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
individual ports. Each port consists of transmit (TX) and receive (RX). (See
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
