Abstract

PURPOSE:To share a call controlling and processing part and to facilitate the generation of a call connected state control program by separating the state management of a line protocol which transits in accordance with the control signal inherent to a line and that of a call which is independent of the kind of the line protocol. CONSTITUTION:A line protocol control signal from a subscriber terminal 21 requests a switch control system 14 to connect a main switch 11 by a first call connection control system 12, and call connection information is given and received to form a second call connection control system 13 accommodating the subscriber terminal 22 of a communication opposite as well. In respective call connection control systems 12 and 13, a task in which a micro processor 201 controls a multiple virtual space, analyzes the line protocol control signal from the subscriber line and controls the state of the line protocol and which is allotted at every line, and a task which gives and receives the control signal required for the call connection of the line between the other call control processor and which is allotted at every call controlling the call state are generated.
