What is ISDN?
5.A ISDN stands for Integrated Services Digital Networks. It is an all-digital, circut-switched telephony system that is an alternative to analog modems, although both can operate over regular copper telephone lines. What this means for you is faster, more reliable connections. ISDN comes in two different speeds, 64k and 128k. Many of the problems that exist with normal analog modems which operate over POTS (Plain Old Telephone System) do not exist with ISDN.
ISDN is a digital replacement for today’s dial-up phone system. Unlike the slow, often noisy, analog phone lines widely used today, ISDN’s entirely digital system allows for a variety of traffic (audio, video, data, etc), at speeds of up to 128 kbps (kilobits per second). ISDN has three communications channels, two of which are 64 kbps and can be combined for a total of 128 kbps. The third channel is used for administration and call control by the telephone company. ISDN requires special phone lines from the telephone company, and special hardware to operate the ISDN phone line. New Mexico Technet now offers ISDN Internet Access. Please see About ISDN for more information. If you have any questions regarding this or any of New Mexico Technet’s other services, please feel free to contact us at any time.
