    • PROBLEM TO BE SOLVED: To eliminate the possibility of incurring malfunction by allowing an exchange to acquire a line of a communication line network through a terminal making a specific dialing to the exchange so as to extend the margin of the communication line network with respect to lines. SOLUTION: In the case that terminal equipment Ai (i=1, 2...) makes a specific dialing, an exchange X acquires a line of a communication line network M so long as number of idle lines in the communication line network M is more than a scheduled line number. In the case that the terminal equipment Ai makes a specific dialing, the exchange X sends a busy tone to the terminal equipment Ai so long as the number of idle lines in the communication line network M is less than the scheduled line number. Moreover, when terminal equipment An other than the terminal equipment Ai connects to a terminal equipment Bn other than a terminal equipment Bi , and idle lines are present in the communication line network M, and the terminal Ai makes a general dialing and the exchange X acquires an idle line of the communication line network M so long as number of idle lines in the communication line network M is less than the scheduled line number, the line acquired by the specific dialing by the terminal equipment An of the communication line network M is open.

    • PURPOSE: To provide a transfer control system for incoming call with which a transferred telephone call can be effectively and efficiently used by providing connection control data in an exchange and transferring information between a remote control transmission part and a remote control reception part through a common line signal network for changing the connection control data. CONSTITUTION: In relation to data storage, an exchange 1 is provided with a start data storage part 21, incoming data storage part 23, transfer data storage part 25 and security data storage part 39. Further, as function parts related to incoming call transfer control, the exchange 1 is provided with a start control part 27, transfer control part 29 and incoming control part 31. Besides, in relation to data control, the exchange 1 is provided with a cascade connection control part 33, data control part 35 and remote control reception part 37. Thus, even when any fault is generated at a service control point, the connection control data can be changed from the terminal at the destination. Besides, when the number of input errors is totally more than the prescribed number of times, remote control is inhibited excepting for contracted persons so that the illegal usage of the third person can be prevented.
