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
Create a four-node IEEE 802.17 RPR mode 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 RPR mode 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 RPR
mode 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.
