    • A system and method for transporting a call having call signaling and voiceband user communications through an asynchronous transfer mode system identifies when compression, encryption, or another processing option has been applied to the voiceband user communications. A first signaling processor processes the call signaling to identify a selected first connection and a processing option, such as a compression method, to be applied to the voiceband user communications. The first signaling processor transports a control message to a first interworking unit identifying the selected connection and the selected compression method. The first interworking unit compresses the voiceband user communications with the selected compression method, sets a convergence sublayer indicator bit as an indicator in an asynchronous transfer mode cell, fills the cell with the compressed voiceband user communications, and transports the cell over the selected connection. A second interworking unit receives the asynchronous transfer mode cell, and interworks the cell according to a decompression method for the voiceband user communications if the convergence sublayer indicator bit is set.
    • 用于通过异步传输模式系统传送具有呼叫信令和语音频带用户通信的呼叫的系统和方法识别何时压缩,加密或其他处理选项已被应用于语音频带用户通信。 第一信令处理器处理呼叫信令以识别所选择的第一连接以及应用于语音频带用户通信的诸如压缩方法的处理选项。 第一信令处理器将控制消息传送到标识所选择的连接和所选择的压缩方法的第一互通单元。 第一互通单元使用所选择的压缩方法压缩语音频带用户通信,将会聚子层指示符比特设置为异步传送模式小区中的指示符,用压缩的语音频带用户通信填充小区,并通过所选择的连接传输小区。 第二互通单元接收异步传送模式单元,并且如果设置了会聚子层指示符位,则根据用于语音频带用户通信的解压缩方式来交互单元。

    • A system to interworking a call between a plurality of networks having different formats. The system has a GR-303 system, an integrated services digital network system, a service platform, and an asynchronous transfer mode system. The system has a signaling processor that is adapted to receive the call signaling and to process the call signaling to select a connection to one of the GR-303 system, the integrated services digital network system, the service platform, or the asynchronous transfer mode system. The signaling processor thereby selects the corresponding system on the connection. The signaling processor transports a control message identifying the selected connection. An interworking unit receives the user communications and the control message. The interworking unit converts the user communications from the format in which it was received to the format that is compatible with the selected system. The user communications are then transported on the selected connection.
    • 一种用于在具有不同格式的多个网络之间互通呼叫的系统。 该系统具有GR-303系统,综合业务数字网系统,业务平台,异步传输模式系统。 系统具有信令处理器,其适于接收呼叫信令并处理呼叫信令以选择到GR-303系统,综合业务数字网系统,服务平台或异步传输模式系统之一的连接 。 因此,信令处理器在连接上选择对应的系统。 信令处理器传送标识所选连接的控制消息。 互通单元接收用户通信和控制消息。 互通单元将用户通信从接收的格式转换为与所选系统兼容的格式。 然后在所选择的连接上传输用户通信。
