Essay / Research Paper Abstract
5 pages in length.
Determining the differences between ADSL, HDSL and DSL Lite, in
order to choose which is best for which consumer, we must first
gain a simple understanding of the terms. At that time a more
informed decision can be made as to whether each system is
preferable for business or personal use, whether it is expensive
or reasonable, and other informed opinions for the consumers of
each service. Bibliography lists 3 sources.

ADSL, HDSL and DSL-Lite 11/2000 to Use This Paper Properly, Determining
the differences between ADSL, HDSL and DSL Lite, in order to choose which is best for which consumer, we must first gain a simple understanding of the terms. At
that time a more informed decision can be made as to whether each system is preferable for business or personal use, whether it is expensive or reasonable, and other informed
opinions for the consumers of each service. DSL (Digital Subscriber Line) is a digital technology for implementing high-bandwidth data communication over standard copper telephone wire. There are several variations
of DSL technology such as ADSL (Asymmetric DSL), HDSL (High Bit-Rate DSL), IDSL (ISDN like DSL), RADSL (Rate Adaptive DSL), and MSDSL (Multirate symmetric DSL) (Morrison 1997). Between fifteen percent
and twenty percent of the telephone local loops, which are lines from the telephone office telephone switch to the home or office, have devices called loading coils; this is in
lieu of repeaters, installed to increase distances the analog voice signal may travel. ISDN circuits do not work well with loading coils, while xDSL technologies can use these circuits
(Morrison 1997). Costs for changes to the Central Office Switch to use ISDN can exceed $500,000, and data still uses the voice network; xDSL circuits access DSL Access Mutiplexers
(DSLAM) which then shunts traffic to a data network before hitting the voice switch -- the DSLAM connect DSL lines with some combination of ATM, Frame Relay, or IP network
