1.1 About ADSL
Asymmetric Digital Subscriber Line (ADSL) technology provides
high-speed data access across regular phone lines (copper wires) by
making use of previously unused frequency bandwidth above the
voice band. By placing the ADSL signal above the frequency of the
voice signal, ADSL service is able to coexist on the same line with
your telephone service. ADSL is asymmetric in the sense that it pro-
vides a higher data rate in the downstream (receive) direction than
in the upstream (transmit) direction. Asymmetric operation is ideal
for typical home and small office use where files and information are
downloaded more frequently than uploaded.
corega DSLAAU is capable of supporting the following DSL stand-
ards: ANSI T1.413 Issue 2, ITU G.992.1 (G.DMT), ITU G.992.2 (G.lite), and
ITU G.992 Annexes A, B, and C as applicable.
