Trunking Communication Modes
There are two different trunking communications modes, “Trunking, Chan Grant on High
COR” and “Trunking, Chan Grant on Low COR”. (See
Figure 11) These two
communications modes are designed for operating with a trunked radio system that can
provide a channel grant signal to the Model 26. Like the COR communications modes,
the different trunking modes are based on the logic state of the channel’s active grant
signal. In these communication modes, when the Model 26 wants to transmit, it activates
its PTT line signaling a transmit request. When a channel is available the radio must
respond with a grant signal to the Model 26’s RX COR input. There are four other system
parameters associated with the Channel Grant signal: Trunking Grant Debounce,
Trunking Grant Timeout, Trunking Grant Retry Delay and Trunking Tx Delay.
