Station Web Interface - ICX-AlphaCom mode

ICX-AlphaCom Intercom System

This article describes the various settings availbale through the web interface for Zenitel IP Stations to operate 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.

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

Main tab

Information

• 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.

Recovery

• 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 169.254.1.100.
• 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.

Read more about Sound Detection.

RTSP Settings

RTSP Settings page

• Enable RTSP - enables RTSP traffic by allowing/blocking traffic from/to RTSP port
• RTSP Port - defines RTSP port - by default RTSP port is set to 554
• Enable RTSP Authentication - enables mandatory usage of RTSP credentials on stream setup
• RTSP URL - RTSP URL that can be copied into RTSP player. All supported RTSP streams are listed here: audio-only, video-only and audio+video stream URL for video Turbine devices and audio-only stream URL for other Turbine devices.
• Audio Source - defines when acoustic echo canceler is applied to mic+speaker voice. With this setting it is possible to choose whether only microphone signal is sent to RTSP stream or both microphone and speaker signals are sent to RTSP stream. On video Turbine stations this option can be defined separately for each stream.

Advanced Video Settings

TCIV+ and TCIV Video Stations also have settings for ONVIF. For details, see Advanced video settings for TCIV+ or RTSP and ONVIF Settings for TCIV Stations.

OLED Labels

See article OLED Labels on how to configure the display in the station models TCIS-4 and TCIS-5.

Address Book

See the article Address Book on how to configure the address book of the station models TCIS-6 and TCIV-6/TCIV-6+.

Keyboard Settings

Applies to the station models TFIE-x (Industrial station) and TFIX-x (Explosion proof station). See article TFIE Keyboard Settings for more details.

Time Settings

• Select Advanced ICX-AlphaCom > Time Settings from the menu

Time Settings page

Time Settings: You can enable Network Time Protocol, select the time zone and set the hostname or the IP address of the NTP server.

Audio Messages

A Turbine station can play a custom media (WAV) file when connection to the ICX-AlphaCom server is lost. The station can also play a custom media file when pressing the call button (or activating an input) and the call setup fails because the station is offline. See Audio Messages - Turbine for more detasils.

Advanced Network tab

SNMP

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.

802.1X

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

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.

Firewall

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