    • A system and method of communicating voice and data via a local packet network (LPN) to and from a customer site. A remote digital terminal (RDT) is provided at a customer site to interface a plurality of telephone devices and/or data devices (computers or a local area network of computers) with the LPN via a local loop link, such as a Digital Subscriber Line or a wireless local loop. A host digital terminal (HDT) is provided at a control site within or connected to the LPN that coordinates the communication of voice calls between the RDT and a public switched telephone network (PSTN) switch via the LPN and that coordinates the communication of data between the RDT and a data network within or without the LPN. Multiple telephone calls with the customer site can be supported by the remote digital terminal over a single local loop link connected to the LPN. In addition, the HDT can support communication with multiple RDTs.
    • 一种通过本地分组网络(LPN)向客户站点传送语音和数据的方法。 远程数字终端(RDT)被提供在客户站点,以经由本地环路链路(诸如数字用户线路)将多个电话设备和/或数据设备(计算机或计算机的局域网)与LPN接口 或无线本地环路。 主机数字终端(HDT)被提供在LPN内或连接到LPN处的控制站点,该控制站协调通过LPN在RDT和公共交换电话网(PSTN)交换机之间进行语音呼叫的通信,并且协调数据之间的通信 RDT和LPN内部或之外的数据网络。 远程数字终端可以通过连接到LPN的单个本地环路链路支持与客户站点的多个电话。 此外,HDT可以支持与多个RDT的通信。
