13.5. ISDN

Last modified by Bill Lloyd <wlloyd@mpd.ca>.

A good resource for information on ISDN technology and hardware is Dan Kegel's ISDN Page.

A quick simple roadmap to ISDN follows:

• If you live in Europe I suggest you investigate the ISDN card section.
• If you are planning to use ISDN primarily to connect to the Internet with an Internet Provider on a dialup non-dedicated basis, I suggest you look into Terminal Adapters. This will give you the most flexibility, with the fewest problems, if you change providers.
• If you are connecting two lans together, or connecting to the Internet with a dedicated ISDN connection, I suggest you consider the stand alone router/bridge option.

Cost is a significant factor in determining what solution you will choose. The following options are listed from least expensive to most expensive.

13.5.3. Standalone ISDN Bridges/Routers
