Copper retirement is here. What is riding on your POTS lines, and what to do about it
Major carriers across the country are actively retiring copper infrastructure, the POTS lines that still carry fire, alarm, elevator, fax and voice services. At the same time they are sharply raising off-contract rates to push customers off. Here is what that means for your sites, and how we take an organization from “we are not sure what we have” to a clean cutover.
About this article
Nimbl Networks is a technology advisory firm based in Dallas, Texas, that helps multi-site organizations design, negotiate, implement and support telecom and managed services. This article is written by an advisor, for the leaders who are weighing the decision.
What the carriers are doing, and why it matters now
POTS stands for “plain old telephone service”: the analog line delivered over a copper pair that carried dial tone for a century. The major carriers are retiring that copper network across the country. Where copper is retired, the services riding on it are withdrawn or moved, and new copper orders are no longer taken in many areas. Under the FCC’s network change rules, an incumbent carrier must file public notice before retiring copper, and that notice becomes final 90 days after the FCC publishes it unless an objection is filed. In 2019 the FCC also granted forbearance from the rules that required the largest incumbents to lease analog copper loops to competitors and to resell services at wholesale discounts, with a transition that ended in August 2022.
The second half of the program is pricing. Lines that fall off contract move to tariff rates, and those rates have been rising dramatically, year after year, specifically to encourage customers to transition. Many organizations first notice copper retirement as an invoice that has quietly doubled, not as a notice. By then the carrier’s timeline, not yours, is driving the project.
What is actually riding on those lines
Voice is the obvious case and often the smallest one. At a typical multi-site organization the copper carries:
- Fire alarm panels dialing a monitoring center, which are regulated and inspected.
- Burglar alarm and security panels.
- Elevator emergency phones, also regulated and inspected.
- Fax in healthcare, legal, logistics and finance workflows.
- Voice: the main number at a small site, the fallback line behind the phone system, the lobby courtesy phone.
- Point-of-sale terminals, gate and door entry, building controls, utility meters and backup management ports.
Almost none of this appears on an IT inventory as “copper.” It appears as a monthly charge nobody questions, often on an invoice that goes to facilities, a branch manager or accounts payable rather than to IT.
Three answers for every line: keep, disconnect, migrate
The decision is simple once the facts are in front of you. For each line:
- Keep it. A few lines still have a working wireline option worth holding, at least for now, at a known rate.
- Disconnect it. A surprising share of lines serve equipment that was removed years ago. Confirm nothing is on the far end, disconnect, and stop paying.
- Migrate it. Move the service to a different technology: a cloud voice platform for people, and a cellular or IP-based POTS replacement device for alarms, elevators, fax and point-of-sale, with battery backup and a monitoring company that accepts it.
The hard part is not choosing. It is knowing what you have, where it is, what it is for and what it costs. That is the audit.
How we run it
We do the pre-work, so the decision in front of you is a short one.
- Audit the environment. We review every account and site and highlight the services that are impacted by retirement, by repricing or by both.
- Evaluate the invoices and the customer service records. The invoice shows what you are paying; the carrier’s customer service record (CSR) shows what is actually installed and under what terms. The two rarely match, and the gap is where disconnected lines keep billing and where contracts have silently expired.
- Prepare a full inventory for your review. Every line, by site, with the address, the circuit, the equipment it serves, the current rate and the contract status, so you can mark each one keep, disconnect or migrate without a research project.
- Finish the pre-work before any provider is involved. Regulated lines (fire, elevator) are flagged for the alarm company, the elevator contractor and the inspector. Replacement requirements are written per class of line, not per site, so the replacement is one standard rather than a dozen.
- Engage the alternative provider and oversee the transition. We bring in the replacement provider against a written scope, sequence the cutovers (install the replacement, test with the monitoring center, then disconnect the copper, never the other way round) and act as your advocate until every site is live.
- Follow up on the retirement of the old billing. Disconnect orders are where charges linger. We confirm that each retired line has stopped billing, and dispute the ones that have not.
Who delivers the replacements
The replacement is delivered and billed by the provider that fits each class of line. We use providers such as AT&T, Spectrotel and Ooma to facilitate legacy service transitions, chosen per line for coverage at the site, the device’s fit for the equipment (alarm panels and elevator phones have specific requirements), battery backup, and acceptance by the monitoring company. Because we do the inventory and the requirements first, the provider is quoting against facts rather than discovering them during the install.
When to start
If a site has received a retirement notice, the clock is already running. If not, the price trend alone usually justifies starting now, because the same inventory work is needed either way, and the regulated cases take the longest to schedule. A reasonable goal for a multi-site organization: a complete inventory this quarter, life safety replacements scheduled next, and voice lines moved as part of any cloud voice project already on the roadmap.
Done well, copper retirement is also a clean-up: every unknown line resolved, every invoice matched to a site, and a smaller bill at the end of it.
