Abstract

3Com commissioned The Tolly Group, as part of a broader multi-vendor NIC research and testing project, to evaluate the 3Com TokenLink III PCMCIA network interface card beyond simple price and performance metrics. The main focus of the project was to document how the adapter compared with industry norms in four practical areas that affect real-world ownership and deployment: compatibility with hardware and software environments, ease of installation and configuration, technical support resources, and network management capabilities.  

This December 1994 Technology Spotlight is an addendum to Tolly’s broader “Network Interface Cards – Beyond Performance” work and focuses specifically on the 3Com TokenLink III PCMCIA adapter. According to the product summary on page 1, the adapter is a Token Ring LAN card operating at 4 or 16Mbit/s and uses the PCMCIA form factor for portable systems. Tolly notes that the overall NIC project involved more than 20 cards spanning Ethernet, Token Ring, and FDDI products across ISA, EISA, MCA, and PCMCIA bus types, with the 3Com profile documenting the individual results for this model.  

In the features matrix on pages 2 and 3, the TokenLink III PCMCIA is shown as strong in several compatibility and support areas. Tolly indicates that 3Com provided a software and operating-system support list and a list of PC systems in which the card had been tested. The adapter supported NDIS 2 for DOS, NetWare 4.01 and 3.11 client support for DOS, and software-based configuration. It also included automatic driver installation from the utility and a diagnostic utility, though it did not provide flash-resident configuration utilities, an LED status indicator, or an upgradeable ROM.  

Technical-support findings were generally favorable. The profile shows support for a toll-free number, standard phone support during business hours, no-charge basic support, worldwide technical support, bulletin board system access, access to current driver versions, and supplementary files such as tutorials, documentation, and patches. Optional higher-tier services such as weekend support, 24-hour support, on-site support, and other extended technical support were available by contract. The report also notes that 3Com was in the process of converting its internet FTP server to a World Wide Web server, reflecting the period’s transition in online support delivery.  

The management section shows a more limited result set. Tolly indicates that the TokenLink III PCMCIA did not provide DMTF support, SNMP support, LAN Network Manager support, or proprietary management features, even though 3Com was listed as a member of the DMTF. Overall, the report presents the 3Com TokenLink III PCMCIA as a portable Token Ring adapter with solid compatibility documentation, practical client-driver coverage, and broad technical-support resources, while offering fewer advanced manageability features than some broader industry expectations.
