Key Concepts

Integrated Services Digital Network (ISDN)

ISDN, or Integrated Services Digital Network, is a digital networking technology that transmits voice and data over traditional telephone networks. It is designed to provide faster and higher-quality communication compared to analog dial-up, while still utilizing the telephone system’s infrastructure for connection.

Dial-up Access

Dial-up access is a method of connecting to a network or the internet using a telephone line and a modem. It requires the telephone system’s infrastructure to place a connection call, making use of the Public Switched Telephone Network to transmit data over analog signals.

Public Switched Telephone Network (PSTN)

The Public Switched Telephone Network (PSTN) is the traditional circuit-switched network for telephone communications. It is integral to dial-up access because it provides the physical and signaling network that enables modems to connect through dialing a phone number to establish a remote connection.
