PURPOSE:To store many terminals by selecting data link controllers according to inputted first, second, and third control information. CONSTITUTION:When B channel packet communication is requested, it is discriminated whether a B channel data link processor 6 has an available data link control circuit LSI or not. If it has an available control circuit LSI, the identification number is sent as first control information to a network processor 23. When the terminal number of the other party of communication is inputted and this terminal 1 having this number is a terminal l for ISDN interface an identification number set correspondingly to an available control circuit LSI is sent as second control information to the processor 23 if the processor 6 has the available control circuit LSI. When the terminal is a terminal 2 for non-ISDN interface, the identification number of the control circuit LSI corresponding to this terminal is sent as third control information to the processor 23. Since the processor 23 has the function of a selective part and controls the processor 6 or a non-ISDN interface subscriber device 9 based on the control information, many various terminals are stored. |
