The TX span East port on Node 1 goes to the RX span West port on the next router, which will become Node 2. The labels above the fiber connectors identify span West (left port) TX and RX, and span East (right port) TX and RX. (See Figure 4-1.)

Create a four-node IEEE 802.17 ring by connecting the fiber-optic cables to RPR/SRP uplink cards that are installed in routers on the network. To create a four-node IEEE 802.17 ring, perform the following steps:

Step 1 Install an RPR/SRP uplink card in a Cisco 10720 Internet Router on the network.

Step 2 Choose a router with an RPR/SRP uplink card to become Node 1 in the four-node IEEE 802.17 ring.

Step 3 Add nodes to the ring by connecting the receive (RX) and transmit (TX) cables. The RX port on one RPR/SRP uplink card must be connected to a TX port on the next RPR/SRP uplink card.
