The method and apparatus for interfacing between a cell site controller, a cell system controller, and the radio transceivers of a cellular radiotelephone system is disclosed. To convey control information to the radio transceivers, the cell site controller enables one of a redundant pair of control data buses to a selected transceiver by placing an enable signal on the enable line unique to the selected transceiver. Control data is then coupled to the common enabled control data bus for conveyance to the selected transceiver. The transceiver mutes the message data port it may be using and transponds the control data information it receives. When the enable signal is removed, the transceiver unmutes the message data port. Program information is transferred between the cell system controller and cell site controllers as memory blocks which may be retransferred upon detection of a checksum mismatch.
A method for message and control interface between a cell site controller and a plurality of peripheral devices having a message data port and a control data port, comprising the steps of:
