1998 – 2000
CommScope and SYSTIMAX
The structured cabling under every switch of the Cabletron years: certified on AT&T and Lucent's SYSTIMAX in 1998, a brand CommScope would own from 2004.
The earliest credential in the record, and the only one about the physical layer. In 1998, two years into the Cabletron Systems years of field engineering and instruction in São Paulo, the AT&T and Lucent SYSTIMAX Structured Cabling System Engineer certification was earned: the design and installation discipline for the copper and fibre plant that every hub, switch and router of that era plugged into. The brand had been Bell Laboratories' Premises Distribution System of 1983 and AT&T's SYSTIMAX SCS of 1989; by 1998 it belonged to Lucent, in 2000 it passed to Avaya, and in 2004 CommScope bought it, which is why the credentials page lists the issuer as CommScope.
Why a network engineer learned cabling, 1998
A Cabletron field engineer of the late 1990s spent as much time in wiring closets as at consoles. The MMAC hubs and SmartSwitch chassis were installed where a building's horizontal cabling terminated, and the faults that reached the vendor's engineer were as often a cross-connect, a run past its length or a bad termination as a configuration error. SYSTIMAX was one of the structured-cabling systems the enterprise buildings of the time were built on: a hierarchy of equipment rooms, backbone and horizontal cabling and work-area outlets, with rules for each, a design method and a warranty attached. Certifying on it meant being able to read a building's cabling design, specify what a new floor or a new chassis needed, and tell a customer which half of a problem was theirs.
Teaching the physical layer
The same years were the first teaching years, and structured cabling was the layer the Cabletron Internetworking Technologies classes started from: media, connectors, distances and the categories of twisted pair, before a single frame was switched. The 1998 credential gave that first module an authority it would not otherwise have had, and the habit of beginning at the cable plant stayed with the teaching. The credential expired in 2000, the year the chapter itself ended with the move to Riverstone Networks in California.
