APPARATUS FOR SWITCHING B-CHANNEL DATA AND TERMINAL FOR ISDN THEREWITH

摘要

PURPOSE: An apparatus for switching B-channel data and a terminal for ISDN(Integrated Service Digital Network) therewith are provided to allow the terminal to have various additional functions by switching freely the B-channel data made in feely various digital data generating apparatuses within the terminal and by transmitting the data to the apparatuses. CONSTITUTION: A B-channel data switching apparatus(101) is connected with a plurality of B-channel data generating/receiving apparatuses(102) by using the same interfaces. The B-channel data switching apparatus(101) is connected with a communication network matching apparatus for transmitting the B-channel data, and connected with a central processing apparatus(104) for designating the path connection of the data. The B-channel data generating/receiving apparatus(102) generates and receives the B-channel data within the terminal. The communication network matching apparatus(103) transmits the data generated in the terminal via the communication network, and receives the data transmitted via the communication network.
