	Cable modem termination system - Wikipedia, the free encyclopedia
		A cable modem termination system or CMTS is equipment typically found in a cable company's headend and is used to provide high speed data services, such as Cable Internet or Voice over IP, to cable subscribers.
		Traffic destined for the cable modem from the Internet, known as downstream traffic, is carried in IP packets encapsulated in MPEG packets.
		Upstream data (data from cable modems to the headend or Internet) is carried in Ethernet frames modulated with Quadrature Phase Shift Keying.

	DSL vs Cable modem
		Cable modems, which allow users to connect using the cable television network, seem to be first out of the gate with broader availability and lower costs with some concern about the security issues.
		Cable modems are designed to take advantage of the "broadband" cable infrastructure enabling peak connection speeds over 100 times faster than traditional dial-up connections.
		Because some cable networks are suited for broadcast television services, cable modems may use either a standard telephone line or a QPSK/16 QAM modem over a two-way cable system to transmit data upstream from a user location to the network.

	cable modem termination system - a Whatis.com definition - see also: CMTS
		A cable modem termination system (CMTS) is a component that exchanges digital signals with cable modems on a cable network.
		A data service is delivered to a subscriber through channels in a coaxial cable or optical fiber cable to a cable modem installed externally or internally to a subscriber's computer or television set.
		One television channel is used for upstream signals from the cable modem to the CMTS, and another channel is used for downstream signals from the CMTS to the cable modem.

	AusCERT - ESB-2002.286 -- Cisco Security Advisory -- Cable Modem Termination System Authentication Bypass
		The first issue involves cable modems not manufactured by Cisco that allow a configuration file to be downloaded from an interface that is not connected to the network of the cable modem's service provider.
		The cable shared-secret command in Cisco IOS Software configures a password that is included in the MD5 hash that produces the MIC; without the password, it is computationally infeasible to produce the correct matching MIC, and the cable modem is prevented from registering with the service provider's network.
		Some non-Cisco cable modems may be running older versions of software that save a local copy of the configuration information and use that cached copy at registration time instead of obtaining the actual file from a TFTP server.

	What is CMTS? - A Word Definition From the Webopedia Computer Dictionary (Site not responding. Last check: 2007-10-15)
		Short for cable modem termination system, a system of devices located in the cable head-end that allows cable television operators to offer high-speed Internet access to home computers.
		The CMTS sends and receives digital cable modem signals on a cable network, receiving signals sent upstream from a user's cable modem, converting the signals into IP packets and routing the signals to an Internet Service Provide for connection to the Internet.
		Cable modems cannot communicate directly with each other; they must communicate by channeling their signals through the CMTS.

		Another benefit of the cable modem for Internet access is that, unlike ADSL, its performance doesn't depend on distance from the central cable office.
		On the upstream side, the burst modulator in cable modems is programmed with the distance from the head-end, and provides the proper signal strength for accurate transmission.
		IDC predicts that the total number of households connected via cable modem will grow to nearly 9 million by 2003.

	Cisco CMTS Feature Guide - DHCP, ToD, and TFTP Services for the Cisco Cable Modem Termination System [Cisco ...
		Although cable modems do not need to successfully complete the ToD request before coming online, this allows them to add accurate timestamps to their event logs so that these logs are coordinated to the clock used on the CMTS.
		This allows the cable modems and CPE devices to accurately timestamp their Simple Network Management Protocol (SNMP) messages and error log entries, as well as ensure that all of the system clocks on the cable network are synchronized to the same system time.
		This is because BPI+ authorization requires that the CMTS and cable modem verify the timestamps on the digital certificates being used for authentication.

		Key challenges in supporting broadband cable services are providing differentiated service, accommodating new users and new applications, and maintaining a reliable, high-performance service.
		To meet these challenges, the major cable system companies, referred to as multiple system operators (MSOs), have implemented a standard technical specification called the data over cable service interface specification (DOCSISTM 1.1), which increasingly requires quality of service (QoS) features and high-reliability, high-availability infrastructures, including new-generation cable modem termination systems (CMTSs).
		A combination of programmable logic and a high-performance processor satisfies these requirements, allowing cable modem manufacturers such as Cadant, Inc. the option to easily modify their product designs and the products themselves, if needed, to meet changing conditions.

	Business Wire: Yankee Group Reports Cable Modem Termination System Vendors Have Sights Set on Cisco
		The new Yankee Group Report, "CMTS Vendors Setting Their Sights on Cisco," reveals that although Cisco Systems is the dominant first-generation, cable modem termination system (CMTS) vendor in the market today, the first-generation of CMTS platforms based on the DOCSIS standard did not address the need to offer advanced services such as VoIP.
		According to Broadband Access Technologies analyst Lindsay Schroth: "Cable operators have recognized that it is essential to expand both their subscriber base and service offerings to maintain profitability, and the equipment in place today will not be able to handle a large expansion of subscribers or advanced offerings."
		Although the difficult economy is causing cable operators to move more slowly than anticipated with the rollout of these next generation platforms, upgrading to advanced platforms is an essential strategy for them.
