The Cisco ASR 9000 Series Mod80 Modular Line Cards are fully compatible with the Cisco ASR 9922, 9010, and 9006 systems, route switch processors (RSPs), and line cards. No hardware upgrade to the chassis or cooling system is required. Total bandwidth is dependent on the number and type of RSPs installed.The new line cards deliver the ability to mix and match modular port adapters so that customers can customize each slot in the Cisco ASR 9000 to their specific port demands. As an example, a 4-port 10-Gigabit Ethernet modular port adapter can be matched with a 20-port 1-Gigabit Ethernet modular port adapter, all in a single slot.
