Cisco PA-T3/E3-EC

The Cisco 1-Port Clear Channel Enhanced Capability Port Adapter for the Cisco 7200 Series, Cisco 7301, and Cisco 7201 Routers are enhanced "two-in-one" versions of the earlier Clear Channel T3 and E3 port adapter. This new product assists network implementers by minimizing sparing of both T3 port adapters for the United States and E3 for European and Asian implementations. They provide a new software architecture that allows selecting either T3 or E3 by way of software configuration coupled with a more powerful chipset that lowers CPU usage. The new port adapters lower CPU use by more than 15 percent.
