Abstract

A communication system (10) includes a number of subscribers (12) coupled to a station (14) using twisted pair subscriber line (16). In one embodiment, the station (14) includes a telephone switch (56) that provides telephone service to the subscriber (12), and a communication server (58) having a number of XDSL modems (160) that provide data service to the subscriber (12). The communication server (58) allows over subscription of data service to subscribers (12).
