What is xDSL?
7.A DSL stands for Digital Subscriber Line. The “x” in xDSL represents any of the variations of DSL such as ADSL, CDSL, RADSL, and HDSL. Each of these services is different, technically speaking, but they give you the same effect: speed. Assuming you are close enough to the phone company’s central office, DSL could be able to provide you with speeds of up to 6.1 megabits/second. However, keep in mind that this is just the theoretical top speed; it is unlikely you would experience speeds this high. DSL is expected to replace ISDN and compete with the cable modem.
