlphaCom system can be configured to operate as a Page/Party line Conference 5 line system. <br>
Up to 16 participants can be included in AlphaCom XE and up to 64 participants can be included in ICX-500 across all 5 Party Lines

From each Intercom, one can:
* Press and Hold the Page button to make a PA Announcement
* Press and Hold the PTT button on a Handset or Headset if connected
* Select a Party Line to toggle in and out of a Full Duplex Conference
* Select other Party Lines without having to toggle off first
* View if Paging is Ongoing from the LED indications (if available)
* View if a Party Line is in use from the LED indications (if available)
* View which Party Line is connected to the device from the LED indications (if available) 

The stations must be '''Zenitel IP Devices'''. SIP devices are not supported in this application.

==Operation ==
The application is based on using a Zenitel IP Master Station with at least 6 DAK keys (IPDM, IPDMH, IP-CRM-V-2) or a Substation with 6 buttons (TFIE-2 and TFIX-2).

DAK 1 - 5 are programmed to join and leave a Party Line.
DAK 6 is programmed as the Page button.
M-Key and PTT are also programmed as Paging buttons 

Page:

LED Behavior:
*Party Line is Red - In Use at this time.
*Party Line is Green - Current Party Line connected
*Page button is Red - Ongoing Page

== Number plan ==
The application is using the [[Duplex Conference]] feature of the ICX-AlphaCom. Duplex Conference 1 - 5 (8301 - 8305) are hardcoded for use as Party lines 1 - 5. 

=== General rules===
*UDP group 1: All Page/Party Stations
*Group 85 (2):  Paging Group. Configured with "Automatic M-key".
*Group 86 (3): All Page/Party Stations with DAK LED
*Group 11-15: Dynamic groups containing current conference members in conference 1-5
*UDDs: UDD equal to physical number is used as "Conf Flag" to store current conference membership
*DAK 1-5: Hardcoded for Duplex Conference 1-5 (8301-8305). Note that DAK tables must be empty
*DAK 6: Paging button
*M-key/PTT: Paging button
