POTS line sunset in Southern CaliforniaWhat the copper retirement means for elevator, alarm and call box lines.

TELMOVE Insights · November 2026

Most buildings still have a handful of copper phone lines that nobody thinks about until one stops working. Many of them are tied to life-safety equipment: the emergency phone in each elevator car, the fire alarm panel, the gate call box. The phone companies are retiring that copper, and California is now part of the plan.

This is a general overview as of November 2026, not legal or code advice. Carriers and regulators set the areas and dates, and they can change. Check the notices from your own carrier for your address.

What "POTS sunset" means

POTS stands for plain old telephone service: the copper analog phone line. A POTS sunset is a carrier retiring those copper lines and moving customers to fiber, wireless or internet-based service. Retirement happens area by area, so there is rarely one shutoff date for a whole region. Prices on the copper lines that remain have also been rising, which is why many buildings replace them before a notice arrives.

The national picture

In March 2025 the FCC took a series of actions to streamline the process carriers use to retire copper networks, and it has continued to look at further changes. AT&T has said it is working to exit its legacy copper network operations across the large majority of its wireline footprint by the end of 2029.

What is happening in California

California has been the exception, and it is changing. According to the California Public Utilities Commission (CPUC), on May 20, 2026 AT&T applied to the FCC to discontinue its legacy copper landline voice service for residential and business customers in portions of 360 wire centers in California, affecting about 184,000 residential and 15,000 business customers by AT&T's count, on or after June 1, 2027. Affected customers are federally required to receive a notice from AT&T. The CPUC has challenged parts of AT&T's plans, and the state and federal rules are still being worked out. The CPUC keeps a public page on the AT&T applications and the affected wire centers.

For a building owner, the details of the regulatory fight matter less than the direction. Copper service is going away area by area, and the lines your building depends on need a replacement plan before the notice arrives, not after.

Which lines in your building are affected

• Elevator emergency phone lines (see elevator phone line replacement)
• Fire and burglar alarm communicator lines
• Fax lines and modems
• Gate, door and parking call boxes
• ATM, point-of-sale and hallway emergency phones
• Older phone systems still running on copper lines or PRIs

Why the elevator line is the one to fix first

When a copper line is cut, the elevator phone in the car usually looks normal. The failure shows up when a passenger presses HELP, or when an inspector tests it. An elevator emergency phone needs a working line that still behaves like a standard phone line to the phone, a correct location for dispatch, and a test with the answering point after any change. If the phone itself is failing, see elevator phone repair.

A checklist for Southern California buildings

1. List every analog line in the building, its phone number, its bill and the device it serves.
2. Watch for carrier notices about copper retirement at your address, and keep them with the line list.
3. Press HELP in each elevator car (with your elevator contractor if needed) and confirm who answers and whether they get the correct location.
4. Ask your alarm company what communication path your panel needs if the copper lines go away.
5. Cancel lines that no longer serve anything, and replace the rest on your schedule, before the carrier's.
6. Test every replaced line at the receiving end, and keep records for inspections.
