ATM IMA Applications on an L2VPN

ATM IMA Applications on an L2VPN

As show in Figure 2-3, after ATM services from the NodeA are converged at the E1 or T1 interface on PE1, ATM cells are encapsulated into PSN packets that can be transmitted over PSNs. After arriving at the downlink PE2, the PSN packets are decapsulated into the original ATM cells and then the ATM cells are sent to the 3G radio network controller (RNC).In this solution, services of multiple types are converged at a PE on a PSN. This improves the efficiency of current network resources, reduces Plesiochronous Digital Hierarchy (PDH) VLLs, and facilitates the deployment of new sites as well as the maintenance and management of multiple services.
