Frequently Asked Questions (FAQs)
What is Digital Subscriber Line (DSL) service?
DSL is an innovative technology that turns your existing phone line into a multi-channel data-delivery system. One channel transmits voice services exclusively, so you can surf the Web while talking (or faxing) on the same phone line at the same time. The second channel transmits data downstream at high speeds, and a third channel transmits data upstream.
There are so called "modems" at each end of the phone line. One is connected to your computer; one is located at the telephone company's Central Office (CO) connection point. Working together, they provide a dedicated connection that avoids the need to dial up for access like with traditional analog modem Internet access.
DSL modems aren't really
modems, are they?
DSL equipment is a network termination device with a micro-router inside. It doesn't make calls the way a traditional modem does, nor can it be used to place calls to a traditional modem. The DSL micro-router is used to connect only to another DSL device. That device carries traffic back to us and, from there, out onto the Internet.
