The network in which users who are calling and being called first establish a dedicated channel (or circuit) between them.
The network in which users who are calling and being called first establish a dedicated channel (or circuit) between them. The channel is also only accessible to users while the connection is live. Since it allows for the availability of links, wires, or frequencies between system users for each call, the telephone system serves as the standard illustration of a circuit switched network. Two channels are designated for full-duplex communication while one channel is set up for half-duplex communication. The circuit switching network is primarily responsible for handling voice communication, which calls for real-time services with little to no delay. The only time the network requires a call setup delay is before a conversation. Due to network congestion or overload, calls may be blocked or dropped.
