Legacy Transport

ATM, Frame Relay, Token Ring and multilink serial — the transport generation the career started on, retained here because the record should show what the work actually was.

Also known as ATM, Frame Relay, Token Ring

Left to right is time. Each row is one of the 9 disciplines this one worked alongside, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that used this technology is counted, so what shows here is the company it kept rather than the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.

Troubleshooting and configuring ATM, Frame Relay, Token Ring and Fast Ethernet at Coleman Technologies from 1999, and bonded multilink serial on the GE intercontinental telemetry network.

These are obsolete and the entry is not a claim to current skill. It is here because a career record that quietly drops the technologies it began on misrepresents the shape of the journey — and because the habits formed on constrained, expensive, unreliable links are exactly the ones that made later designs assume a circuit would fail rather than hope it would not.
