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. This makes it both faster and of higher quality than dial-up internet service.

ISDN is more flexible than PSTN because it can provide both voice and data services over the same line. This means that you can make a phone call while simultaneously using the internet or transferring data. However, PSTN can only provide voice services and requires a separate line for data services.

7 (SS7) is a set of telephony signaling protocols developed in the 1970s, which is used to set up and tear down telephone calls in most parts of the world-wide public switched telephone network (PSTN).

Dial-up is a technology used to connect to the internet using a standard telephone line. It works by dialing a specific phone number provided by an internet service provider (ISP) and establishing a connection through a modem.

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. These digital lines could be copper lines.

There are two types of ISDN networks — BRI (Basic Rate Interface) and PRI (Primary Rate Interface). The major difference between BRI and PRI is the level of service and reliability. To sum them up: BRI is the lower tier of service.
