Abstract

See full text

A communication channel is established between a master station and one of plural remote stations in a multi-channel access (MCA) cordless telephone system. Access data is transmitted from the master station to all of the remote stations, at the same time, to designate a selected remote station as a representative station. The access data also includes calling data which seeks a response from that representative station. In the absence of a response to the calling data from the previously designated representative station, the station identifying data is changed to designate a new remote station as the representative station. The foregoing process is repeated until a representative station responds to the calling data, whereupon the remote stations are polled, in sequence; and a communication channel is established between the master station and the particular polled station which replies to the polling operation.
