SuperStack II Hub TR hubs (here in the 24-port model) combine RMON-based management with the most advanced physical layer support in an affordable, expandable platform for mission-critical Token Ring networks. The hubs provide advanced error recovery and fault isolation technology, jitter cancellation and retiming mechanisms, and sophisticated SNMP RMON network management.

The SuperStack II Hub TR is part of 3Com's SuperStack system, an innovative architecture that allows stackable hubs, bridges, routers, switches, and SNA-to-LAN conversion devices to be easily integrated and managed as one system. SuperStack II Hub TR hubs provide robust, scalable 4/16 Mbps Token Ring connectivity for stand-alone workgroups and floor-distribution LAN configurations. Both models offer slide-in modules for supporting fiber, unshielded twisted-pair (UTP), and shielded twisted-pair (STP) wiring using fiber and/or copper RI/RO (Ring-In/Ring-Out) expansion modules. In addition, Simple Network Management Protocol (SNMP) RMON-based management is available at any time with a slide-in SuperStack II Hub TR RMON Management Agent Module or Advanced RMON Management Agent Module. For connectivity in a central wiring closet, cascade cables can connect up to 20 hubs in one rack, or up to 260 users. Three different cascade cables are available: a 12-inch Expansion for ring expansion in the same wiring closet or stack, a 4-foot Cascade Cable and an 8-foot Redundant Ring Cascade Cable for redundant connections within the same stack. The redundant cable directly connects the top hub to the bottom hub in a stack, providing a backup path should one of the expansion cables or hubs fail. Slide-in RI/RO expansion modules also allow main ring connections to 20 hubs in different locations from each other. Slide-in RI/RO expansion modules are available in fiber, copper, and copper/fiber, providing flexibility depending on your wiring configuration requirements. And for connectivity between 3Com CoreBuilder 2500/6000, ONline, ONsemble and SuperStack II Hub TR hubs, slide-in copper or fiber ONtrunk modules are available for seamless integration. The stackable architecture of the SuperStack II Hub TR hubs make them ideal for dynamic LAN environments that require fast and easy reconfiguration. SuperStack II Hub TR hubs support all the industry-leading reliability features, including Phase-Locked Loop retiming, Zero Delay Lockout, and Distributed Recovery Intelligence.
