Cisco Dedicated Token Ring Port Adapters

Cisco Systems has expanded and enhanced its Token Ring solution for Cisco 7200 and 7500 series routers with the introduction of the Dedicated Token Ring port adapter (PA-4R-DTR). The Dedicated Token Ring port adapter offers increased functionality, flexibility, and performance for Token Ring networks at a very attractive price per port. The new port adapter offers a broad range of connectivity options, from traditional 4- and 16-Mbps half-duplex Token Rings to direct attachment of high-speed, full-duplex devices such as servers and switches.
