The benefit of circuit switching is that it has a specialized circuit without exchanging (guaranteed performance). Packet-Converting uses either TDM or FMD. TDM has the added benefit of being able to use most of the (multiplexing) bandwidth.
It is the most recognizable method used to create a communication over network is circuit switching.
It can be used for regular phone conversations.
This enables people to share devices and circuits for conversation.
Through network utilization, every user has an exclusive connection to a circuit.
