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.

Description

technical field [0001] The present invention relates to a method of transmitting data in a data communication system, such as but not limited to a cable television communication system. Background technique [0002] Conventional cable television communication systems typically use a cable modem headend that manages communications with multiple cable modems. The headend defines the upstream operating characteristics that enable the cable modem to send the carrier signal upstream to the headend. This upstream can include multiple channels that can be assigned to cable modems. These channels are independent of each other by operating at different frequencies. [0003] One or more cable modems transmit carrier signals carrying requests and / or data to the headend using designated frequency channels. The demodulator at the headend receives these uplink signals, and the modulator is connected to the physical spectrum, and the physical spectrum is connected to the cable TV modem ...
