The Base Radio (BR) provides reliable digital communications capabilities. Each Base
Radio contains the following subcomponents:
•
•
In the MTS 2 and 4, the Base Radio (BR) operates in conjunction with the Site Controller (SC) through a
properly terminated 100Base-T Ethernet link.

On the front panel, there is a DC power input, three parallel receiver (RX) inputs, a high power
transmitter output signal from the power amplifier, a service port, two interfaces to the Site Controllers,
and LED indicators. For more information on the LED indicators, see
