Unit installation

Notes:

The half/full duplex mode and semi-private mode settings are independent, but the semi-

private feature doesn’t work well in duplex mode because the autopatch hybrid is not (and

can not be) perfect. For this reason, only the combinations shown in the chart above are

useful in most situations.

This command allows you to control whether the audio from the autopatch gets muted

when one of the receivers that can send audio to the patch is active. When the controller

receives a command to bring up the patch, it connects that port and any ports that are

monitoring or connected to that port to the patch, so they can all take part in the call. Each

of those ports' transmitters will stay up for the length of the call. Each transmitter that is set

for full-duplex mode with this command will transmit the audio from the autopatch for the

entire length of the call; if it also transmits the audio from a receiver, it will mix it with the

autopatch audio. Each transmitter that is set up for half-duplex mode (the default) with this

command will mute the audio from the autopatch whenever someone keys up their radio to

talk to the person on the phone. This allows the control op to mute anything that the

person on the phone may say by simply keying up, rather than having to hang up the patch.
