What is DSL?
Digital Subscriber Line, or DSL, is a broadband technology that
transforms a normal telephone line into a high speed broadband
connection. Typical residential offerings usually have a maximum of
1.5 mbps (1.5 megabits per second), but special connections for home
and office can be obtained to go well above that.
What is xDSL?
xDSL is a generic term used to refer to the family of DSL
technologies. There are several different forms of DSL with
different capabilities suited to different markets.
What is HDSL?
High bit-rate DSL or HDSL is a symmetrical service that offers
speeds of up to 1.5Mbps. It is used mainly by businesses that
require a higher level of upstream speed, to perform applications
such as Web hosting and teleconferencing.
What is RADSL?
Rate-adaptive DSL or RADSL is a variation of ADSL where the modem
can adjust the speed of the connection depending on the length and
quality of the line.
What is SDSL?
Symmetric DSL or SDSL is a connection that is used mainly by
small businesses and provides users with equal upstream and
downstream speeds of up to 2.3Mbps. It does not allow a phone to be
used at the same time but is suited to situations where the user
needs to send and receive large amounts of data. For more
information about SDSL, visit
SDSL.ca .
What is VDSL?
VDSL can operate in symmetric or asymmetric mode, providing
speeds of between 6 mbps and 25 mbps over a short distance of up to
300 meters. VDSL is typically provided from a street cabinet which
is directly linked by fibre to a telephone exchange. VDSL is a very
expensive technology to deliver and is unlikely to be deployed on a
wide scale.
What is ADSL?
ADSL is the most widely used form of DSL today. Please refer to
the ADSL portion of our website for full details.
