ISDN, or Integrated Services Digital Network, is an advanced digital communication technology that enables the transmission of voice, video, and data over conventional telephone lines. This technology utilizes dedicated channels to carry information efficiently.
ISDN, short for Integrated Services Digital Network, is a set of communication standards that enable digital transmission of voice, data, video, and other services over traditional telephone lines. Developed in the 1980s, ISDN revolutionized how we connect and share information.
Integrated Services Digital Network (ISDN) is a set of communication standards for simultaneous digital transmission of voice, video, data, and other network services over the digitalised circuits of the public switched telephone network. [1] .
Note: ISDN is a circuit-switched telephone network system, but it also provides access to packet-switched networks that allow digital transmission of voice and data. This results in potentially better voice or data quality than an analog phone can provide.

ISDN, or Integrated Services Digital Network, is a communication technology that allows voice calls, video calls, and data to be sent digitally over regular telephone lines. In simple terms, ISDN is a system that upgrades old phone lines so they can do more than just voice calls.
ISDN, all-digital high-speed network provided by telephone carriers that allowed voice and data to be carried over existing telephone circuits. In the early 1980s ISDN was developed as an offshoot of efforts to upgrade the telephone network from analog to digital using fiber optics.
