Nortel Centillion 20

Nortel Centillion 20 ... 24-Port Workgroup Switch is designed for deployment in the wiring closet and workgroup environments, and is the latest addition to the Centillion family of Token Ring switching solutions from Bay Networks, a Nortel Networks Business. The switch provides 24 RJ-45 ports for 4/16/32 Mbps Dedicated Token Ring (DTR) connectivity, and supports insertion of an optional unshielded twisted pair (UTP) or multimode fiber optic asynchronous transfer mode (ATM) expansion module. For maximum performance, each end user or network device can be directly connected to the switch, supplying each node with access to 4/16/32 Mbps of dedicated bandwidth. In existing local area networks (LANs) with multiple 4/16 Mbps hubs, each hub can be connected directly to the Centillion 20 switch, significantly increasing available bandwidth and removing data bottlenecks in busy workgroups. The Centillion 20 switch delivers a quick, cost-effective solution for upgrading shared Token Ring environments.
