Therefore, this method can be used for the optimal design of circuit-switchednetwork.
因此,这一方法非常适合于电路交换网的优化设计。

In addition, the transport layer allows IMS devices to make and receive calls to and from the PSTN network or other circuit-switched networks via the PSTN gateway.
In a circuit-switchednetwork when you use a circuit, you have the full circuit for the time that you are using the circuit without competition from other users.
