2. G.992.1 - Wikipedia

   en.wikipedia.org/wiki/G.992.1

   In telecommunications, ITU-T G.992.1 (better known as G.dmt) is an ITU standard for ADSL using discrete multitone modulation (DMT). G.dmt full-rate ADSL expands the usable bandwidth of existing copper telephone lines, delivering high-speed data communications at rates up to 8 Mbit/s downstream and 1.3 Mbit/s upstream.

3. ADSL - Wikipedia

   en.wikipedia.org/wiki/ADSL

   ADSL initially existed in two versions (similar to VDSL), namely CAP and DMT. CAP was the de facto standard for ADSL deployments up until 1996, deployed in 90 percent of ADSL installations at the time. However, DMT was chosen for the first ITU-T ADSL standards, G.992.1 and G.992.2 (also called G.dmt and G.lite respectively). Therefore, all ...

4. Rate-Adaptive Digital Subscriber Line - Wikipedia

   [4] [5] RADSL supports downstream data rates of up to approximately 8 Mbit/s, upstream data rates up to approximately 1 Mbit/s, and can coexist with POTS voice on the same line. [ 5 ] RADSL allows rate-adaptation while the connection is in operation — rate-adaptation during connection setup is possible in many other DSL variants, including G ...

5. ANSI T1.413 Issue 2 - Wikipedia

   Taken with the baud rate of 4,000 per second per subcarrier, the maximum throughput is just over 1.5 Mbit/s. In order to combine voice telephone service with downstream and upstream ADSL signals the bandwidth is split into discrete parts using frequency-division multiplexing (FDM). In this case: 0–4 kHz is for voice, 26–138 kHz is the ...

6. G.992.3 - Wikipedia

   en.wikipedia.org/wiki/G.992.3

   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).

7. Digital subscriber line - Wikipedia

   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. [1] 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.

8. G.992.5 - Wikipedia

   en.wikipedia.org/wiki/G.992.5

   G.992.5 (also referred to as ADSL2+, G.dmt.bis+, and G.adslplus) [1] is an ITU-T standard for asymmetric digital subscriber line (ADSL) broadband Internet access. The standard has a maximum theoretical downstream sync speed of 24 megabits per second (Mbit/s). Utilizing G.992.5 Annex M upstream sync speeds of 3.3 Mbit/s can be achieved.

9. G.992.2 - Wikipedia

   en.wikipedia.org/wiki/G.992.2

   Most ADSL modems and DSLAM ports support it, but it is not a typical default configuration. The transmission speed of G.lite (G.992.2) is 1.5 Mbit/s downstream and 512 kbit/s upstream. [1] The G.lite specification was an accelerated ITU-T effort to drive interoperability among vendors and was facilitated by the Universal ADSL Working Group, or ...
