1. How Circuit-Switched Digital Networks Work About Circuit switching ISDN TCP/IP Dial-Up

2. About Circuit switching In the data communication, the method communicated with the line secured while communicating for a long time is called circuit switching.

3. ISDN The ISDN stands for Integrated Services Digital Network.This is a digital line network can be used for circuit switched packet data communications. In this case, switch, relay circuit, which is digital subscriber line before.
