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 Figure 4-1and Table 4-1to help organize the cable connections for a four-node DPT ring.

Create a four-node DPT ring by connecting the fiber-optic cables to DPT uplink cards that are installed in routers on the network.
