V.91: A digital modem operating at data signalling rates of up to 64 000 bit/s for use on a 4-wire circuit switched connection and on leased point-to-point 4-wire digital circuits, published in 1999 V.92 is an ITU-T recommendation, titled Enhancements to Recommendation V.90 , that establishes a modem standard allowing 56 kbit/s download, 48 ...
The 201A Data-Phone was a synchronous modem using two-bit-per-symbol phase-shift keying (PSK) encoding, achieving 2,000 bit/s half-duplex over normal phone lines. [10] In this system the two tones for any one side of the connection are sent at similar frequencies as in the 300 bit/s systems, but slightly out of phase.
V.92 is an ITU-T recommendation, titled Enhancements to Recommendation V.90, that establishes a modem standard allowing near 56 kb/s download and 48 kb/s upload rates. With V.92 PCM is used for both the upstream and downstream connections; previously 56K modems only used PCM for downstream data.
The SupraFAXModem 14400 is a v.32bis modem. When it was launched by Supra, Inc. in January 1992 for US$399 (equivalent to $870 in 2023), [N 1] the 14,400 bit/s model was less expensive than most existing 9600 bit/s models. This price/performance ratio made it a disruptive technology, and its introduction drove modem prices sharply downward ...
Using DMT is useful since it allows the communications equipment (user modem/router and exchange/DSLAM) to select only bins which are usable on the line thus effectively obtaining the best overall bit rate from the line at any given moment in time. With COFDM, a combined signal containing many frequencies (for each bin) is transmitted down the ...

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 ...
