Again, you can use each channel separately or combine them for high-speed transfer of large files. Whether you access the corporate LAN in the evenings or maintain a full-time, remote home office, ISDN is the next best thing to being there. And in many markets, it's actually cheaper than an isolated analog business line. But ISDN delivers even more than that.

In simple terms, ISDN is a replacement for plain old telephone service, which was never designed to meet the needs of the information age. ISDN uses the same wiring that currently serves homes and businesses.
