Carriers are retiring the copper POTS network — but your elevator phones, fire alarm dialers, and intrusion lines still need a working line to stay code-compliant. FieldSparc plans and installs POTS-in-a-Box (PIAB) so your life-safety systems keep answering, long after the copper's gone.
The old analog phone network is being decommissioned. Carriers are filing to retire copper POTS, rates on remaining lines are climbing fast, and "the line just works" is quietly becoming "the line is gone." The systems that depended on that line don't stop needing it — and most of them are the ones a fire marshal or elevator inspector actually checks.
A POTS-in-a-Box is a managed, cellular-backed device with battery backup that hands your existing equipment the exact analog dial tone it expects — no rewiring your elevator, no ripping out the fire panel. We survey what you've got, cut it over cleanly, and hand you the documentation.
Code requires two-way voice in the car. When the copper drops, so does compliance — PIAB keeps the emergency line live and inspection-ready.
Fire alarm communicators still lean on POTS to reach the monitoring center. We keep the path up so your panel stays reporting and in code.
Burglar and access panels that dial out over analog lines keep their connection through the cutover — no gaps in coverage.
Older PBX and key systems still wired for POTS keep ringing. If it terminates on a 66 block, we've worked on it.
Entry callboxes, gate controllers, and courtesy phones that rely on a line — migrated without a truck-roll for every unit.
The analog odds-and-ends that still matter — kept alive or planned onto a modern path, your call.
We trace what's actually terminated — elevator, fire, intrusion, phones — down to the 66 block, and map which lines are load-bearing.
The correct device and port count for your line load, with battery backup sized to keep life-safety up during an outage.
We punch it in, move the lines, and verify dial tone and end-to-end signaling on every system — not just "it hums."
Labeled blocks, a line map, and test results — so the next fire or elevator inspection is a formality, not a scramble.
From the demarc to the last 66 block, we own the whole path — MDF, IDF, riser, and station drop. If the carrier’s copper ends at your building, we’re the team that keeps everything past it alive.
This isn't new ground for us. We've handled copper-retirement and POTS-replacement work across a wide range of sites and standards, and we know these systems from the panel to the punch-down.
Tell us what's on copper — elevators, fire, alarms, phones — and we'll bring a cutover plan and a straight answer, not a pitch.
