For the PWE3 service model and network application, see Configuring the PWE3 Private Line
Service.
PWE3 encapsulation may be performed in the following typical scenarios based on user-side
service types and upstream network types.

4.3.1 Example: Configuring ATM PWE3 to Implement Migration
from ATM Network to IP Network
ATM PWE3 applies to ATM network reconstruction. If the IP protocol is used in the transport
network, ATM PWE3 is recommended to migrate the ATM network to an IP network.

The original ATM DSLAM is replaced by the MA5600T/MA5603T/MA5608T and the
upper-layer ATM BRAS remains.
ATM service data is transparently transmitted across the network.
The quality of service (QoS) such as traffic and priority, can be guaranteed for real-time
ATM services.

Application
Mainly used for the ATM network reconstruction. When
the IP protocol is deployed for the transmission network
and the ATM network evolves to the IP network, PWE3
encapsulation is recommended.
Mainly used for the ATM network reconstruction. When
the MPLS protocol is deployed for the transmission
network and the ATM network evolves to the IP network,
PWE3 encapsulation is recommended.
Mainly used for private network data interaction between
different enterprise branches.
Mainly used to integrate the TDM circuit into the packet
switched network (PSN) to provide more value-added
services. When the IP protocol is deployed for the
transmission network and the IP network provides
simulated TDM services, PWE3 encapsulation is
recommended.
