Cable Modem Termination Systems (CMTS)

Introduction

The CMTS is a Cisco Universal Broadband Router (uBR) with features that enable it to communicate with a Hybrid Fiber Coaxial (HFC) Cable network via a Cisco MCxx cable modem card. Cisco MCxx cable modem cards allow you to connect cable modems on the HFC network to a Cisco uBR7200, uBR7100 or a uBR10k in a Community Antenna Television (CATV) headend facility. The modem card provides the interface between the Cisco uBR protocol control information (PCI) bus and the radio frequency (RF) signal on the DOCSIS HFC network.
