The circuit switching unit is the actual electronic circuit (physical line) maintained in the process of communication, which in fact constitutes the most basic part of the switching network, and several switching units can be connected according to a certain topology to form a variety of switching networks. After this electronic circuit is established, the user always occupies a fixed transmission bandwidth from the sending end to the receiving end.

The switching unit is the most basic part to complete the switching function.

Each telephone is connected to a switch, which uses a switching method to allow telephone users to communicate easily with each other. For more than 100 years, although the telephone exchange has been updated many times, the mode of exchange has always been the circuit switching unit. As the number of telephones increases, switches connected to each other are used to complete the exchange of the whole network. Note that this switch uses the circuit switching unit method, and later packet switching uses the same telecommunications network, but a different type of switch (of course, the protocol is different).
