16 Mb/s token ring on unshielded twisted pair cabling

Abstract

Local area networks operating on structured cabling systems using unshielded twisted pair (UTP) cable are finding increased utilization. These systems provide low cost installation and easy administration. The paper addresses the technical issues concerning the implementation of a robust and practical 16 Mb/s token ring LAN using unshielded twisted pair cabling for lobe connections. Three technical approaches are presented and evaluated for both common unshielded twisted pair cable and new high performance unshielded twisted pair cable. It is shown that 16 Mb/s token ring can operate with lobe lengths of 300 feet on both types of UTP cables provided the appropriate technical approach is implemented.<>
