l The working mode of the H802EDTB board is set to SAToP by running the board
workmode command.
l A static route or dynamic route is successfully configured on each device over the network
so that the IP routes between LSRs are reachable.
Context
The implementation process of TDM PWE3 is as follows:
1. The data of the Nx64k private line service or ISDN PRI PBX service is converged and then
transmitted to the H802EDTB board of the MA5600T/MA5603T/MA5608T.
2. After performing SAToP processing (adding CW control word and RTP header) on the E1
data, the H802EDTB board sends the data to the SPUB board through the control board.
3. After performing the PW and MPLS encapsulation on the packets, the SPUB board adds
the ETH header to the packets, and then sends them to the control board.
4. The control board performs Layer 2 forwarding and sends the packets to the upstream port.
5. The packets are sent over the PSN network to the peer PWE3 gateway (such as the PTN).
6. The PWE3 gateway restores the E1 signals from the packets and then sends them to the
DDN network or SDH network.
