The Cisco 10720 Internet Router provides network access using Ethernet and optional Dynamic Packet Transport (DPT), Packet over SONET (POS), or IEEE 802.17 RPR technology for optical connectivity. Each router is equipped with one uplink card located in the upper card slot. The OC-48 RPR/SRP, OC-48/STM-16c DPT, and POS/DPT uplink cards are equipped with dual OC-48c/STM-16c optical uplink network ports with an aggregate bandwidth of 5 Gbps. The console/auxiliary card provides console and serial (AUX) ports only.
Although the console/auxiliary card does not provide uplink capabilities, it is described here because it is installed the same as the DPT and POS/DPT uplink cards. You can use the Cisco 10720 Internet Router console/auxiliary card with either a 24-Port 10/100 Ethernet TX access card or a Combined 4-Port Gigabit Ethernet 8-Port 10/100 Ethernet TX access card to customize the Cisco 10720 Internet Router as an Ethernet-only router.
For DPT and POS/DPT uplink cards, the cable connector is LC fiber-optic connector. For the RPR/SRP uplink card, the fiber-optic cable connects to an LC connector in a small form-factor pluggable (SFP) optical connector. When connecting to DPT networks, the left port is the Spatial Reuse Protocol (SRP) side A, and the right port is side B. (See Figure 1-1.) When connecting to POS networks, there are two individual ports. Each port consists of transmit (TX) and receive (RX). (See Figure 1-2.) When connecting to DPT networks in Resilient Pack Rings (IEEE 802.17 RPR) mode, the left port is span West, and the right port is span East. When in the Spatial Reuse Protocol (SRP) mode, the left port is side A, and the right port is side B. (See Figure 1-3.)
For information and instructions on connecting the optical cables to the DPT uplink card or to the RPR/SRP uplink card and for setting up four-node rings, see "Overview and Specifications" and Chapter 4, "Creating a Four-Node Ring Using the Uplink Cards."
