Image Number 3 for United States Patent #6151482.
An operation and maintenance communications link is established between an antenna near parts component and transmitter and receiver of a transceiver site assembly. The transmitter and receiver are connected to a remote antenna by means of a radio frequency feeder supporting a plurality of communications channels. A radio transceiver is connected to the antenna near parts component. A communications connection comprising the operation and maintenance communications link is established between the radio frequency transceiver and the transmitter and receiver over the radio frequency feeder connected to the antenna using a selected one of the supported communications channels. Another implementation further utilizes an air interface connection supporting the selected communications channel to provide the operation and maintenance communications link.
