Product Description
The 3Com 3C359B is a network interface card (NIC) designed to connect computers to a Token Ring Local Area Network (LAN) operating at speeds of 16 Mbps. Unlike Ethernet, Token Ring uses a token-passing mechanism to control access to the network medium, providing deterministic performance characteristics. This card features a PCI bus interface, making it compatible with a wide range of computer systems that were prevalent during the peak of Token Ring technology adoption. The card is equipped with an RJ-45 connector, indicating its support for twisted-pair cabling, specifically for 10Base-T or 100Base-TX Ethernet standards, but it operates within the Token Ring protocol framework. This might seem contradictory, but many Token Ring implementations used RJ-45 connectors with specific cabling standards to interface with Token Ring hubs or MAUs (Multistation Access Units). It also supports auto-negotiation for both 4 Mbps and 16 Mbps Token Ring speeds, allowing it to adapt to different network configurations. While Token Ring networks have largely been superseded by Ethernet, the 3Com 3C359B was a crucial component for organizations that relied on this technology for its reliability and predictable performance. It provided a robust connection to the Token Ring infrastructure, enabling data communication for workstations and servers within those networks. Drivers for various operating systems of the time would have been available to ensure compatibility and functionality.
