8.4. Conversation Method
There are three different conversation methods possible when the master station is used. The conversation
method is determined by the other party's station type and handset use.
(1) Voice-operated switching conversation ("VOX" in
the table below)
When both parties are talking coincidentally, the
master station's (telephone's) party voice is
transmitted to the substation. If the master station's
party stops talking, the substation's party voice can be
heard at the master station.
(2) "Press-to-talk" control conversation ("PTT" in the
table below)
The [PTT] key is pressed to talk, and released to
listen.
(3) Duplex conversation
Similar to the method of a standard telephone.
The following table shows the conversation modes for all of the various station combinations.
