Board Configuration Information
For the EPLAN (IEEE 802.1d bridge) services supported by Ethernet switching boards, refer to
Table
In this example, the convergence node NE1 is configured with an EFS8 board that supports the
IEEE 802.1d bridge to implement EPLAN services wherein user VLANs are not limited.
The access nodes NE2 and NE4 each are configured with an EGT1 board. The EPL services are
configured to be transparently transmitted from NE2 and NE4 to NE1.
4.8.2 Signal Flow and Timeslot Allocation
The Ethernet services of the convergence node are received from an external port, forwarded to
an internal port through Layer 2 switching, encapsulated, and transparently transmitted on the
SDH network. In this way, the node communicates with a remote node.
