<P>PROBLEM TO BE SOLVED: To achieve a single digital communication link between a system-side circuit and a line-side circuit in a DAA, capable both of carrying data signals and transferring a substantial amount of power to the line-side circuit. <P>SOLUTION: The invention comprises a system-side interface circuit, a line-side interface circuit, and an isolation barrier including a transformer. Each interface circuit is capable of connection to an upstream communication circuit (either on line-side or system-side), from which the interface circuit may receive data signals to be transmitted across the isolation barrier to the other interface circuit, and to which the interface circuit may pass data signals received across the isolation barrier from the other interface circuit. The line-side interface circuit may further include a rectifier and a storage device. <P>COPYRIGHT: (C)2013,JPO&INPIT |
