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.
