Hi there, Community friends!This time, I will share with you a brief introduction about TDM PWE3. Hope you like!
The TDM PWE3 technology emulates the basic behaviors and characteristics of TDM services on a packet switched network (PSN) by using the PWE3 mechanism, so that the emulated TDM services can be transmitted on a PSN. TDM PWE3 services are also called CES services carried by PWE3.
TDM PWE3 aims to transmit TDM services over a PSN. Especially, the CESoPSN mode can compress idle timeslots to reduce the required transmission bandwidth.
Figure 1 shows the typical application of TDM PWE3. The native TDM services between the BTS and the BSC are transmitted over a PSN. PE1 emulates the native TDM services from the BTS into CES services by using the CESoPSN technology. Then, the CES services are transmitted to PE2 over the PSN. Finally, PE2 restores the CES services to the native TDM services for transmission to the BSC.

Aided by the TDM PWE3 technology, conventional TDM networks can be connected by a PSN. In this manner, PWE3 protects customer investment in TDM networks and constructs all-IP network architecture.
That's all, I welcome everyone to leave a message and exchange in the comment area!
