Does retiring a copper line mean replacing every device connected to it?

Not necessarily. A network can become obsolete while the equipment using it stays perfectly functional. An elevator emergency phone may still do exactly what it was installed to do. A fire panel may still meet the organization's needs. The problem is not the device. The problem is that it was built to communicate through a network its carrier no longer wants to maintain.

The catch is timing. When a carrier retirement notice arrives, it gives you ninety days. That is enough time to execute a plan you already have. It is not enough time to build one from scratch across multiple sites, with equipment orders, compatibility testing, and code inspections competing for the same calendar.

Key takeaways

• There is no single national copper shutoff date. Carriers retire copper market by market, wire center by wire center, so your effective deadline is set by your carrier's notice.
• Under 47 CFR §51.333, a carrier must generally give at least 90 days' notice before retiring copper facilities still in service. The FCC's March 2026 order removed the steps that used to extend the timeline in front of that notice.
• Fire alarm and elevator communications are governed by codes — NFPA 72 and ASME A17.1 — written around a specific analog connection. A standard VoIP line does not automatically satisfy them.
• Most businesses cannot say what is attached to each of their POTS lines. The monthly bill lists phone numbers, not endpoints.
• The audit is the part you can do before any notice arrives, and it converts a ninety-day scramble into a ninety-day schedule.

What did the FCC change in 2026?

On March 26, 2026, the FCC adopted the Network and Services Modernization Order (FCC-26-19A1). It eliminated the filing and approval steps that once let competing carriers and state regulators stretch a copper retirement out over months or years, and it preempted conflicting state rules.

The notice requirement itself survived. Under 47 CFR §51.333, a carrier must still give at least 90 days before retiring copper that is in service, and as little as 15 days for copper not currently serving a customer. What changed is that the ninety days is now most of the runway rather than the last stretch of it.

Carriers are moving accordingly. AT&T stopped accepting new POTS and specialty line orders across 18 states in October 2025, began decommissioning copper facilities in roughly 500 wire centers — about 10% of its footprint — in June 2026, and has publicly stated its intent to retire virtually all of its copper by 2029. Verizon, Lumen, Frontier, and CenturyLink have filed retirement plans of their own.

What equipment is still running on copper?

For most businesses, copper retirement was never about office telephones. Plain Old Telephone Service lines still connect equipment installed years ago for safety and compliance reasons, and that equipment tends to live in places nobody visits.

• Fire alarm panels reporting to a central monitoring station.
• Elevator emergency phones in machine rooms and cabs.
• Building-entry and gate systems with analog intercom lines.
• Security and burglar alarm panels using dial-out reporting.
• Fax machines in accounting, HR, or medical records.
• Backup and emergency phone lines kept for outage scenarios.

These lines occupy the gap between departments. IT does not manage fire alarms. Facilities does not track telecom invoices. Finance pays for "misc. phone services" at the third location without asking what it covers.

Why does a standard VoIP swap fail for life-safety systems?

Life-safety systems are not analog by habit. They are analog by code. Fire alarm communication falls under NFPA 72. Elevator emergency communication falls under ASME A17.1. Both were written assuming a specific kind of analog connection exists, with specific signalling and supervision behavior behind it.

A standard VoIP line does not automatically satisfy either. It may produce a dial tone. It may pass a casual test. That is not the same as reliably transmitting alarm signals, supporting supervision, and passing inspection.

There is a second issue underneath it. Traditional copper service often kept working during a local power outage, because power arrived through the telephone network itself. Most digital alternatives depend on local equipment, which means the replacement's reliability becomes your responsibility. Backup power, network availability, cellular coverage, monitoring, and failover stop being assumptions you inherit and become design decisions you own.

So the standard for a life-safety replacement is not whether it works. It is:

• Does it correctly carry the device's actual signalling, not just voice?
• Does it stay up during a power outage, and for how long?
• Is it supervised and monitored, and does the monitoring center see it the way it expects to?
• Will the complete installation pass inspection under the applicable code?

Confirm compatibility with the alarm company, elevator provider, or responsible specialist before the original line is disconnected. Not after.

How do you inventory your remaining POTS lines?

Most businesses do not have a complete inventory of their analog connections, and the monthly bill is not one. It lists telephone numbers. It does not explain what is attached to them. A line installed a decade ago may terminate at an alarm panel, an elevator machine room, a utility closet, or an emergency phone that nobody in the current IT department knew existed.

That makes discovery step one. For each remaining POTS line, identify the physical endpoint and document the device, department, vendor, and business function attached to it. Then sort every line into one of four categories:

1. Still required and suitable for migration to a replacement connection.
2. Still required, but the equipment is due for replacement on its own merits.
3. No longer necessary and safe to disconnect.
4. Unknown and requiring investigation.

The third category usually pays for the exercise. Cost figures in this market are hard to pin down, since federal agencies and independent research firms no longer track POTS pricing and most published numbers come from replacement vendors. Ooma reports that $80 per line per month or more is typical for business copper service, with some organizations reporting significantly higher rates. Whatever your actual rate, lines in category three are billing you monthly for nothing.

When should you replace the equipment instead?

Sometimes replacing the device is the right call. A system may be genuinely obsolete, unreliable, unsupported by its manufacturer, or unable to meet current safety and regulatory requirements. A newer system may deliver capabilities the old one cannot.

But the disappearance of copper should not make that decision for you. Evaluate each system on its own terms:

• Is the existing equipment still reliable?
• Is it still supported by the manufacturer?
• Can it operate correctly over a digital or cellular replacement?
• Does the complete installation meet applicable codes and monitoring requirements?
• Is preserving it more practical than replacing the device, retraining users, and rebuilding established workflows?

This is an asset-management decision as much as a telecommunications one. Replacing the communications layer underneath a device can extend its useful life for years without forcing a facility-wide upgrade nobody budgeted for.

What are the POTS replacement options?

There is no single answer, and the right choice depends on what the line is doing.

• Cellular POTS-replacement gateways present an analog port to the existing device and carry traffic over LTE, often with wired internet as a secondary path. This is the usual fit for life-safety and specialty applications where the device must stay exactly as it is.
• SIP trunking with an analog gateway tends to make sense where the line is primarily carrying voice — a break-room phone, a warehouse extension — and where lower monthly cost and easier scaling matter more than code compliance.
• Dedicated POTS-in-a-box platforms consolidate multiple analog lines onto a single managed device, which is often the economical route for a building with a dozen or more lines to migrate.

None of these is automatically appropriate for every device or every building. Compatibility, power resilience, monitoring arrangements, and regulatory requirements still have to be verified per installation. The point is that the choice is not binary between keeping an aging carrier line and replacing every piece of analog equipment you own.

Copper retirement readiness checklist

• Do you have a documented list of every POTS line billed to the organization, by location?
• Has someone physically walked each facility to identify what each line actually connects to?
• Does every line have a named owner, department, and vendor associated with it?
• Do you know which wire center serves each building, and where it sits in your carrier's retirement schedule?
• For each life-safety line, have you confirmed a compliant replacement with the alarm company, elevator provider, or authority having jurisdiction?
• Does the proposed replacement have a backup power plan, and do you know its runtime?
• Have you identified lines that can be disconnected outright to stop unnecessary billing?
• Is there a written migration sequence you could execute inside a ninety-day window?

FAQ: FCC copper retirement and POTS replacement

Is there an FCC deadline for copper retirement?

No single national date exists. The FCC has streamlined the process carriers use to retire copper, but each retirement still happens locally, wire center by wire center. Your effective deadline is set by your carrier's notice, not by the Commission.

How much notice will I get before my copper line is retired?

Under 47 CFR §51.333, generally at least 90 days before copper facilities still in service are retired. Copper that is not currently serving any customer can be retired with as little as 15 days' notice.

Can I move my fire alarm panel to VoIP?

Not safely, and not as a default. Fire alarm communication is governed by NFPA 72, and a standard VoIP line does not automatically meet its signalling, supervision, and reliability requirements. Confirm any replacement with your alarm company and the authority having jurisdiction before disconnecting the copper line.

What does AT&T's 2029 target mean for my business?

It is the company's stated goal for retiring the bulk of its copper network, not your deadline. If your wire center is in an earlier phase, your line goes dark well before then. The relevant question is which wire center serves your building and where it sits in the schedule.

What if I do not know how many POTS lines we have?

That is the normal situation, and it is the strongest argument for starting the audit now. The monthly bill lists numbers, not endpoints, so identifying what is physically attached to each line requires someone walking the facility.

Bottom line: ninety days is a deadline for execution, not discovery

Nothing about this transition requires an indiscriminate equipment purge. Some devices genuinely need replacing. Some should be retired outright. Others have years of useful service left once they are moved onto a connection that suits them.

But that sorting takes time you may not have once a notice arrives. The audit is the part you can do right now, before anyone hands you a date. Every line found, every endpoint located, every device documented, every owner assigned. It costs nothing but attention.

The smartest modernization strategy is rarely to replace everything old. It is to know exactly which part of the system is actually obsolete — and to know it before someone else sets your timeline.
