Cable modem termination system
A cable modem termination system (CMTS, also called a CMTS Edge Router) is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
A CMTS provides similar functions to a DSLAM in a digital subscriber line or an optical line termination in a passive optical network.
