Applications

The Cayman 3220-H belongs to a line of early consumer and small-office DSL routers that were popular in the late 1990s and early 2000s, when DSL broadband first became widely available as an alternative to dial-up internet. Devices like the 3220-H allowed multiple computers on a small LAN to share a single DSL connection — a significant capability at the time. The four-port 10Base-T LAN switch handled local traffic while the DSL WAN port connected upstream to the telephone company's DSLAM. The serial Maintenance Console port was typical of the era, providing direct CLI access for configuration when the network path was unavailable. Today these units are primarily of interest for vintage networking collectors, legacy network lab environments, retro computing enthusiasts, and anyone maintaining or studying early broadband infrastructure from that generation of equipment.
