DOCSISData Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide cable Internet access over their existing hybrid fiber-coaxial (HFC) infrastructure.
Passive optical networkA passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. In this use, a PON has a point-to-multipoint topology in which an ISP uses a single device to serve many end-user sites using a system such as 10G-PON or GPON.Cable television headendA cable television headend is a master facility for receiving television signals for processing and distribution over a cable television system. Under Federal Communications Commission regulations, a cable operator must designate a principal headend for regulatory purposes. A headend facility may be staffed or unstaffed and is typically surrounded by some type of security fencing.DSLAMA digital subscriber line access multiplexer (DSLAM, often pronounced DEE-slam) is a network switch often located in telephone exchanges, that multiplexes multiple downstream links from digital subscriber line (DSL) customers interfaces to an upstream interface. Its cable internet (DOCSIS) counterpart is the cable modem termination system.BigBand NetworksBigBand Networks was a corporation headquartered in Redwood City, California, that opened in 1999 and specialized in selling multimedia technologies to cable television multi-system operators. It had its IPO on the Nasdaq in 2007, which was met with controversy when a class-action lawsuit alleged that the company violated the Securities Act of 1933. The company was acquired as a division within Arris Group in 2011.
Router (computing)A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet. Routers perform the traffic directing functions on the Internet. A router is connected to two or more data lines from different IP networks. When a data packet arrives on a line, the router reads the network address in the packet header to determine the destination.
Cable Internet accessForm of broadband Internet access In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband internet access which uses the same infrastructure as cable television. Like digital subscriber line (DSL) and fiber to the premises, cable Internet access provides network edge connectivity (last mile access) from the Internet service provider to an end user.
Voice over IPVoice over Internet Protocol (VoIP), also known as IP telephony, is a set of technologies used primarily for voice communication sessions over Internet Protocol (IP) networks, such as the Internet. VoIP enables voice calls to be transmitted as data packets, facilitating various methods of voice communication, including voice and video conferencing applications and appliances and VoIP phones.
Digital subscriber lineDigital subscriber line (DSL), originally digital subscriber loop, is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.Optical line terminationAn optical line termination (OLT), also called an optical line terminal, is a device which serves as the service provider endpoint of a passive optical network.Hybrid fiber-coaxialHybrid fiber–coaxial (HFC) is a broadband telecommunications network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s. In a hybrid fiber–coaxial cable system, television channels are sent from the cable system's distribution facility, the headend, to local communities through optical fiber subscriber lines.ADC TelecommunicationsADC Telecommunications, Inc. was a communications company in Eden Prairie, Minnesota, a southwest suburb of Minneapolis. It was acquired by TE Connectivity (Tyco Electronics) in December 2010 and ceased to exist as a separate entity. ADC products were sold by CommScope after it acquired the Broadband Network Solutions business unit (including ADC) from TE Connectivity in August 2015.*As an Amazon Associate I earn from qualifying purchases.
