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.

The FlexPoint TR is a fully compliant IEEE 802.5j 4 or 16 Mbps Token Ring copper to fiber converter. It auto-senses and self-configures to the ring speed. The FlexPoint TR features an intelligent attachment auto-sensing circuit. It identifies the type of device attached to its UTP connector and self-configures accordingly.The UTP port of the FlexPoint TR may attach to a workstation's network interface card (NIC) or to a concentrator's ring-in, ring-out or lobe. The FlexPoint TR can attach a workstation via fiber to a concentrator lobe, extend ring-in and ring-out via fiber between concentrators and extend a lobe to a full concentrator using Omnitron's Lobe Extension Technology. For smart auto-sensing Token Ring switches, the FlexPoint TR supports server or workstation fiber attachment and fiber ring extension. The FlexPoint TR supports category 3 wiring or higher, with category 5 recommended for top performance. Using category 5 wiring, the FlexPoint TR reaches distances of up to 150 m at 16 Mbps and 500 m at 4 Mbps. On the fiber port, it reaches distances of up to 2.5 km using multimode fiber and up to 20 km using single-mode fiber. The FlexPoint TR provides media status and insertion progress indications for the copper and fiber ports. Smart LED indicators display insertion status and report problems. The FlexPoint TR features a media test that checks the attached copper and fiber cables for integrity and reports any detected defects. The FlexPoint offers several mounting options. The converter can be mounted stand-alone utilizing optional wall-mounting hardware. It can also be rack-mounted using a 5-unit shelf or in a high-density, 14-unit, dual power-redundant Powered Chassis.

Description:

Catalyst 5000 family switches support both 4- and 16-Mbps Token Ring networks. This fiber Token Ring module (WS-X5031) has 16 Volition VF-45 socket connectors for Token Ring connections. The 16 ports on the fiber Token Ring module support 62.5 micron multimode fixed fiber connections through ST to Volition VF-45 or SC to Volition VF-45 patch cords.The ports on the Catalyst 5000 family fiber Token Ring module allow you to attach the module to a traditional main ring path coming from either a multistation access unit (MSAU) or a controlled access unit (CAU). You can configure any of the 16 ports to connect to the ring in/out ports of a MSAU or CAU. The module has a loopback function that ensures that there is no break in the attached main ring, even if a port is disabled or the switch is powered off. When you attach a cable from the RI port of a MSAU port to one of the two switch ports, you join the primary and backup in a MAU/CAU main ring system. Connecting the other end of the main ring to the other switch port creates redundant paths because the two switch ports are connected to the same segment.
