When a master station calls a substation it is often required that the conversation should have a fixed speech direction from the substation towards the master station.<br\>
 
By using the AlphaCom Event Handler, it is possible to force the M-key on the B-subscriber ON when the conversation starts, and release the M-key when the conversation cancels. This will force the initial speech direction to be from the substation towards the master station. By operating the M-key, the master can override the speech direction. (In AlphaCom, the last one who is pressing the M-key will get the speech direction). If the master makes a short M-key press the conversation will turn to voice switched duplex.

If there are several stations to have initial speech direction set, you must create the same two events for each of the stations and set the new station as Event Owner.
 
 
 
== Option – Use of UDP Groups ==
 
When several stations are going to have the same event action programming, they can share the same event programming by using [[UDP]] groups. The stations must be included in a UDP (User Defined Property) group, and the UDP group is set as Owner of the event. In this way the total number of events are reduced.

In general there are 8 UDP groups in AlphaCom. By default all stations are included in UDP group 8. To include a station in an UDP group, press the ''Users & Stations'' button from the AlphaPro main menu. Select the station from the list box, and press the ''UDP'' button. Include the station by ticking one or more of the check boxes. You can assign an appropriate text to the UDP group by pressing the ''UDP Text'' button.

Normally you can return to duplex mode by pressing the M-key quickly. In AMC there is a timer defining how short this M-key pulse have to be. If the timer is set to 0, it will not be possible to revert back from simplex to duplex. In this way all conversations will be in simplex mode. The timer is not available from AlphaPro, it has to be changed by using the nvram editor of the [[TST console]].

If the Simplex mode should not apply to the whole exchange, but to a single station or a limited group of stations only, simply change the owner of the event to that single station, or include the relevant stations in an [[UDP|UDP group]] and set this UDP group as event owner.

General

This article describes how you can override the voice-operated duplex (VOX), and set the system in Simplex (Press To Talk) mode.

Software requirement: AMC 10.52 or newer.

Whole Exchange in Simplex Mode

This event will set the whole exchange in simplex (Press To Talk) mode. Simplex mode will also work across AlphaNet.

In AlphaPro, go to Exchange and System -> Events, press Insert and create the following event:

Event that sets the whole exchange in simplex mode


Action commands:

@U%2.nod $SIMP L%2.dir U0 U1


Initial speech direction will be from B-subscriber towards A-subscriber.

If the Simplex mode should not apply to the whole exchange, but to a single station or a limited group of stations only, simply change the owner of the event to that single station, or include the relevant stations in an UDP group and set this UDP group as event owner.
