By utilizing ISDN, users can access the internet, video conferencing, and other advanced features at speeds up to 128Kbps (kilobits per second). Additionally, ISDN offers some advantages over traditional analog networks, including better security, higher reliability, and easier installation. With these benefits, it’s no wonder why ISDN is becoming increasingly popular for businesses and individuals alike.

Disadvantages of ISDN
ISDN, or Integrated Services Digital Network, is an older technology that is being phased out by many service providers. Despite its age, ISDN can still be useful in certain applications and scenarios. That said, there are a few major disadvantages to ISDN that should be noted before considering it as an option. ISDN requires dedicated lines and dedicated equipment, which can be expensive to install and maintain. Additionally, since ISDN is an older technology, it lacks the capacity for some of the more advanced services offered by newer technologies such as VoIP. Finally, ISDN is limited in terms of bandwidth and speed, so it is not ideal for applications that require a lot of data or high speeds.
