Console Gateway
The console gateway interfaces a third party analog dispatch console to a Tait
P25 Network. It acts as an encryption/decryption point, enabling the analog
dispatch console to participate in encrypted calls. A console gateway is a
channel group member, connecting the dispatch console to the channel
group.
Trunked Analog Gateway
The trunked analog gateway interfaces a third party analog dispatch console
to a Tait P25 trunked network. Each trunked analog gateway makes a
‘channel’ available to the dispatcher by providing a connection into the
trunked network. The dispatch console can be considered a virtual radio,
with the gateway providing the dispatcher with a radio identity on the
trunked network. The trunked analog gateway acts as an encryption/
decryption point, enabling the analog dispatch console to participate in
encrypted calls.
