    • A switching system (14) at a customer premises communicates information associated with one or more subscribers. The switching system (14) includes multiple subscriber line ports (17) for communicating xDSL signals with subscribers, the xDSL signals containing both data signals and POTS voice signals. A logical port (20) communicates data signals and packetized voice signals from the subscribers with a central office, the switching system (14) converting between the POTS voice signals of the subscriber lines (16) and the packetized voice signals of the logical port (20). A LAN port (21) communicates data signals with a server complex (23) using a LAN (22) to provide data services to the subscribers. The switching system (14) may include a switch (32) that receives voice signals on a first virtual circuit (VC), switches the voice signals out of the switching system (14) on the first VC, and also communicates received data signals for routing. A router (32) within the switching system (14) may receive the data signals from the switch (32) on a second VC, determine a third VC for the data signals, and route the data signals to the switch (32) on the third VC for communication out of the switching system (14) on the third VC.
    • 客户驻地的交换系统(14)传送与一个或多个订户相关联的信息。 交换系统(14)包括用于与用户通信xDSL信号的多个用户线路端口(17),xDSL信号包含数据信号和POTS语音信号。 逻辑端口(20)将来自订户的数据信号和分组语音信号与中心局通信,交换系统(14)在用户线路(16)的POTS语音信号与逻辑端口的分组语音信号 20)。 LAN端口(21)使用LAN(22)将数据信号与服务器复合体(23)进行通信,以向用户提供数据服务。 交换系统(14)可以包括在第一虚拟电路(VC)上接收语音信号的开关(32),将语音信号从第一VC上的交换系统(14)切换出来,并且还传送接收到的数据信号以供 路由。 交换系统(14)内的路由器(32)可以在第二VC上接收来自开关(32)的数据信号,确定数据信号的第三VC,并将数据信号路由到交换机(32)上 用于第三VC的交换系统(14)的通信。
