Abstract

An xDSL (x-Digital Subscriber Line) signal is multiplexed with POTS on a twisted pair between a subscriber modem and line termination equipment in a shelf that also includes network termination equipment for connection to a broadband network. The line termination and network termination equipment are interconnected by a bus internal to the shelf for providing subscriber access. Separate lowpass filters are provided at each end of a twisted wire pair between the shelf and each subscriber equipment. A shelf can be used as a hub for connecting to a remote shelf that includes the line termination equipment for connection to subscribers.
