Optimizing Web Graphics
- [AD96]
- The ADSL Forum An association of competing companies that provides information and tutorials on Asymmetric Digital Subscriber Line (ADSL) and other DSL technologies. An ADSL circuit connects an ADSL modem on each end of a twisted-pair telephone line, creating three information channels -- a high speed downstream channel, a medium speed duplex channel, and a POTS (Plain Old Telephone Service) channel. Downstream speeds range from 1.5 to 52 Mbps (VDSL) or T1 to T3+ speeds over existing phone lines. DSL technologies have an advantage over cable modems in that they are not shared.
