Using DMT for theUniversal ADSL Service (G.Lite)

Provisions for the high-speed data rates of full ADSL are good, but not every consumer is looking for the high data rates afforded on ADSL. Therefore, the Universal ADSL Working Group decided to reevaluate the need for the end user.

They determined that many consumers need downloads of 1 to 1.5 Mbps and uploads of 160 to 640 Kbps. Consequently, ADSL-lite specification was designed with these speeds for the future.

Initially introduced in early 1998, the specification was ratified in late 1998 to facilitate the lower throughput needs of the average consumer. DMT is the preferred method of delivering G.lite service.

There is no way to know if the network providers can support hundreds of multi-megabit ADSL up- and download speeds on their existing infrastructure. However, using the G.lite specification can support low-demand users more efficiently.
