<P> Cisco Systems is expanding and enhancing its Token Ring solution for Cisco 7200 Series routers with a Versatile Interface Processor with the new full duplex Token Ring port (PA-4R-FDX) port adapter. The new PA-4R-FDX protects your router investment while enabling migration to full duplex operation as your performance requirements increase. The PA-4R-FDX port adapter supports four Token Ring interfaces for a Cisco 720X or VIP2-based 7XXX router. Each Token Ring interface can be configured for 4 Mbps or 16 Mbps in half duplex or full duplex operation. The PA-4R-FDX can be installed in Versatile Interface Processor port adapter slots in a 7000 series router, or in any port adapter slot in the Cisco 7200 series routers. With all this and more, the PA-4R-FDX is the best choice for your networking solutions. </P>
