    Patent number: 5488693
    Abstract: A protocol controls communications between a master unit and a plurality (M) of slave units connected thereto.

The master unit receives uplink messages over a second communication path from the M slave units, the uplink messages having the same format as downlink messages. A third communication path connects between the master unit and the M slave units enabling a first slave unit to signal other slave units of the first slave unit's desire to send information to the master unit.
