Frequently Asked Questions
What does a copper retirement notice mean for businesses in Maryland?
Carriers are retiring traditional copper telephone infrastructure in parts of Maryland. Businesses using POTS lines for alarm systems, elevators, fax machines, point-of-sale terminals, or traditional phone service should review the applicable carrier notice and plan a replacement before the stated date.
How much notice is given before a copper shutdown?
Notice periods and implementation dates vary by carrier and filing. Some notices state a specific implementation date, while others establish a planned retirement without a final service date. Begin planning for POTS replacement as soon as a notice is filed for your wire center.
What are my options to replace POTS lines in Maryland?
Common POTS replacement options include VoIP or SIP trunking where reliable broadband is available, and managed wireless POTS replacement such as POTS Link, which uses cellular connectivity and works well for alarm systems and remote locations. The right option depends on the equipment, site conditions, and applicable code requirements.
How do I know if my address is on a retirement list?
Use the POTS Wire Center Shutdown Tracker to search the public wire-center notices for your area. The official carrier notice is linked from each tracker record.
