Cisco 1 Port T3/E3 Spare

The Cisco 1- and 2-Port Enhanced Capability Clear Channel Port Adapters for the Cisco 7200 Series Routers (Cisco 7201 and 7301 Routers) are enhanced two-in-one versions (part numbers PA-T3/E3-EC and PA-2T3/E3-EC) of the earlier Clear Channel T3 and E3 port adapters (part numbers PA- T3+, PA-2T3+, PA-E3, and PA-2E3). These new products assist 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 usage by more than 15 percent.

These new port adapters can perform at line-rate performance with lower CPU usage on the Cisco 7200 Series and Cisco 7201 and Cisco 7301 platforms while providing scalable trunking services.
