Data Transfer Rates
ANSI T1.413 / ITU G.992.1 Data Rates
Data rates for DMT mode are partitioned at 32 kb/s increments for both the upstream and
downstream data rates adhering to the DMT Standards. The downstream data rates extend
from 32 kb/s to 8.064 Mb/s. The upstream data rates extend from 32 kb/s to 1024 kb/s.

ITU G.992.2 Data Rates
Data rates for G.992.2 (G.lite) mode are likewise partitioned at 32kb/s increments. The
downstream data rates extend from 64 kb/s to 4 Mb/s. The upstream data rates extend from
32 kb/s to 1024 kb/s.
