Last week the FCC slowed Verizon's plan to pull copper out of 662 wire centers. Read it as a few months' grace, not a change of direction. The last business users of copper aren't desk phones. They are fire alarm panels, elevator cars and gate controllers, and almost nobody in IT has them on a list.
On September 26 the Federal Communications Commission declined to let Verizon's latest copper retirement application go through on autopilot. The filing, submitted in August, covers 662 wire centers across Arizona, Delaware, New Jersey, New Mexico, Ohio, Rhode Island, South Carolina, Utah and Virginia, most of them inherited from Frontier. Ohio alone accounts for 245 and Virginia for 211. The commission's explanation was a single line: it "requires additional time to complete its review."
The pressure came from state regulators and members of Congress, and their argument was about households. Representative Suhas Subramanyam put it plainly: "A senior in Rappahannock County with no cell signal and no fiber at her house is not clinging to old technology." That is a real problem, and it is the one that will get the hearing.
The business version of the same problem is quieter, and in most companies it has no owner at all.
A pause, not a reversal
Nothing about the direction of travel has changed. Carriers want out of copper because it is expensive to maintain and serves a shrinking base, and federal policy for the past two years has made retirement faster, not slower. AT&T stopped taking new copper voice orders in October 2025 and has said it intends to retire the large majority of its copper footprint outside California by the end of 2029. Verizon's own notice for 59 Arizona wire centers, dated September 8, sets retirement "on or after December 10, 2026."
That notice contains the sentence operations leaders should actually underline: Verizon "may require customers and interconnecting entities to migrate services off of copper facilities well before the copper retirement implementation date." The date on the notice is the latest a line works. It is not the date you plan to.
So the FCC's pause buys time in nine states for one carrier. Anyone treating it as a reason to defer is misreading it.
Where copper still lives in a company
Ask a CIO whether the company still runs on copper and the honest answer is usually no. The desk phones went to VoIP a decade ago. The contact center is in the cloud. The data network is fiber and 5G backup.
That answer is correct about the things IT bought. It is wrong about the building.
The analog lines that remain in most enterprises are attached to devices that were installed by contractors, specified by code, and paid for out of a facilities or occupancy budget. The fire alarm panel dials a monitoring center over a phone line when a sensor trips. The emergency phone in each elevator car is a plain analog handset. The gate at the distribution center, the door-entry intercom at the clinic, the intrusion alarm at the branch, the fax machine in the pharmacy, the dial-up card terminal at a low-volume site, the telemetry modem in a pump station or a building management controller. Many network teams also kept an analog modem on core routers for out-of-band access when everything else fails.
These lines share three properties that explain why they get missed. They are cheap individually, so nobody reviews them. They are critical rarely, so nobody tests them. And they sit between departments, so nobody owns them.
Where copper hides
Device | Usually owned by | What happens when the line dies | Question to ask this quarter |
|---|---|---|---|
Fire alarm communicator | Facilities, alarm contractor, sometimes the landlord | Panel can no longer reach the monitoring center; the building may be treated as unmonitored | Has the replacement path been accepted by the local fire authority? |
Elevator emergency phone | Facilities, elevator service contract | A trapped passenger's call goes nowhere | Does each car have a tested replacement with backup power? |
Intrusion and access alarms, gates, intercoms | Security, site operations | Silent failure until an incident | Which panels still dial out, and to whom? |
Fax and dial-up terminals | Business unit, store operations | Orders, prescriptions or payments stop at specific sites | Which sites still depend on them, and for what volume? |
Telemetry and building controls | Engineering, OT, energy management | Readings and alerts stop arriving | Which controllers report over a phone line rather than IP? |
Out-of-band modems on network gear | Network operations | The recovery path is gone when it is needed most | What replaces it, and is that path independent of the main network? |
Editorial assessment, not survey data. Ownership varies by company; the pattern of split ownership does not.
The bill knows the line exists. Nothing knows what it does.
The obvious place to start an inventory is the telecom invoice, and it will tell you something useful: how many analog business lines you pay for, at which addresses. What it won't tell you is what is plugged into the other end. A line labeled with a phone number and a street address could be the fire panel, a forgotten fax, or nothing at all.
That gap is where the real work sits, and it is physical. Someone has to walk the site, trace the line to a device, and record the device, the contractor who services it, and whether a code or insurance requirement attaches to it. In leased buildings, some of the critical lines will be on the landlord's account, not yours, which means your exposure depends on someone else's inventory.
Replacement is not a SIM swap, either. Copper lines draw power from the carrier's central office, which is why the phone in the elevator works during a blackout. Their wireless and VoIP replacements depend on local power and batteries, which was the core of the objection the lawmakers raised. For life-safety devices, the replacement communicator generally has to be acceptable to the local fire authority, and lead times for contractors and inspections lengthen as every business in a region hits the same deadline at once.
Who is most exposed
The risk scales with the number of sites, not the size of the company. A software firm with two offices has a short list. A retailer, a bank branch network, a clinic group, a restaurant franchisor or a logistics operator may have several lines at each of hundreds of locations, a mix of owned and leased buildings, and a patchwork of local alarm contractors.
Utilities and water operators carry a second layer: remote telemetry that predates IP and was never on the IT asset register because it was never IT.
For these businesses the failure won't arrive as one outage. It will arrive as a scatter of individual sites going quiet over eighteen months, each discovered by a failed inspection, an alarm that didn't report, or a store manager who notices the card terminal stopped dialing out.
What this means for leaders
Before the next carrier notice lands
Name one owner. Facilities owns the devices and IT owns the carrier relationship. Give the program to one of them, with the other accountable for their half.
Inventory from the bill outward. Pull every analog line from carrier invoices, then map each to a device on site. Lines that map to nothing are savings; lines that map to life-safety equipment go to the top of the list.
Plan to the migration date, not the retirement date. Carriers have said they may require customers to move well before the published date.
Ask landlords and contractors directly. Request their line inventory for your sites in writing. Their gap becomes your incident.
Budget per site, not per line. Communicators, batteries, contractor visits and inspections cost more than the monthly line ever did.
The FCC will spend the next few months hearing about rural households without fiber, and it should. Nobody is going to hold a hearing about the elevator in your Columbus warehouse. That one is yours to find.
