ABSTRACT:
A method for networking a plurality of the private branch exchange systems is disclosed in which it is possible to both basically exchange information for the networking by using an ISDN line as a private wire in order to connect mutually a plurality of the private branch exchange systems and transmit/receive necessary information between systems by employing D channel with a line signal and an ISDN protocol and designating the specific channel of B channel to a networking private channel for the networking operation. In addition, one or two channels of several channels between a plurality of the private branch exchange systems can be used for exchanging information, so that the exchange of data between systems operating on a network enables expansion of a system and share of common resources, thereby to improve the efficiency of a system.
