Abstract

A data communications apparatus and method to allow a single central site modem (18) to handle numerous DSL multiple modems (51) connected to a single subscriber line (27). The data communications apparatus and method that are implemented via logic that performs selected program routine sequences. These sequences include the transmission of packets from multiple DSL modems (51) directly connected, at a premises, to a single subscriber line to simultaneously provide data sessions with a single DSL modem (18) at the central office (11).
