    摘要： A signal processing system which discriminates between voice signals and data signals modulated by a voiceband carrier. The signal processing system includes a voice exchange, a data exchange and a call discriminator. The voice exchange is capable of exchanging voice signals between a switched circuit network and a packet based network. The signal processing system also includes a data exchange capable of exchanging data signals modulated by a voiceband carrier on the switched circuit network with unmodulated data signal packets on the packet based network. The data exchange is performed by demodulating data signals from the switched circuit network for transmission on the packet based network, and modulating data signal packets from the packet based network for transmission on the switched circuit network. The call discriminator is used to selectively enable the voice exchange and data exchange.

    摘要翻译： 一种信号处理系统，其识别语音信号和由语音频带载波调制的数据信号。 信号处理系统包括语音交换，数据交换和呼叫鉴别器。 语音交换能够在交换电路网络和基于分组的网络之间交换语音信号。 信号处理系统还包括能够在基于分组的网络上与未调制的数据信号分组交换由交换电路网络上的语音带载波调制的数据信号的数据交换。 通过解调来自交换电路网络的数据信号进行数据交换，以在基于分组的网络上进行传输，并且调制来自基于分组的网络的数据信号分组，以便在交换电路网络上传输。 呼叫鉴别器用于选择性地启用语音交换和数据交换。
