ABSTRACT:
A communication control method of a communication system including a network, such as an ISDN network, and a plurality of main interconnection buses connected to the network through respective connecting units. A plurality of terminal apparatuses are operatively connected to each of the main interconnection buses. Each bus is provided with a signal channel, which is shared by the plurality of terminal apparatuses connected to the bus for call connection with the network, and at least one information channel for transmission of information in a multiplex format. In accordance with the principle of the present invention, when all of the information channels are occupied or in use, the signal channel is temporarily used as an additional information channel to thereby allow the other terminal apparatuses to carry out transmission of information.
