The Cable Modem Termination System (CMTS) is the major component of the headend. It interfaces to the cable network, the backbone data network, and several support systems. The CMTS also controls the configuration, registration, and media access of all the cable modems under its control, and determines who gets to transmit when, and for how long.
A device deployed in cable operator head-end buildings. The CMTS is connected to the radio frequency (RF) modulator receiver and converts cable modem and MTA data into packets for transport to IP data networks.
