PURPOSE:To shorten the time considerably a time till simultaneous notice is started and simultaneous notice is implemented by providing at least two receivers to a terminal station and applying the reception of a selection signal of simultaneous command and the forced processing of talking simultaneously. CONSTITUTION:When simultaneous notice is started from an operation console 1, a line controller 3 of a master station is started via a relay exchange 2. A radio equipment connecting to a control channel 4 receives and sends a signal required for the connection control of a terminal equipment station in the continuous transmission state. The start signal of simultaneous notice connects to a common control section 6 to send information of simultaneous notice. The control section 6 sends information required for the call of simultaneous notice to a channel 4 and a talking channel 5 is used by an object station of simultaneous notice and a prescribed processing is implemented to a busy station and the call is interrupted forcibly. A call signal including the kind of simultaneous notice and object station information or the like is sent to a terminal equipment station 9 through the channel 4 by using an outgoing line 7. A forced interrupt tone is sent through the channel 5 during talking of an object station and forced interrupt is implemented after lapse of several seconds. |
