ENA Configuration - ICX-AlphaCom mode
From Zenitel Wiki
This article describes the configuration required for the Zenitel IP Amplifiers (ENA2100-AC2 & ENA2200-AC2) to operate with an ICX-AlphaCom server. The ENA Amplifiers are configured through their web interface. The ICX-AlphaCom server is configured using the PC tool AlphaPro.

Software and License requirements
Minimum Software requirement
- ENA Amplifier: 4.9.3.0
AlphaCom XE series
- AlphaCom: 12.5.3.0
- AlphaPro: 11.7.3.2
ICX-AlphaCom
- ICX-AlphaCom: 1.1.3.0
- AlphaPro: 12.1.3.0
License requirement
- One ENA Amplifier Channel License is required per amplifier channel or audio in channel.
- For example, if Channel 1, Channel 2 and Audio In all have their own directory numbers, then 3 ENA Amplifier Channel License are required
- To enable the use of Background Music at 48 kHz PCM, a High bandwidth audio license is required. It is sufficient with one HD Audio license per ICX-AlphaCom server.
To install the license, log on to the web interface of the ICX-AlphaCom server, and select System Configuration > Licensing.
Directory Numbers
The ENA Amplifier supports 3 registrations on 3 separate directory numbers:
- First registration: CH1 audio output, RCO, RCI control and fault status monitoring
- Second registration: CH2 audio output
- Third registration: Mic In or Line in audio input

Station Main tab
Station Information
- Log In to the amplifier
- The Station Information page will now be displayed, showing the amplifier configuration and status.
|
To find the IP address of the amplifier, use the Menu Selection Knob on the front of the amplifier, and navigate to Information > Network. |
Main Settings
- Click Station Main > Main Settings to access the page for configuring Station Mode and IP parameters.
Station Mode: Select the Use ICX-Alphacom radio-button.
Registration Settings:
- ICX-AlphaCom IP-address: Enter the IP address of the ICX-AlphaCom server to which the amplifier is to be registered
The amplifier can be assigned up to three separate directory numbers: Loudspeaker Channel 1, Loudspeaker Channel 2 and Audio Input. The directory number(s) must also be defined in the ICX-AlphaCom server.
- CH1 Out Directory Number: The first registered channel. This channel only supports audio output to CH1 amplifier.
- CH2 Out Directory Number: The second registered channel. This channel will output audio to CH2 amplifier.
- Disabled option will disable this channel registration
- Mirror CH1 audio will play CH1 audio stream on CH2, and CH2 will not require directory number and will not use any license
- When channel is mirrored, channel monitoring and volume controls (in web and GUI) are still separate
- Audio In Directory Number: The third registered channel. This channel is used to send mic or line in audio to the ICX-AlphaCom
- Disabled option will disable this channel registration
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)
- - DNS Server 2 (option for network administration)

Advanced ICX-AlphaCom tab
DAVC Settings
The Distributed Automatic Volume Control (DAVC) is an algorithm which is using one or more microphones to measure the ambient audio/noise level, and adjust the loudspeaker output level of the PA amplifier according to the ambient audio level. See Distributed Automatic Volume Control (DAVC) for more details.
Time Settings
- Select Advanced ICX-AlphaCom > Time Settings from the menu
Time Settings: You can enable Network Time Protocol, select the time zone and set the hostname or the IP address of the NTP server.

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

- Voltage is saved independently
Channel 1/Channel 2 options:
- Tick Tone: Choose the wanted ticktone file to be played. Very useful tool for commissioning and troubleshooting.
- Master Volume in dB changes channel volume for digital audio. Range -40dB to +2dB. (-10dB is default).

- To get access to monitoring configuration options, either type of monitoring has to be enabled
- Line Monitoring: Enable or Disable Speaker Line monitoring
- LET Monitoring: Enable or Disable Line End Transponder monitoring
- Route Line In to ch'x': The amplifier is able to play audio directly from it's Line Input without it being registered to an ICX-AlphaCom server. Using these options one can route audio from the Line IN input directly to the loudspeaker output.
- Always Off: Routing is always disabled
- No IP Audio/Reg Route audio if no sound is being played from IP network, or there is no server connection or the amplifier is not registered to a server.
- Not Registered: Route audio if there is no server connection or the amplifier is not registered to a server.
- Always On: Routing is always enabled
- See more details at ENA amplifier in Bypass Mode

Line In options:
- Gain changes line in gain (0 - 47 dB)
- Pilot Tone Sensing Enables or disables the Line In Pilot Tone Sensing.
Testing
There are two tests that can be run:
- LEDs: Makes the four status LEDs (Power, Amp, Fault and GND) flash for 5 seconds
- Fault Relay: Turns on the Fault Relay for 5 seconds
IO Monioring
There are 3 Control Outputs (RCO/GPO) and 2 Control Inputs (RCI/GPI) available.
Configuration of the outputs and inputs is done from AlphaPro:
- The Control Output must be mapped to a Logical RCO. The operation of the logical RCOs is configured in the Event Handler window.
- The Control Input is configured in the RCI table in AlphaPro
The ENA amplifier offers monitoring of the outputs and the inputs:
- RCO/GPO monitoring alerts when the signal on the contacts are outside the configured legal values.
- Limit Low OK - If the RCO triggers and the voltage is below this value, it is reported as "Shorted".
- Limit High Not OK - If the RCO is not above this voltage when output is high, it is reported as an "Overload".
The RCOs/GPOs can be tested from this page. They can be set and cleared. Remember to set them back to System before ending the test.
- RCI/GPI config allows configuring the thresholds for when the RCI triggers. An RCI has an open voltage of 10V across the terminals. A resistor network is needed to ensure that RCI's can be monitored properly.
- Monitor RCI enables monitoring of RCI.
- Not Connected - When the voltage on the pin is higher than this threshold, it's set as Not Connected.
- Not Pressed - Low threshold for the RCI to be considered not pressed.
- Pressed - High threshold for the RCI to be considered pressed.
