Abstract

PURPOSE:To attain the state transition of interrupted calls while maintaining the interruption state by connecting an interrupted terminal device, an interrupting terminal equipment and its opposite terminal equipment via a mixing trunk when an interruption call takes place in the interrupted terminal equipment where a call is set. CONSTITUTION:When the call is set while the interrupted terminal equipment 4 and the opposite terminal equipment 5 are connected via a channel network 2, the interruption terminal equipment 6 operates a function key to raise an interruption request. A central control unit 1 detects the operation to connect the terminal equipment 4 to a terminal 7j of a mixing trunk MXT7 as an interruption call processing and connect the terminal device 5 to a terminal 7i and the terminal equipment 6 to a terminal 7k. The controller 1 sets a sender terminal number MEN corresponding to a terminal number EN of call state memories CDM2, 1 managing respectively an interruption call and an interrupted call to a storage device 3, sets a prescribed number to a terminal number conversion table so as to control independently the CDM1, 2 respectively. Thus, the state of the interrupted call is transited while the interrupting state is maintained by changing the connection of the MXT7 depending on the state of the interrupted call.

Telling is widely used. In such a case, the status of the interrupted call (hereinafter referred to as the interrupted call) is as follows:
The call does not always remain busy; for example, the terminal being interrupted and the terminal on the other end of the conversation (hereinafter referred to as the connected terminal) may place a money call to another terminal, and the terminal receiving the interruption may hear hold music. Cases in which the state changes, such as listening to a message, are also considered.

■　割込呼設定後も被割込呼の状態遷移を許容し、状態
遷移後は割込呼を終了させる。■ Allow the state of the interrupted call to change even after setting the interrupt call, and terminate the interrupt call after the state transition.

■　割込呼設定後も被割込呼の状態遷移を許容し、状態
遷移に伴い割込呼を再設定して割込状態を維持する。■ Allow the state of the interrupted call to change even after setting the interrupt call, and maintain the interrupt state by resetting the interrupt call in accordance with the state transition.
