ABSTRACT:
A digital cordless telephone communicates with a telecommunications network over a wire link and receives first communications signals from and delivers second communications signals to the telecommunications network. The digital cordless telephone includes a cordless fixed part connected to the wire link for receiving the first communications signals from the telecommunications network and for sending the second communications signals to the telecommunications network over the wire link. The cordless fixed part also transmits the first communications signals, together with first control information generated by the cordless fixed part, including a channel identifier indicative of a desired radio frequency communication channel, and receives the second communications signals, together with second control information. The cordless portable part transmits the second communications signals, together with the second control information generated by the cordless portable part, including the channel identifier and a second recipient identification, for receipt by the cordless fixed part, and receives the first communications signals, together with the first control information, from the cordless fixed part. The telephone includes a fixed part memory for receiving the second control information and a portable part memory for receiving the first control information. A fixed part microcontroller generates the first control information, including the channel identifier, and controls the cordless fixed part to transmit the first communications signals over the desired radio frequency communication channel. A portable part microcontroller reads the channel identifier and controls the cordless portable part to transmit the second communications signals over the desired radio frequency communication channel based on the channel identifier.
