Creating a Four-Node Ring Using the Uplink Cards
This chapter provides information for creating a four-node ring, either DPT or IEEE 802.17 RPR, using
the DPT or RPR/SRP uplink cards.
DPT Uplink Card
Use
Create a four-node DPT ring by connecting the fiber-optic cables to DPT uplink cards that are installed
in routers on the network.

Node 4
The TX side B port on Node 1 goes to the RX side A port on the next router, which will become Node
2. The labels above the fiber connectors identify side A (left port) TX and RX, and side B (right port)
TX and RX. (See
