The FCC has already acted to get the country off aging copper. Carriers are already discontinuing service in phases. The lines that kept your operation stable can now become the lines that hold it back — unless you choose the next network on your terms.
The conference rooms look current. The analog circuits that still hold the building together often do not. Those circuits earned their place. They also need a designed successor.
You already know how to run a stable building. This is the five-step inventory that lets you keep that stability while the plant underneath changes.
A new fiber lateral with the same exposed edge is only half a modernization. The replacement for aging lines has to include how the building is reached, authenticated, and monitored.
The logo on the circuit is not the strategy. Coverage, build, SLA, and the work after install decide whether the upgrade holds.
