    • A telephony services distribution system includes a voice/data server that receives and transmits telephony data in accordance with a suitable digital communication protocol. The voice/data server is associated with a customer premise that supports a number of enhanced telephony devices, which may include wired and/or wireless telephone devices, videophone devices, facsimile devices, or the like. The customer premise may also support any number of conventional POTS telephony instruments. The voice/data server and the enhanced telephony devices communicate signaling data therebetween via a signaling technique such as the V.21 modem protocol. The signaling information conveys data associated with the status of the enhanced telephony devices, calling party and called party identification, characteristics of the incoming and outgoing calls, and/or data related to any number of operating parameters and characteristics of the system. The telephony services distribution system enables a single twisted pair to support calls associated with a plurality of telephone numbers and a plurality of enhanced telephony instruments to receive calls associated with different telephone numbers. The system is capable of regulating, monitoring, and controlling communications in response to a called party identification or a calling party identification.
    • 电话服务分发系统包括根据合适的数字通信协议接收和发送电话数据的语音/数据服务器。 语音/数据服务器与支持多个增强型电话设备的客户端相关联，增强电话设备可以包括有线和/或无线电话设备，可视电话设备，传真设备等。 客户端也可以支持任何数量的常规POTS电话乐器。 语音/数据服务器和增强型电话设备通过诸如V.21调制解调器协议的信令技术在其间传送信令数据。 信令信息传达与增强电话设备的状态，主叫方和被叫方标识，进入和离开呼叫的特征，和/或与系统的任何数量的操作参数和特性相关的数据相关联的数据。 电话服务分配系统使得单个双绞线支持与多个电话号码相关联的呼叫以及多个增强型电话乐器来接收与不同电话号码相关联的呼叫。 该系统能够响应于被叫方标识或主叫方标识来调节，监视和控制通信。

    • A multiplexed data channel telephone system comprising a master station (221) and one or more remote stations (222) is disclosed. Each station (221, 222) is bridged, in a parallel electrical connection, onto a wire-pair (201) that extends from the stations to a telephone switching system. Each station (221, 222) includes a voiceband line interface (110, 310) for connecting to the wire-pair (201) at voiceband frequencies, and a radio frequency line interface (700, 800) for connecting to the wire-pair (201) at radio frequencies. Each station further includes multiplexer and demultiplexer equipment (500, 600) for frequency shifting a data channel between baseband and rf. Amplitude modulation and half-duplex transmission are used in the data channel. Telephone status and control information, including ringing and answer control, are exchanged between controllers (160, 360) via the data channel. Remote stations (222) minimize the amount of equipment required by using the data channel to control common equipment at the master station (221) that interacts with incoming telephone lines (201, 202).
    • 公开了一种包括主站（221）和一个或多个远程站（222）的复用数据信道电话系统。 每个站（221,222）以并联电连接桥接到从站延伸到电话交换系统的有线对（201）上。 每个站（221,222）包括用于以语音频带频率连接到线对（201）的语音频带线路接口（110,310）和用于连接到线对的射频线路接口（700,800） 201）。 每个站还包括用于在基带和rf之间频移数据信道的多路复用器和解复用器设备（500,600）。 在数据通道中使用幅度调制和半双工传输。 电话状态和控制信息，包括振铃和应答控制，经由数据信道在控制器（160,360）之间交换。 远程站（222）使通过数据通道控制主站（221）与进入的电话线（201,202）相互作用的公用设备所需的设备的数量最小化。

    • A communication system is provided for the interconnection of telephones and other instruments capable of communicating via the voice spectrum, the system providing a single transmission line such as a coaxial cable by which full duplex communication is provided between any pair of telephones. Each instrument is coupled to the transmission line by a control unit which includes computer operated transceiver equipment for paging other ones of the control units to initiate a telephonic communication. Each control unit is provided with an identification number and circuitry for recognizing the identification number contained within a paging signal so as to initiate a response. In a separate spectral portion of the transmission line, there are provided sets of analog communication channels each of which has upper and lower spectral portions to provide two-way communication in opposite directions between a pair of telephones engaged in communication. A transmitter and a receiver in each of the control units is provided for the communication of analog signals of both voice and data via the voice channel, each control unit including circuitry for tuning the transmitter and the receiver to the selected channel in accordance with digital data transmitted via the transmission line and specifying a selected one of the voice channels.
