SDSL or Symmetric Digital Subscriber Line technology is a relatively unknown
broadband technology used to provide high-speed Internet connectivity at a
reasonable cost. It is
used primarily by small and medium size enterprises (SMEs) to transmit and/or
receive large
volumes of data across the Internet at very high speeds. SDSL can
transfer data at speeds of up to 3 Mbps (megabits per second) in either
direction.
Unlike other high-speed Internet technologies, SDSL does not require a
sophisticated optical or coaxial cable network to provide broadband
Internet connectivity. Instead, SDSL leverages the standard twisted-pair
copper wires that are used by conventional land-line telephones. Consequently,
the cost of providing SDSL service is relatively inexpensive and service is
now available in many areas.
SDSL is well-suited to small and medium sized businesses and to consumers
who require high bandwidth but can't justify the cost of dedicated,
expensive leased lines or frame-relay services.
