Abstract

A method for increasing upstream bandwidth per cable modem user in a cable communications system that includes a cable modem termination system (CMTS) and a plurality of cable modems is provided. The method permits a cable modem to transmit data to the CMTS on multiple upstream channels simultaneously using a technique called 'channel bonding.' Channel bonding allows smaller bandwidth upstream channels to be bonded together to create a larger bandwidth pipe.
