    Abstract: A system (10) and method for simultaneously enabling a voice and a data session has a voice data modem VDM (200), coupleable to a data port (255), a voice jack (240), and a telco jack (280). The data port (255) is connected to data terminal equipment, DTE (100), the voice jack (240) is connected to a telephone, and the telco jack (280) is connected to a telephone network (120). The data ports of each VDM are connected to other DTE (180-182), the voice jacks are connected to first extensions of a network, and telco jacks are connected to different, second extensions of the network. The VDM (200) receives multiplexed voice and data over a single, first extension of the network through the telco jack (280), demultiplexes and decompresses the voice and data, transmits or retransmits the voice separately from the data over a second network extension via the voice jack (240), and transmits the data to DTE through a data port or interface (255).

    Abstract translation: 用于同时启用语音和数据会话的系统(10)和方法具有可耦合到数据端口(255),语音插孔(240)和电话插孔(280)的语音数据调制解调器VDM(200)。 数据端口(255)连接到数据终端设备DTE(100),语音插孔(240)连接到电话,电话插孔(280)连接到电话网络(120)。 每个VDM的数据端口连接到其他DTE(180-182),语音插孔连接到网络的第一个扩展,电信插孔连接到网络的不同的第二个扩展。 VDM(200)通过电话插孔(280)在网络的单个第一分机上接收复用的语音和数据,解复用和解压缩语音和数据,通过第二网络分机通过第二网络分机从数据中分离地发送或重新发送语音 语音插孔(240),并通过数据端口或接口(255)将数据发送到DTE。
