¿µ¹®³»¿ë¿ä¾à 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.
