An Integrated Switched Digital Network (ISDN) is a telecommunications technology that allows for the simultaneous transmission of voice, data, and video over digital lines. It integrates various forms of communication through a single network, providing higher quality and more reliable connections compared to traditional analog systems. ISDN is commonly used for telephone services, video conferencing, and high-speed internet access. It features two main types of services: BRI (Basic Rate Interface) for smaller users and PRI (Primary Rate Interface) for larger organizations.

It means that the network card is embedded into the device. In other words, it is not removable.
Devices used to prepare digital data for transmission over the public switched telephone network (PSTN) include modems, which modulate digital signals into analog for transmission and demodulate incoming analog signals back into digital form. Additionally, routers may be employed to manage data traffic and ensure efficient routing over the network. Digital signal processors (DSPs) can also be utilized to optimize signal quality and reduce noise during transmission.
The first circuit-switched network was the telephone system.

Cellular Telephones is using the Integrated Services Digital Network ISDN while the Cordless Telephone is using the Public Switched Telephone Network PSTN, same with ordinary telephone.
Is a piece of circuit - switched network equipment used in telecommunications network.
The Internet is packet switched, meaning each individual packet is routed from the source to the destination separately, and possibly through different paths. An example of a circuit-switched network would be the telephone network, where a connection from one end to the other is created and maintained until the call is disconnected.
