<div><p>Digital subscriber line (DSL) refers to a class of technology used
|
|
to obtain more bandwidth over existing copper telephone cabling running between
|
|
a customer's premises and an ISP provider.</p>
|
|
<div class="section"><p>DSL allows simultaneous voice and high-speed data services over
|
|
a single pair of copper telephone wires. Modem speeds have gradually increased
|
|
through the use of various compression and other techniques, but at today's
|
|
fastest (56 kbit/s) they are approaching the theoretical limit for this technology.
|
|
DSL technology enables much higher speeds across the twisted pair lines from
|
|
the Central Office to the home, school, or business. Speeds up
|
|
to 2 Megabits per second are achievable in some areas. PPPoE stands for Point
|
|
to Point Protocol over Ethernet. PPP is typically used over serial communications
|
|
like dial-up modem connections. Many DSL Internet service providers now use
|
|
PPP over Ethernet because of its added login and security features. What is
|
|
a DSL modem? A DSL "modem" is a device that is placed at either end of the
|
|
copper telephone line to allow a computer (or LAN) to be connected to the
|
|
Internet through a DSL connection. Unlike a dial-up connection, it typically
|
|
does not require a dedicated telephone line (a POTS splitter box enables the
|
|
line to be shared simultaneously). Although DSL modems resemble conventional
|
|
analog modems they provide much higher throughput.</p>
