Abstract

PURPOSE:To make a plurality of calls at the same time, by providing a speaker for common use for accessing to a called party at a plurality of paging trunks, in a speaker paging system. CONSTITUTION:When a SUB A dials the number for speaker paging call, a common controller MKR selects and connects a speaker paging trunk PGT. A MB relay is operated at a trunk in trunk PGT(NO1)-(NOn), the selection route of the trunk given in the trunk by a contact mb deg. is cut off and it can not be selected and connected from the MKR. The SUB A is connected to a speaker to call a called party. When the called party responds, the MKR makes selection and connection of the trunk PGT at a lead TC and F1. Next, a relay BY is operated and the connection path at the speaker side of the SUB A is disconnected with contacts by<3>, by<4> to enable to have communication between the SUB A and the SUB B.
