The benefits of IDSL over ISDN are that IDSL provides always-on connections and transmits data via a data network rather than the carrier's voice network. [1] IDSL also avoids per-call fees by being generally billed at a flat-rate. IDSL is not available in all countries. ISDN digital subscriber line (IDSL) is a cross between ISDN and xDSL.
The letter G in G.fast stands for the ITU-T G series of recommendations; fast is a recursive acronym for fast access to subscriber terminals. [9] Limited demonstration hardware was demonstrated in mid-2013. [10] The first chipsets were introduced in October 2014, with commercial hardware introduced in 2015, and first deployments started in 2016 ...
Single-pair high-speed digital subscriber line (SHDSL) is a form of symmetric digital subscriber line (SDSL), a data communications technology for equal transmit and receive (i.e. symmetric) data rate over copper telephone lines, faster than a conventional voiceband modem can provide.
Annex J is a specification in ITU-T Recommendations G.992.3 and G.992.5 for all digital mode ADSL with improved spectral compatibility with ADSL over ISDN, which means that it is a type of naked DSL which will not disturb existing Annex B ADSL services in the same cable binder.
ITU G.992.3 is an ITU (International Telecommunication Union) standard, also referred to as ADSL2 or G.dmt.bis.It optionally extends the capability of basic ADSL in data rates to 12 Mbit/s downstream and, depending on Annex version, up to 3.5 Mbit/s upstream (with a mandatory capability of ADSL2 transceivers of 8 Mbit/s downstream and 800 kbit/s upstream).

Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. [1] Work on the standard began in 1980 at Bell Labs and was formally standardized in 1988 in the CCITT "Red ...

This is a list of very-high-bit-rate digital subscriber line (VDSL) and very-high-bit-rate digital subscriber line 2 (VDSL2) deployments.. The term VDSL can either refer specifically to ITU-T G.993.1 (first generation VDSL, officially abbreviated as "VDSL", unofficially also called "VDSL1"), or may be used as an umbrella term for both ITU-T G.993.1 and ITU-T G.993.2 (second generation VDSL ...
