POTS Line Replacement Dallas: The Complete 2026 Guide to AT&T’s Copper Shutdown
POTS line replacement Dallas businesses once put off for “someday” now has a deadline. AT&T is shutting down its copper network across Texas, one wire center at a time. When your wire center goes dark, every device on those copper lines stops working. That includes desk phones, fax machines, alarm panels, and elevator emergency phones.
This guide puts everything in one place. It covers the shutdown timeline, the systems at risk, your replacement options, typical costs, and a step-by-step plan. In short, it gives a DFW business what it needs to move off copper on its own schedule.
What Is a POTS Line?
POTS stands for Plain Old Telephone Service. It is the analog phone network that has run over copper wire since the late 1800s. A POTS line carries your voice as an electrical signal from your building to a carrier switch.
For decades, copper was the most reliable option around. It worked without the internet. It even kept working through many power outages. As a result, businesses hooked far more than phones to it. Today, those same lines often serve fire panels, alarms, fax machines, elevator phones, and gate call boxes. That is why POTS line replacement Dallas projects often uncover lines nobody knew existed.
Why AT&T Is Shutting Down Copper in Texas
The short answer is cost. Copper is old, hard to repair, and serves very few customers. In fact, AT&T says its legacy copper base has shrunk to about 1 percent of its customers. Meanwhile, fiber and wireless networks cost far less to run and do far more.
Federal rules have changed, too. In March 2025, the FCC cut the customer notice period for copper retirement from 180 days to 90 days. Then, in March 2026, it adopted a new order that makes it easier for carriers to retire copper. You can read the FCC’s overview of how it is modernizing phone networks. Because of these changes, shutdowns move much faster now. As a result, POTS line replacement Dallas timelines have shrunk.
The AT&T Copper Shutdown Timeline
Here is where things stand as of October 2026:
- October 15, 2025: AT&T stopped taking new copper POTS orders in affected areas. It also stopped moves, adds, and changes on existing lines.
- June 2026: AT&T began tearing out copper in about 500 wire centers. That is roughly 10 percent of its network.
- October 2026: AT&T reports it has powered down more than 100 wire centers. It has also ended copper service in more than 500 communities across 18 states.
- By December 2026: AT&T has FCC approval to shut down more than 30 percent of its wire centers.
- End of 2027: AT&T expects about half of its wire centers outside California to stop serving customers.
- By 2029: AT&T plans to retire most of its copper network.
Texas sits at the center of this shift. One industry tracker counts 458 Texas wire centers on the shutdown list, more than any other state. For that reason, POTS line replacement Dallas planning can’t wait for a letter in the mail.
What the Shutdown Notice Means
AT&T mails a formal notice to the billing address on file. It lists the affected numbers, the service address, and the shutdown date. Under current rules, the final window can be as short as 90 days.
However, the notice won’t tell you which systems will fail. It also won’t flag fire code or elevator code issues. That work falls on you. Worse, the letter often lands in accounting instead of with the person who runs the building.
The Cost of Waiting on POTS Line Replacement Dallas Projects
Copper bills are climbing even before the shutdown. We often see POTS lines that once cost $30 to $60 a month now billed at $150 to $400. Some rates jump 50 percent or more with little warning. For a building with ten copper lines, that adds up fast.
Repairs are slowing down as well. Fewer techs work on copper now, and parts are harder to find. A fault that once got same-day service may now wait days. For an alarm panel or elevator phone, that delay is a real safety risk. In other words, waiting costs money every month and adds risk.
Which Systems in Your Building Use POTS Lines?
Most DFW businesses have more copper lines than they think. Each one needs its own POTS line replacement Dallas plan. Here are the usual suspects.
Business Phone Lines
Analog phones and older PBX systems often reach the outside world through copper lines. When those lines go, calls in and out stop.
Fax Lines
Medical, legal, and financial offices still lean on fax. These lines are easy to forget because they rarely cause trouble. For the details, see our guide to fax line replacement in Dallas.
Fire Alarm and Security Panels
Many panels use copper to reach a monitoring center. This is the highest-risk line in most buildings. Also, standard VoIP is usually not an approved fix under fire code.
Elevator Emergency Phones
Code calls for a working emergency phone in every elevator cab. If the copper line dies, so does your compliance. So, bring your elevator service company into the plan early.
Gate, Entry, and Call Box Systems
Older entry systems and gate controls often dial out over copper. Each one needs its own review.
POTS Line Replacement Dallas Options: What Works for Each Line
No single fix covers every line. Instead, match each line to the right replacement.
1. Cloud Phone System (Hosted VoIP or UCaaS)
For your main business phones, a cloud phone system is the standard choice. Calls run over your internet connection, and your provider runs the system in the cloud. You also gain auto attendants, mobile apps, voicemail to email, call recording, and AI call summaries. NTi installs Intermedia Elevate for most DFW clients. Learn more about our cloud hosted phone systems.
Typical cost: $20 to $45 per user per month, based on features.
2. SIP Trunking (Keep Your Existing PBX)
Does your premise phone system still work well? If so, SIP trunking can replace the copper lines and keep your PBX in place. Your phones, extensions, and call flows stay the same. For a closer look, read our breakdown of SIP trunking vs. hosted VoIP.
Typical cost: $15 to $25 per channel per month.
3. Cellular POTS Replacement
For alarms, elevators, gates, and other single lines, a cellular unit is usually best. These devices, often called “POTS in a box,” plug into your existing analog gear. They carry the signal over LTE or 5G instead of copper. As a result, the panel keeps working with no new wiring. Still, life-safety lines must pass NFPA 72, ASME A17.1, and local code review before cutover.
Typical cost: $20 to $40 per line per month, plus a one-time device fee.
4. Cloud Fax
Cloud fax sends and receives faxes through email or a web portal. It removes the copper fax line for good. HIPAA-ready options exist for healthcare offices.
Typical cost: $10 to $30 per month, versus $50 to $150 for a copper fax line.
This table sums up a typical POTS line replacement Dallas project.
| Copper line | Best replacement | Typical monthly cost |
|---|---|---|
| Main business phones | Cloud phone system | $20–$45 per user |
| Working premise PBX | SIP trunking | $15–$25 per channel |
| Fire alarm, security, elevator, gate | Cellular POTS replacement | $20–$40 per line |
| Fax | Cloud fax | $10–$30 |
Don’t Forget the Cabling Behind the Walls
Here is a step many businesses miss. A cloud phone system runs on your data network, not on copper phone lines. So the cable inside your walls suddenly matters a lot.
Older buildings often still run Cat5e or worn-out cable. That can cause choppy audio and dropped calls once voice moves to the network. You may also need extra drops, since many desk phones need their own network port. Our guide to VoIP network requirements explains what to check.
For that reason, we review cabling and phones in the same POTS line replacement Dallas project. That means one crew, one plan, and one point of contact. If your network needs work, our sister company Just Cabling handles structured cabling across DFW.
Your POTS Line Replacement Dallas Action Plan
Follow these five steps before a notice sets your deadline.
- Audit your bills. Look for line items like “Business Access Line,” “analog,” “POTS,” “RCF,” “ISDN BRI,” or “single-line business service.” Each one points to a copper line.
- Walk the building. Check the electrical room, elevator machine room, server room, and front entry. Then note every device with a phone line plugged in.
- Ask AT&T about your wire center. Your rep can tell you if your address is on the retirement list. If it is, your clock is already running.
- Match each line to a fix. Use the options above. Next, flag any life-safety lines for code review with your alarm and elevator vendors.
- Schedule the cutover. Plan cabling, install, testing, and staff training. Finally, switch over on your timeline, not AT&T’s.
Frequently Asked Questions
Can I keep my business phone numbers?
Yes. Your numbers can move to a new provider through number porting. We handle the port, so incoming calls keep working. Here is how business number porting works.
Will my phones work if the internet goes down?
Cloud phones can send calls to mobile apps during an outage. For extra safety, add a backup internet or cellular link.
Can I ignore the notice and keep paying for copper?
No. Once AT&T retires a wire center, copper service there ends for good. You can’t renew it.
Is this only an AT&T issue?
No. Verizon, Lumen, and Frontier have also filed to retire copper. However, AT&T serves most of North Texas, so it drives most POTS line replacement Dallas work.
