How do psuedo emulation wires work ? I know they are used to send TDM traffic over packet switching network. But how does MPLS achieve the transmission of SDH over PSN ? How do they emulate SDH services ?

Dear friend!

PWE3 is a Layer 2 service bearer technology that emulates the basic behaviors and characteristics of services such as ATM/IMA, Ethernet, and TDM on a packet switched network (PSN).Aided by the PWE3 technology, conventional networks can be connected by a PSN. Therefore, resource sharing and network scaling can be achieved.

As shown in figure, the PE device uses CESoPSN to emulate native TDM services. SAToP uses a similar encapsulation process, but does not identify the E1 frame format or process the timeslots of the E1 frame.
