Patent number: 6324188Abstract: An input voice signal is passed from a voice signal encoding unit to a voice signal compressing unit so that it is encoded and compressed. No transmission of a silence signal within the voice signal to a multiplexing unit is performed in a silence signal eliminating unit. A multiplexing unit multiplexes the voice signal with a data to be transmitted which has been passed via a data terminal control unit and a data terminal control unit from a data terminal and is transmitted to a communication line via the transmission control unit. Lapse of a time-out period of time which is present in a timer is detected in a silence signal inserting unit so that a silence signal is generated and is reproduced in a voice signal decompressing unit and a voice signal decoding unit.Type: GrantFiled: April 29, 1998Date of Patent: November 27, 2001Assignee: Sharp Kabushiki KaishaInventor: Keisuke Tsuji
