| − | 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.

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.
