Structure-aware TDM Circuit Emulation Service over Packet-Switched Network (CESoPSN)
Structure-Aware Time Division Multiplexed (TDM) Circuit Emulation Service over Packet Switched Network (CESoPSN) is a method of en-capsulating TDM signals into CESoPSN packets, and in the reverse direction, decapsulating CESoPSN packets back into TDM signals also, referred to as Interworking Function (IWF).
