Patent number: 8472433Abstract: Voice communications apparatus is connected to a general subscriber telephone set or a broadband telephone set, to communicate over the public switched telephone network. The apparatus includes a filter converting signals such as to satisfy signal conditions prescribed for the telephone network. The apparatus also includes a terminal class determiner for determining the class of the telephone set connected, and a circuit for changing at least the sampling frequency at which the analog signals from the telephone set are sampled. This establishes high quality in broadband voice communications. The terminal class determiner may automatically determine the class of the telephone set at any timing of a call sequence by detecting a band component of the signals from the telephone set, a predetermined frequency of a signal intermittently transmitted from the telephone set or the characteristics of the telephone set.Type: GrantFiled: April 14, 2010Date of Patent: June 25, 2013Assignee: Oki Electric Industry Co., Ltd.Inventors: Shinji Usuba, Hiroshi Kuboki, Hiromi Aoyagi

Patent number: 7983908Abstract: A noise-canceling device of a voice communication terminal that removes noise elements included in received voice signals. The device comprises: a digital filter array that exhibits filter qualities in response to a coefficient setting signal showing each supplied arrays of filter coefficients, and includes a first-stage filter that receives the received voice signals as well as multiple later-stage filters connected thereto in a straight line; a filter qualities designator that generates input designation that designates each qualities of the multiple digital filters forming the digital filters array; and a filter coefficient setter that retains multiple arrays of filter coefficients, extracts a filter coefficient array corresponding to the designation input from among the multiple filter coefficient arrays, and supplies to each multiple digital filters.Type: GrantFiled: March 15, 2007Date of Patent: July 19, 2011Assignee: Oki Electric Industry Co., Ltd.Inventors: Hiroshi Kuboki, Kenichi Kurihara

Patent number: 7706354Abstract: A telephone switching system includes line packages and a switch unit allowing a path to be established between the line packages. At least one line package is interconnected to, e.g. a broadband-adaptive unit, and is adaptive to both of a first coding rule expected of the switch unit and a second coding rule higher in compression ratio than the first coding rule. The broadband-adaptive line package, monitoring the coding rule of another line package connected thereto, adapts itself to the first coding rule if the other line package is adaptive only to the first coding rule, or adapts itself to the second coding rule if the other line package is adaptive to both of the first and second coding rules.Type: GrantFiled: November 16, 2004Date of Patent: April 27, 2010Assignee: Oki Electric Industry Co., Ltd.Inventors: Shinji Usuba, Hiroshi Kuboki

Patent number: 7672296Abstract: A VoIP system has plural CPE units connected to an IP network as parties to be connected with each other. Each CPE unit is composed of a VoIP-IF circuit and an audio codec circuit. The VoIP-IF circuit executes at least one of the coding process to the first audio frequency signal and the restoration process to the media information to transmit the media information generated by the process to the party connected and restore the first audio frequency signal from the media information supplied from the party connected to output it. The audio codec circuit performs at least one of the sending of the received music data to the party and the conversion of the music data supplied from the party into the second audio frequency signal.Type: GrantFiled: November 23, 2004Date of Patent: March 2, 2010Assignee: Oki Electric Industry Co., Ltd.Inventors: Hiromi Aoyagi, Yumiko Araki, Shinji Usuba, Hiroshi Kuboki
