DSL and ISDN
Although the standard equipment provided by telephone company limits the amount of data you can transmit and receive over a voiceband modem, the copper wire that runs from your wall jacks to the switching station actually has a fair amount of capacity. DSL and ISDN take advantage of this capacity to offer high-speed digital communication links for voice and data.
DSL (Digital Subscriber Line) is a high-speed, digital, always-on Internet access technology that runs over standard phone lines. It is one of the fastest Internet connections that are affordable to individual consumers. Several variations of this technology exist, including ADSL (asymmetric DSL, with downstream speed faster than upstream speed). DSL is digital, so data doesn’t need to be changed into analog form and then back to digital as it does when you use a dial-up connection.
A DSL connection can simultaneously carry voice and data, if permitted by your DSL provider. The digital data and analog voice signals travel over DSL line to the local switching station. There the voice signals are transferred to the telephone company’s
The speed of a DSL connection varies according to the characteristics of your telephone line, the equipment at your local switch and your distance from the switching station.
ISDN (Integrated Services Digital Network) connections move data at speed that is not as fast as DSL or cable Internet service. As with DSL, ISDN is an all-digital service with the potential to simultaneously carry voice and data. A device called ISDN terminal adapter connects a computer to a telephone wall jack and translates the computer’s digital signals into signals that can travel over the ISDN connection. ISDN service is typically regarded as a high-speed Internet connection option for businesses that maintain small LANs.
