The American National Standards Institute (ANSI) is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.
ANSI T1.413 is a technical standard that defines the requirements for the single asymmetric digital subscriber line (ADSL) for the interface between the telecommunications network and the customer installation in terms of their interaction and electrical characteristics.
Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide.
Carrierless amplitude phase modulation (CAP) is a variant of quadrature amplitude modulation (QAM).
In a telecommunications network or computer network, downstream refers to data sent from a network service provider to a customer.
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions.
Etherloop is a kind of DSL technology that combines the features of Ethernet and DSL.
In telecommunications, ITU-T G.992.1 (better known as G.dmt) is an ITU standard for ADSL using discrete multitone modulation (DMT).
ITU G.992.3 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2 or G.dmt.bis.
ITU G.992.5 (also referred to as ADSL2+, G.dmt.bis+, and G.adslplus) is an International Telecommunication Union standard for asymmetric digital subscriber line (ADSL) broadband Internet access.
High-bit-rate digital subscriber line (HDSL) is a telecommunications protocol standardized in 1994.
Multi-rate symmetric DSL (MSDSL or MDSL) is a proprietary, non-standardized symmetric digital subscriber line technology with a maximum distance of.
In electronics, noise is an unwanted disturbance in an electrical signal.
In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital data on multiple carrier frequencies.
Plain old telephone service or plain ordinary telephone service (POTS) is a retronym for voice-grade telephone service employing analog signal transmission over copper loops.
Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information.
In digital communications, symbol rate, also known as baud rate and modulation rate, is the number of symbol changes, waveform changes, or signaling events, across the transmission medium per time unit using a digitally modulated signal or a line code.
In computer networking, upstream refers to the direction in which data can be transferred from the client to the server (uploading).
Very-high-bit-rate digital subscriber line (VDSL) and very-high-bit-rate digital subscriber line 2 (VDSL2) are digital subscriber line (DSL) technologies providing data transmission faster than asymmetric digital subscriber line (ADSL).
