TDM and FDM are multiple access techniques used for multiplexing number of signals into a single single for bandwidth saving.
FDM is older technique of multiplexing whereas TDM is relatively a newer technique of multiplexing.
TDM advantage over FDM is that it offers bandwidth saving and there is low interference between the signals that are being multiplexed.
Telephones can able to communicate with other telephones through Public Switched Telephone Network, which transmit voice signal over circuit switching technology.

An SVC is an on-demand connection that is dynamically established by end devices through the Network-Network Interface (NNI) signaling method. There must be an ATM switch between the end-devices that dynamically route the call through the ATM cloud A PVC is a circuit that a network operator over an ATM-switched network between a specific source and a specific destination manually provisions
