FAQ

What is ISDN?

ISDN is an abbreviation for Integrated Services Digital Network. ISDN transfers information digitally and integrated all telecommunication services (such as telephone, teletext, videotext, etc.) into a single network. Using ISDN, you can transfer text, voice, data files, and images. ISDN is ideal for teleconferencing applications.

Before the use of ISDN, Telecommunications operated using analog devices, which limited the quality of telecommunication transfers.

With ISDN technology, the telephone lines can transmit data digitally with much greater speed and clarity of transmission than with analog transmissions.

The ISDN is capable of transmitting all kinds of information at greatly accelerated rates. A typical modem transmission has a rate of 9.6Kbps (kilobits per second or thousand bits per second) to 56Kbps. ISDN digital technology allows transfer rates of up to 128Kbps.
