This Recommendation specifies only discrete multi-tone (DMT) modulation and
incorporates components from ITU-T Rec. G.993.1 (VDSL), ITU-T Rec. G.992.3 (ADSL2), and ITU-T Rec. G.992.5 (ADSL2 plus) This Recommendation should operate reliably over loop lengths that are similar to those of ITU-T Rec. G.993.1, or slightly longer lengths due to the mandatory support of trellis coding. This Recommendation defines a wide range of settings for various parameters (such as bandwidth and transmitter power) that could potentially be supported by a transceiver. Therefore, this Recommendation specifies profiles to allow transceivers to support a subset of the allowed settings and still be compliant with the Recommendation. |
