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] .

2024年8月6日 · The Integrated Services Digital Network (ISDN) is a set of communication protocols that enable the simultaneous digital transmission of voice, video, data, and other network services over traditional Public Switched Telephone Network(PSTN) connections.

ISDN or Integrated Services Digital Network, is a circuit-switched telephone network system that transmits both data and voice over a digital line. You can also think of it as a set of communication standards to transmit data, voice, and signaling.

2022年12月8日 · ISDN is defined as a set of standards and techniques in telecommunication that enables the digital transmission of data, voice, video, and other services simultaneously across a public telephone network.

2024年12月17日 · The Integrated Services Digital Network (ISDN) is a circuit-switched telephone network that combines voice and data transmission over a digital line. Consider it to be a set of standards...

2023年10月11日 · ISDN is a circuit-switched telephone network system, but it also allows access to packet-switched networks. ISDN is also used with specific protocols, such as Q.931, where it acts as the network, data link and physical layers in the OSI model.

2016年5月14日 · Stands for "Integrated Services Digital Network." ISDN is a telecommunications technology that enables the transmission of digital data over standard phone lines. It can be used for voice calls as well as data transfers.

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.

ISDN, or Integrated Services Digital Network, is a set of communication standards designed to facilitate the simultaneous digital transmission of voice, video, data, and other network services over the traditional circuits of the public switched telephone network (PSTN).

ISDN internet service is basically a telephone-based network system that operates by a circuit switch, or dedicated line. It can transmit data and phone conversations digitally over normal telephone wires.
