    • To provide a switching system with telephone switching function mainly on the basis of hardware processing by using isochronous channel which is a real time communication channel. The switching system comprises a gateway node connected with ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network), and one or more extension nodes, and a serial bus such as IEEE 1394 bus. The gateway node transforms data rate of outside line into data rate of extension node, and the other way around, and secure a seamless communication channel. Concretely, the gateway node secures an isochronous channel, according to a request from the extension nodes or the outside line, and executes switching such as transfer or reservation. A resource manager holds a table for managing the gateway node and extension node.
    • 提供具有电话交换功能的交换系统,主要通过使用作为实时通信信道的同步信道在硬件处理的基础上。 交换系统包括与ISDN(综合业务数字网络)和PSTN(公共交换电话网络)连接的网关节点,以及一个或多个分机节点和诸如IEEE 1394总线的串行总线。 网关节点将外线的数据速率转换为扩展节点的数据速率,另一方面,确保无缝通信信道。 具体地,网关节点根据来自扩展节点或外线的请求来确保同步信道,并执行诸如传送或预留之类的切换。 资源管理器保存用于管理网关节点和扩展节点的表。

    • The invention provided a a communication method, a voice transmission apparatus and a voice reception apparatus by which, in communication through a non-guarantee type network, deterioration in voice, unnatural interruption of language, jump of voice and so forth which arise from unstable communication or a load variation can be eliminated to the utmost to allow conversation which can be recognized readily and conversation by natural voice can be achieved. Voice of a talking person is inputted through a voice to electric conversion element such as a microphone to a voice inputting and outputting element, by which the voice signal is converted into a corresponding voice data electric signal. The voice data are inputted to a speech recognition and conversion section, by which they are converted into a character code data signal by speech synthesis.
    • 本发明提供了一种通信方法,语音发送装置和语音接收装置,其通过非保证型网络进行通信,由不稳定的通信引起的语音恶化,语言的不自然的中断,语音的跳跃等, 可以最大程度地消除负载变化,以允许可以容易地认出的对话,并且可以实现通过自然语音的对话。 讲话者的声音通过语音输入到诸如麦克风的电转换元件到语音输入和输出元件,通过该语音输入和输出元件将语音信号转换成相应的语音数据电信号。 语音数据被输入到语音识别和转换部分,通过语音合成将它们转换成字符代码数据信号。
