ADSL Modulation — ADSL Modulation refers to a frequency-division
◆
multiplexing (FDM) scheme utilized as a digital multi-carrier
modulation method for DSL. A large number of closely-spaced
orthogonal sub-carriers are used to carry data. The data is divided into
several parallel data streams or channels, one for each sub-carrier.
Each sub-carrier is modulated with a conventional modulation scheme
(such as G.lite, ADSL2, etc. or more commonly ADSL2+).
G.lite — A standard that defines the more economical splitterless
■
ADSL connection that transmits data at up to 1.5 Mbps downstream
and 512 Kbps upstream. This ADSL option can be installed without
an on-site visit by the service provider.
G.dmt — A standard that defines full-rate ADSL, and utilizes
■
Discrete Multi-Tone (DMT) signaling to transmit data at up to 8
Mbps downstream and 640 Kbps upstream.
T1.413 — ANSI standard that defines the requirements for ADSL
■
for the interface between the telecommunications network and the
customer installation in terms of their interaction and electrical
characteristics. (The Gateway complies with Issue 2 of this
standard.)
