Additional circuit for multimedia communication in buildings

摘要

The circuit includes coupling and uncoupling circuits (13). A reverse channel for a telecommunication network (4) is coupled to a coaxial cable (9) at the transition point (UP) of a broadband distribution network (5). The reverse channel is uncoupled at the connection box (14) of a terminal equipment using the uncoupling circuit. Preferably, the coupling is carried out galvanically, capacitively, inductively or by using active components.
