Southborough, Massachusetts-based Chipcom Corp has launched a new Token Ring bridge module for its ONline System Concentrator family of intelligent hubs. The product is claimed to integrate a two-port Token Ring-to-Token Ring bridge using one slot in either the six- or 17-slot concentrator. The product comes in a Source Routing version – for sites using exclusively Source Routing bridging – and a Source Routing/Transparent version for users of mixed SR and SRT networks. The rationale behind an exclusively SR version is to offer a lower cost product for SR-only users, while the company is also offering an upgrade option for users upgrading their networks to a mixed SR and SRT environment. The module assigns one port to the front panel for shielded or unshielded twisted pair connection, while the other port connects to the concentrator’s backplane to allow users to connect and switch between any of seven internal ONline Token Ring networks. Both ports operate at 4Mbps or 16Mbps, and the company says that the module has management options for both IBM-only and SNMP environments. It also says that the module is upgradable by downloading software to its Flash PROM memory. The SR version – Model 5202B-TT-SR – has a US list price of $5,500, while the 5202B-TT-SRT costs $6,900. Both are due to ship in 60 days; no word on European pricing.
