Chapter 2: ISDN Helps People Work Together

Some of the applications now made viable by ISDN are telecommuting, LAN-to-LAN and LAN-to-host interconnection, remote image retrieval, inexpensive video conferencing, workgroup collaborations, high-speed access to the Internet and other data sources, extended teleradiology and telemedicine, remote security and telemetry, accelerated links to distant libraries and research systems, and much, much more.

Through standard copper telephone lines, ISDN connections now replace the dialed analog connections of the past with the dialed digital connections of the future. The results of this simple fact are significant:

Expensive, dedicated digital lines are no longer the only way to achieve digital transmission speeds.

Modems to convert the digital pulses of computers to analog pulses for an analog network will become obsolete. Digital signals can now flow directly from one digital device (e.g., a PC or ISDN telephone ) to another through what is now an inexpensive yet fully digital connection.
