The base stations in a channel group act as one. This is made possible by
distributed voting. A channel group can operate in simplex or duplex
modes, which means that each base station has either one voter that applies
the same voting rules to the same signals in simplex mode, or two voters in
duplex mode that allow two directions of speech flow simultaneously. For
example, in simplex mode, when the console operator presses PTT, all base
stations in the channel group transmit, not just the base station connected to
the dispatch console. If the base stations receive more than one signal, they
vote on the best one and then repeat it and/or pass it to the dispatch console.
If the base stations in a channel group have the repeat function enabled, that
channel group acts as a wide-area repeater (however, dispatcher calls and
control panel calls are given priority over radio calls).
If the repeat function is disabled, the channel group acts as a wide-area line-
connected base station. Calls received by any base station are sent to the
dispatcher and calls from the dispatcher are transmitted via all the base
stations.
