Token Ring is a 4 Mbps or 16 Mbps LAN based on the IEEE 802.5 standard. While this is a logical ring topology, the
physical cabling is typically designed in a star through the use of a MAU (multi-station access unit). Original specifications called for 150 ohm shielded twisted pair. Today 100 ohm
unshielded twisted pair is commonly used. While category 3 cabling is acceptable for the 4 Mbps version and category 4 for the 16 Mbps version, the use of category 5 will support
emerging Token Ring applications (such as Demand Access) that are designed to operate using this technology. Application Diagram - Token Ring
