Abstract

See full text

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