IIntegrated Services Digital Network, or ISDN, is a dial-up connection carried over specially installed lines, while digital subscriber line, or DSL, is an always-on connection that does not need to dial over the lines that it uses. ISDN and DSL work over the same kind of network, but the main difference is that the ISDN has to actually dial out to achieve a connection for data to flow through. DSL does not need to dial out, and as a result, the user can make calls while connected to the Internet.Continue Reading
The telephone wires that carry signals for both systems are copper-based wires. The lines for ISDN have to be installed because they require an adapter installed at both ends of the line. This means that the service provider must have the adapter, and it must also be placed into the home or business where the service is being used.
Generally, DSL uses existing telephone lines along with a modem. A DSL connection does not need any additional installation of wires as long as there is already a telephone line in the home. Most DSL connections are actually ADSL, with the "A" standing for asymmetric. ADSL is better suited to a home or business that downloads data more than it uploads it.Learn more about Internet & Networking

The primary differences between cable and DSL include price, speed and connection. DSL connections transmit digital data through a traditional telephone line, whereas cable connections transmit data through cable lines. DSL uses a modem and dials through the telephone line, whereas cable uses existing internal or external coaxial cables as well as fiber-optic cable. As of 2014, cable is also faster than DSL and more widely available.Full Answer >
DSL, short for digital subscriber line, is a broad term for a digital high-speed data connection that uses the same wiring as a regular telephone line. Asymmetric DSL, or ADSL, is a specific type of DSL connection that divides the frequencies used to transmit data, which provides significantly improved download speeds at the cost of slower upload speeds.Full Answer >
