It is retained for the value of any residual information contained in it. family of standardsHDSL, SDSL, ADSL, VDSL comprise the main DSL standards. Strictly speaking, the acronym DSL is actually an early low speed standard, and the 4 letter DSL acronyms are the standards in use today, but DSL has become a blanket term for all these technologies. Recently, the internation standards union settled on one consumer standard for DSL, called G.lite, also known as ADSL lite.
ADSLThe A in ADSL means asymmetric DSL. This recognizes that for home use, since people tend to be more of a consumer of data than a producer, a slower upstream (upload) speed can traded off for a faster downstream (download) speed. In addition, the ADSL standard allows for regular phone service to be squeezed into the low end of the frequency spectrum. ADSL therefore needs a splitter to be placed during installation.
