The telecommunications industry is evolving rapidly. Dynamic changes are taking place, and many old technologies are being replaced with emerging ones. One such radical development is the shutdown of ISDN. Now, you may not be very familiar with the term, and even wonder what is meant by it- let us understand it a bit more closely.

ISDN is an acronym for Integrated Service Digital Network. It is a circuit-switched telecommunication channel that enables users to send voice and data signals over digital lines at the same time. It was launched in the year 1986 as and innovation to replace the obsolete landline technology.

Business organizations were extremely excited about ISDN technology at that time as it both an analog phone line, as well as support video conferencing facilities. In fact, at that particular time, ISDN offered the highest speed of the internet (128 kbps). This meant that data could be sent easily, without any line disturbances, or audio distortion.

However, with the passage of time, ISDN technology is now considered outdated.
