Circuit switching is a type of communications in which a dedicated channel or circuit is established for the duration of a transmission, a method used by the traditional telephone call- calls carried over the public switched telephone network (PSTN), also referred to as the Plain Old Telephone Service (POTS). Packet switching uses different methods. Packet switching networks are connected through many routers, each serving different segment of networks. Circuit-switched networks are used for traditional phone calls and packet-switched networks handle data. But nowadays, you can get phone service delivered over the Internet just like digital data packets. In this video, you will find examples to demonstrate these two signaling methods.
