Also known as ITU G.992.5 Annex M, the standard extends the capability of basic ADSL2 by doubling the number of upstream
bits. Data rates can be as high as 24 Mbit/s downstream and 3.5 Mbit/s upstream depending on the distance from the DSLAM to
the customer premises. The main difference between this and ITU G.992.5 (ADSL2+) specification is that the
upstream/downstream frequency split has been shifted from 138kHz up to 276kHz, allowing upstream bandwidth to be increased
from 1 Mbit/s to 3.5 Mbit/s, with a corresponding decrease in downstream bandwidth.
