What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in a circuit-switched network?

Full Problem is:

What advantage does a circuit-switched network have over a packet-switched network?
What advantages does TDM have over FDM in a circuit-switched network?

Solution is:

A circuit-switched network can guarantee a certain amount of end-to-end bandwidth for the duration of a call.
But in most packet-switched networks today (including the Internet) cannot make any end-to-end guarantees for bandwidth.

This is the main advantage of circuit-switched network over a packet switched network.

FDM requires sophisticated analog hardware to shift signal into appropriate frequency bands but TDM doesn't require that sophisticated analog hardware to shift signal.
