Abstract

Integrated broadcast system It serves to consolidate signals from LAN communications and other communications without multiplexing. The first LAN communicator is connected to the second LAN communicator through two lines (10,20). ) Is connected to the midpoint intersection. Of the coils of the pot - electrical converter (50,51) on the side of the coaxial cable To consolidate the communication signal from the first broadcaster on the LAN signal and separate the telephone communication from the LAN signal at the midpoint junction. Power transformers (50,51) have one integrated / split circuit. The second relay-relay, such as the switching terminal (112), is connected to the center-winding junction of the transformer (60,61) on the side of the coaxial cable to integrate the communication signal from the second photocopier on. The LAN signal and the communication signal is isolated from the LAN signal at the semi-central junction. The transformer (60,61) consists of a second integrated / split circuit.
