ISDN stands for Integrated Services Digital Network. To you that means Incredibly Speedy Data Now and high speed Internet access. ISDN is a high speed, high capacity, high quality form of voice, data and video communication. The ISDN Frequently Asked Questions page answers many common queries about ISDN. ISDN is a telephone line that provides two primary channels for communication. These channels allow you to connect more than one device to the line, such as a PC, a phone and a fax. You can then perform two tasks simultaneously, such as placing a call and sending a fax, or transmitting a data file and receiving a call. You can also combine the two (64k-speed) channels in to a single (128K-speed) channel and achieve ISDN's top speed for sharing data files and Internet access.

Some of the features and benefits of ISDN are listed here.

Higher Speed
ISDN allows you to send and receive data four times faster than traditional phone lines and modems.

Higher capacity
Higher capacity ISDN has two channels, or paths, for communication. These channels can be combined to send extremely large or data-intensive files, such as pictures, graphs, audio or even video! By combining both channels, high-speed Internet access can also be achieved.

Higher quality sound & data
ISDN is digital. Digital means fewer errors when sending or receiving files. Digital also means that voice and sound are crystal-clear. There is no noise or static on a digital line.

Higher feature functionality
An ISDN line can be configured with many of the features or services that you currently use with your traditional phone service such as Call Forwarding and Three Way Calling. ISDN is also available with some features such as CallerID, Call Waiting, and Call Hold.

Higher productivity
Because ISDN has two communication paths you can perform two communication tasks simultaneously. For example, you can send a data file and receive a phone call at the same time without the phone call disrupting the data transmission. This capability makes you more productive, which could save you time and money. Internet access is also accelerated, making you sessions more productive and enjoyable.

More cost-effective
For many BellSouth customers, ISDN is the most cost effective and efficient telecommunications service available.
