Chapter 4 Creating a Four-Node Ring Using the Uplink Cards

DPT Uplink Card

Step 1 Install a DPT uplink card in a Cisco 10720 Internet Router on the network.

Step 2 Choose a router with a DPT uplink card to become Node 1 in the four-node DPT ring.

Step 3 Add nodes to the ring by connecting the receive (RX) and transmit (TX) cables. The RX port on one DPT

uplink card must be connected to a TX port on the next DPT uplink card.

Figure 4-2 provides a view of the network when a four-node DPT ring is created.
