PACOM Unison - ICX-AlphaCom integration

From Zenitel Wiki



PACOM Unison is a security management application designed for security operators and administrators to set up access control and alarm system monitoring and control at a site. This comprises

  • Access Control
  • Alarm System Monitoring
  • Events recording (Database)
  • Configurable Nodes

A detailed description of the PACOM Unison system can be found in the help menu (press the HelpButton.jpg-button in the upper right corner of the GUI). For the configuration of an intercom system based on the ICX-AlphaCom or Alphacom the section “Intercom – Stentofon Alphacom” gives a description how this is setup (In the following sections only the name ICX will be used when there is no confusion between ICX-AlphaCom and AlphaCom).

PACOM Unison / ICX Demo System

This article is a detailed description on how to setup the demo shown below

Demo System Setup


PACOM Unison

The Unison system must be licensed for intercom support and an appropriate number of intercom units. Please contact PACOM for details.


ICX-AlphaCom requires the presence of the appropriate API/OPC license.

  • 1002602306 - ILI-API64 - API License Supporting 64 Stations
  • 1002602309 - ILI-API512 - API License Supporting 512 Stations

With ICX-AlphaCom it is possible to purchase a single Product Key which covers all stations connected to all ICX-AlphaCom server in a network. ICX-AlphaCom licenses can be stacked, i.e. 1x 1002602306 + 2x 1002602309 gives 1088 API licenses which can be used on 2 or more ICXs. Compatibility between ICX-AlphaCom and PACOM Unison is as from ICX-AlphaCom software version


The AlphaCom requires the presence of the appropriate API/OPC license. Note that every AlphaCom in an AlphaNet requires such a license.

  • 1009649901 - STENTOFON API License Supporting 40 Stations
  • 1009649902 - STENTOFON API License Supporting 80 Stations
  • 1009649903 - STENTOFON API License Supporting 160 Stations
  • 1009649904 - STENTOFON API License Supporting 240 Stations
  • 1009649905 - STENTOFON API License Supporting 320 Stations
  • 1009649906 - STENTOFON API License Supporting 400 Stations
  • 1009649907 - STENTOFON API License Supporting 552 Stations


Although the integration requires API/OPC licenses in ICX-AlphaCom or AlphaCom, communication is via one of the ACDP-ports. The documentation for PACOM Unison suggests to use ACDP port 4, but as there is no difference in operation of the ACDP-ports another port can be selected if ACDP port 4 is already in use.

As from ICX-AlphaCom software version, it is not necessary to also purchase license 1002602400, ILI-IF. The API/OPC license will also open all other protocol ports on ICX-AlphaCom.

ICX Setup

The configuration tool AlphaPro is used for setting up the following parameters

IP Connection

The ICX uses the ADCP link for establishing the connection to the PACOM. Select “Exchange & System”->”Serial Ports” and make the settings as shown below

ACDP Link 4

Check the setup by selecting “Exchange & System”->”Devices”

Unison Device

Configure the “broadcast event messages to remote node" property to the node number of the connected ICX. Select “Exchange & System”->”System”->”Logs and Errors”

Broadcast Events

Configure the “Faulty Station Line" event of each exchange. Select “Exchange & System”->”Events”

Faulty Line Event

Enable extended wire check.

PACOM Unison Setup

The Unison system supports importing existing Stentofon Alphacom configurations as well as some limited manual configuration. When importing, nodes in the Stentofon system are replicated in the Unison system - this makes device configuration faster and less prone to error. To import a configuration:

  • Create a "Stentofon Alphacom" device in the Unison system. This is the "root" node for the Alphacom system and provides a connection to the Alphacom server.
  • Use the "generate" command on the "Stentofon Alphacom" device.
Generate System

It is also possible manually to configure the ICX system. Select "System Configuration"->"Hardware"

Hardware Configuration

Select "Create Device"->"Stentofon Alphacom"

Create Stentofon Alphacom

Select "Create"->"Exchange".

Add Exchange/Alias Station

Also, add an "Alias Station" for the for the operator intercom device.

Add all intercom devices. Select "Create"->"Station"

Add Station

Set the events and actions for all stations. All alarms are set as an "Alert Annunciation Alarm"
The operator intercom device only generates events "Line Busy" and "Line Fault".
