The AlphaCom can be interfaced to non-selective mobile radio systems via the IP-ARIO. The audio coming from the mobile radio gateway is distributed to the intercom stations in the AlphaCom by using the simplex conference feature. A user can listen to the radio conference by dialing the appropriate conference directory number 8201 - 8250. Any number of stations can listen in. The M-key of the station works as a PTT button. A user can press the M-key to talk back to the radio and to all other stations listening to that radio conference. When the M-key is pressed a RCO is operated in the AlphaCom. The RCO triggers a relay in the IP-ARIO board, which is used for keying of the radio transmitter. Restrictions can be set on which stations are allowed to do talkback, and which stations are allowed to listen only.

Connections
- 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.
- The IP-ARIO must be registered to the AlphaCom through the IP network.
AlphaPro programming
Default Speaker
The IP-ARIO must be set as a 'Default Speaker' in the conference. From the AlphaPro main menu select the button 'Simplex Conference', pick a free conference from the list box, and set the IP-ARIO as the 'Default Member'. Check the flag "Default Member is Default Speaker".
RCO Operation
One relay is used for keying the transmitter. The relays in the IP-ARIO are controlled by RCO's. IP-ARIO RCO's needs to be mapped.
The RCO's are configured in the Event Handler. In the Users & Stations window, highlight the IP-ARIO in the listbox, and select the button Events. Press Insert to create an event with the following parameters (here RCO 42 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.
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.
