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.
