What is DSL?
DSL, or Digital Subscriber Line, is an internet connection that enters your home or business on a phone line.
ADSL rides an existing voice line, meaning that once an order is complete, an ADSL modem is installed on a working phone jack, and you are online. Because the data and voice use different frequencies, the ADSL can be connected to Visionary at all times, and your phone can be used at any time as well.
SDSL/SHDSL travels its own phone line that is installed before the order is complete. It does not share the phone line with voice. The phone line is included with the price of the SDSL/SHDSL product.
