Introduction to ADSL

• Why we chose this project
• Areas of focus-advantages, disadvantages and
  technological specifications.

ADSL

• What is ADSL, and why invest in it ?
• ADSL is the intern technology for the forty
  years.
• It uses the 750m existing copper wire lines. Thus
  making it cost effective when compared to fiber
  optics
• With ADSL you are always on-line, 24 hours a day

ADSL

• It operates at two different frequencies over the
  copper wires.One for upstream 75kHz, downstream
  900kHz.
• Thus leveraging the existing pressure on the POTS
  which operates at 4kHz

4
ADSL

• It supercharges copper wire. ADSL offers speeds
  of up to 9Mbps depending on how close it is to
  the central office
• It will offer many new applications such as
• Video Conferencing
• Distant Learning
• Video On Demand
