Abstract

PURPOSE:To allow a path switching request of each control subscriber not to disturb other path changeover by allowing the generation of a new call waiting execution group overlappingly partilly when an incoming call comes to the call waiting execution group. CONSTITUTION:A central control unit 12 reads a subscriber SUB 3 in a main storage device 13 and a linkage call information memory CLM2 by a path switching request from a control subscriber SUB 3 of an additional group CWG 2 to recognize it that a subscriber SUB 2 is a duplicated call waiting and a control right is in the additional group CWG 2. Thus, the additional group CWG 2 opens a path 203 and closes a path 304 and the subscribers SUB3, 4 enter the talking state. Simultaneously, path switching information is sent to a basic group CWG 1, its reception is set additionally to a control information MCWB at the subscriber SUB 3 in the call information memory CLM1 and the subscriber SUB 2 is made into the holding state. Similarly, the path is switched in response to the state of the opposite group.
