ODULATION

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.
