    ADSL - Wikipedia

    https://en.wikipedia.org/wiki/ADSL

    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. ADSL differs from the less common … See more

    Overview

    ADSL works by using spectrum above the band used by voice telephone calls. With a DSL filter, often called splitter, the frequency bands are isolated, permitting a single telephone line to be used for both ADSL service and … See more

    Currently, most ADSL communication is full-duplex. Full-duplex ADSL communication is usually achieved on a wire pair by either frequency-division duplex (FDD), echo-cancelling duplex (ECD), or time-division duplex (TDD). FDD uses two separate … See more

  2. Digital subscriber line - Wikipedia

    https://en.wikipedia.org/wiki/Digital_subscriber_line

    Digital 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.
    DSL service can be delivered simultaneously with wired telephone service on the same telephon…

          What is ADSL (asymmetric digital subscriber line)?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. ADSL differs from the less common symmetric digital subscriber line (SDSL).

          What is the difference between ADSL and SDSL?ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises ( downstream) than the reverse ( upstream ).

          en.wikipedia.org/wiki/ADSL
          What is the bandwidth of ADSL over POTS?With commonly deployed ADSL over POTS (Annex A), the band from 26.075 kHz to 137.825 kHz is used for upstream communication, while 138–1104 kHz is used for downstream communication. Under the usual DMT (Discrete Multitone Modulation) scheme, each of these is further divided into smaller frequency channels of 4.3125 kHz.

          How far can ADSL be installed?ADSL is generally only installed for short distances from the telephone exchange (the last mile ), typically less than 4 kilometres (2.5 mi), [2] but has been known to exceed 8 kilometres (5 mi) if the originally laid wire gauge allows for further [clarification needed] distribution.
