[[File:Mobile Radio TKIE.png|thumb|700px|Interface to non-selective mobile radio system using TKIE kit]]

The ICX-AlphaCom can be interfaced to non-selective mobile radio systems via a Turbine Extended kit ([[TKIE-2]]), hereafter called the interface. 

== Operation ==
* The audio from the mobile radio gateway is distributed to the intercom stations in the ICX-AlphaCom by using the [[Simplex Conference|simplex conference]] feature.
* An intercom user can listen to the radio by dialing the appropriate conference directory number (default 8201 - 8299). 
* Any number of intercoms can listen in. 
* The M-key of the intercom works as a PTT button. A user can press the M-key to talk back to the radio and to all other intercoms listening to that radio conference. 
* When the M-key is pressed the relay of the TKIE-2 is operated, keying the radio transmitter. 
* Restrictions can be set on which intercoms are allowed to do talkback, and which intercoms are allowed to listen only.

==Connections==
===TKIE===

*The [[TKIE-1|TKIE]] provides signals for audio out, audio in and a contact closure for keying of the radio transmitter. These signals are connected to the accessory connector of a mobile radio gateway.

Mototrbo pinning:
* 11=TX Audio to radio
* 12=Audio GND
* 14=RX Audio from radio
* 17=PTT
* 18=GND
* 21=Squelch active from radio


{{Note|In the TKIE web settings '''Line In''' must be defined as the '''Audio Input Source''', and the '''Automatic Gain Control''' must be '''Disabled'''}}

===IP-ARIO===

*The [[IP-ARIO]] provides signals for audio out, audio in and a contact closure for keying of the radio transmitter. These signals are connected to the mobile radio system.

===FBSAR===

*The [[FBSAR|FBSAR board]] provides signals for audio out, audio in and a contact closure for keying of the radio transmitter. These signals are connected to the mobile radio system.
*Towards the AlphaCom XE the [[FBSAR|FBSAR board]] is connected to a free [[ASLT]] subscriber port with a-, b-, c- and d-wires. An RCO signal (separate e-wire) is required for the relay operation. For easy installation '''use relay K2''' for keying the transmitter (PTT). The [[FBSAR - Audio Interface Unit|FBSAR]] must be [[Powering Additional Equipment|powered by 24VDC from the exchange]].
*There are four jumpers on the FBSAR, S1 to S4, they should all be set in the "down" position (2-3).
*Two potentiometers on the FBSAR allows you to adjust the input and output signal levels

==AlphaPro programming==
The IP-ARIO and the TKIE must be configured to register to the ICX-AlphaCom through the IP network.

===IP-ARIO Audio License===
In AlphaPro, '''Users & Stations''' window, click the '''Station Type''' tab.
Under '''IP-ARIO''', enable the '''Request Audio License''' flag.

===Default Speaker===
The interface must be set as a 'Default Speaker' in the conference. From the AlphaPro main menu select [[Simplex Conferences (AlphaPro)|the button 'Simplex Conference']], pick a free conference from the list box, and set the interface as a 'Default Member'. Check the flag "Default Member is Default Speaker".

===RCO Operation===
One relay is used for keying the transmitter. The relay in the interface is controlled by the RCO command in the event handler. The relay outputs of the interface needs to be mapped to a logical RCO.

<br style="clear:both;" />

The RCO is configured in the [[Event Handler]]. In the '''Users & Stations''' window, highlight the interface in the listbox, and select the button '''Events'''. Press '''Insert''' to create an event with the following parameters (here RCO 1 is used as an example):

===Set restrictions on Talkback (optional)===
Each Simplex Conference has a 'Minimum Talk Priority' setting, with four levels available:

:*Low (default)
:*Medium
:*High
:*Alarm

Each station has a similar 'SX Conf. Talk Priority' setting ('''Users & Stations''' -> '''User Preferences''' tab) which must be higher than the setting of the conference, else the station can only listen to that conference.
[[Image:MobileRadioInterface 6.PNG|thumb|left|400px|Restriction on talkback is controlled by the 'SX Conf. Talk Priority' setting]]
<br style="clear:both;" />

All conferences are by default set to "'Minimum Talk Priority' = Low", and all stations are by default set to "Medium". I.e. all stations are allowed to do talkback.
