Abstract
PURPOSE:To make the communication among subscribers A, B, C efficient, by holding the subscriber B when the subscriber A hooks off during the busy state between the caller subscriber A and the called party B and calling the 3rd subscriber C to attain communication. CONSTITUTION:While the subscribers A, B are busy via a network NW 2 and an outgoing trunk TR 4, when the subscriber A hooks on, the outgoing TR 4 detects the hooking. Then the connection between the subscribers A, B is switched to the connection line composed of a NW 2 and an outgoing register 6 and the connection line composed of a call waiting trunk CWT 3, the NW 2 and the outgoing TRs 4, B and a waiting tone is sent from the CWT 3 to the subscriber B. The subscriber A dials the subscriber C by using a call tone from a call register 6. When the subscriber C replies, the subscriber is connected to the subscriber A via the outgoing TR5, the NW 2, the CWT 3, the NW 2 to start the calling. When the subscriber A hooks on again, the subscriber C is kept to the holding state to restart the calling with the subscriber B. Thus, the calling among the three parties is made efficient.
