The RF board contains the receiver and exciter circuitry.
The digital board converts information between analog and digital and
controls the maintainer’s access via the control panel. It also performs the air
interface signal processing for both analog FM and digital P25 modes.
The network board acts as the link between the digital circuitry and the
TaitNet P25 Network, and gives the base station an identity as a network
element. It also provides the physical connections for the Ethernet, analog
and RS-232 serial interfaces.
