V.90

This configuration limits the transmissions to only a single D-to-A-to-D (digital-to-analog-to-digital) conversion process, which limits the amount of quantizing noise associated with the PCM encoding process.The V.90 standard was known as V.last, as it was expected to be the last conventional modem standard developed by the ITU-T.V.92 was developed shortly thereafter, in 2000. Note: Although V.90 modem technology is fully capable of achieving a downstream transmission rate of 64 kbps, the T-carrier systems in the North American PSTN use a bit-robbing convention that reduces the reliable maximum transmission rate to 56 kbps. Further, FCC limitations on amplitude levels restrict the downstream rate to 53.5 kbps in the United States.
