From Zenitel Wiki

ICX-AlphaCom Intercom System

This article describes the various settings available through the web interface of Zenitel IP Stations when operating with an ICX-AlphaCom or AlphaCom XE server.

The station web interface

Station Web images and description in this article is based on the latest released software version.

Note icon The menus and parameters displayed may vary depending on the station type (e.g. Compact, Industrial or Ex).

Main tab


  • Log In to the station
  • The Information page will now be displayed, showing the IP station configuration and status.
The Information page

Main Settings

  • Click Main > Main Settings to access the page for configuring station mode and IP parameters.
The Main Settings page

Station Mode: Select the Use ICX-Alphacom radio-button.

Product Model And Accessory: Depending on the type of station hardware, there are different Product models and accessories to choose from. Find your model here: Station Models

Registration Settings:

  • ICX-AlphaCom IP-address: Enter the IP address of the ICX-AlphaCom server to which the IP station is to be registered
  • Number: Enter the directory number of the station. This must match the directory number defined in the ICX-AlphaCom server
- If a directory number is not entered, the station will register with its MAC address. The MAC address is found on the Station Information page and needs to be entered in the ICX-AlphaCom server using the AlphaPro PC tool

IP Settings:

  • DHCP – Select this option if the IP station shall receive IP Settings from a DHCP server.
  • Static IP – Select this option if the IP station shall use a static IP address. Enter values for:
- IP-address
- Subnet-mask
- Gateway
- DNS Server 1 (option for network administration, not used in ICX-AlphaCom mode)
- DNS Server 2 (option for network administration, not used in ICX-AlphaCom mode)
- Hostname (option for network administration)
  • Read IP Address: Check the Read IP Address box to enable an unregistered station to speak the IP address when the call button is pressed. "Read IP Address" is default enabled.
  • Disable Reset to Factory default settings using frontboard and I/O (not available on all models): Check this option to avoid unwanted or accidental initiation of the factory reset procedure from an input or button.
  • Enable RSTP (not available on all models): Check the Enable RSTP box to enable RSTP. RSTP is only required when using redundant networking
  • Ethernet Speed 10 Mbits/s (not available on all models): Default Ethernet speed is 100 Mbit/s unless switch is configured to 10 Mbit/s

Click Save followed by Apply to apply the new configuration settings.


  • Click Main > Recovery to access the page for recovery functions.
The Recovery page

  • Reboot system: Perform a full Linux reboot. No configuration is lost
  • Reboot main application: Perform a restart of the intercom application. No configuration is lost
  • Factory reset: Set all parameters to Factory Default values. The station will get static IP Address
  • Factory reset with DHCP: Set all parameters to Factory Default values. The station will get IP Address from DHCP server. If no DHCP server in the network, it will get a random 169.254.x.x IP address.
  • Clear local ZAP profile: For special purpose
  • Delete ZAP data.lua: For special purpose

DAVC Settings

The Distributed Automatic Volume Control (DAVC) is an algorithm which is using one or more microphones ("AVC Source") to measure the ambient audio/noise level, and adjusts the loudspeaker output level of the PA amplifier ("AVC Receiver") according to the ambient audio level.

See the article Distributed Automatic Volume Control (DAVC) for details about this feature.

Offline Relays

Fallback mechanism that makes it possible to designate one input/dak per relay which will activate the relay on press, and deactivate on release when the ICX-AlphaCom is offline

Offline Relays page

I/O Settings

These settings let you choose if an I/O should be used as an Input or as an Output. By default all I/O's are set as Inputs.

  • Select Advanced ICX-AlphaCom > I/O Settings from the menu
I/O Settings page

  • Select either Input or Output options from the drop-down box for I/O Pins 1 to 6.

See also the article Turbine Inputs and Outputs in ICX-AlphaCom.

Sound Detection

The Sound Detection, also known as Voice Activity Detection (VAD) samples the audio level from the microphone located in the IP Station. If the audio level meets defined criterias an action in ICX-AlphaCom can be triggered.

Advanced Network tab


A set of SNMP functions are available in the IP station. SNMP (Simple Network Management Protocol) is a protocol for centralizing the management of devices in IP networks.

See SNMP in IP Stations for futher information.


IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a LAN, either establishing a point-to-point connection or preventing it if authentication fails. For details on configuration, see IEEE 802.1X.


VLAN is not applicable for the Turbine series. Only for IP Desk Master -V2, IP Flush Master -V2 and the INCA family. See article VLAN Tagging (IEEE 802.1Q) for details.


All IP Stations have an embedded firewall. See Firewall for details.
