Abstract:
A fast C-plane transmission mode circuit utilized within a cordless telephone handset of a digital enhanced cordless telecommunications (DECT) system, said circuit comprising:a first buffer device coupled to receive and store control data utilized within said DECT system, said first buffer device outputs a capacity signal for indicating an amount of control data stored within said first buffer device;a second buffer device coupled to receive and store user data utilized within said DECT system;a multiplexer circuit coupled to said first and said second buffer devices to output said control data or said user data;a silence detector circuit coupled to receive said user data, said silence detector circuit for generating an output signal when a period of silence is detected within said user data, wherein said output signal controls whether said multiplexer circuit outputs said control data or said user data, said silence detector circuit coupled to receive said capacity signal, said silence detector circuit generating said output signal to control said multiplexer circuit such that said amount of control data stored within said first buffer device remains below a predetermined limit; anda DECT channel buffer circuit for receiving said control data and said user data from said multiplexer circuit and for encoding said control data and said user data for transmission within said DECT system, wherein said control data is transmitted in accordance with a fast C-plane transmission mode.
