Abstract

PURPOSE:To prevent the interruption of communication during communication and to ensure stable communication system, by giving the priority to a link control, in controlling the link between communication systems. CONSTITUTION:When an audio input of a communication system (a) is outputted to a communication system (b), a a-link audio input 5 and a a-side control input 7 are inputted to a communication controller, a relay 14A is operated by the input 7, and the audio input 5 is applied to the communication system (b) is a b-link audio output 9 via relay contacts 14a1 15a 14b2. At the same time, stray circuit of the a-link audio output 6 is avoided at a relay contact 1412. and it is taken as a b-side output 12 via relay contacts 14a3 15c to the communication system (b) to output a signal operating the communication system (b). Even if a b-side control input 11 is inputted, the operation of a relay 14B is inhibited with a relay contact 14a4. Thus, the relay contacts 14a4, 14b4 inhibit the operation of the relays 14B, 14A respectively, allowing to give priority to the link control and to prevent the intermission of communication.
