Direct Answer
An estimated 35 million landlines remain in service in the U.S., including roughly 14 million business lines — and the systems riding on them (point-of-sale, elevator phones, fire alarm panels, first responder lines) are increasingly at risk as carriers retire copper infrastructure and maintenance costs climb. POTS digitization, using a specialized adapter that translates analog signals to digital over cellular networks, lets businesses preserve existing equipment while gaining dual-SIM failover and modern reliability.

As industries rely heavily on telecoms, digitizing old telephone lines is becoming a business imperative for manufacturing, retail, transportation, and other critical sectors.
Key takeaways
- An estimated 35 million landlines remain in service in the U.S., including about 14 million business lines.
- Copper network maintenance costs have grown up to ten times traditional rates as the infrastructure deteriorates.
- Critical systems — POS, elevator phones, fire alarms, burglar alarms, fax lines, first responder communication — still commonly depend on legacy lines.
- Public Utilities Commissions in multiple states have launched investigations into carrier service reliability complaints.
- Dual-SIM POTS replacement adds cellular failover protection specifically valuable for life-safety and remote-location applications.
Why legacy copper landlines are becoming a business risk
In today’s digital age, modernizing telecommunications is a global necessity. The issue of neglecting copper landlines recently reached a boiling point, with major telecom carriers being accused of failing to provide reliable service to customers.
Public Utilities Commissions in various states have launched investigations after receiving numerous complaints from residents and businesses about dropped calls, slow repairs during outages, and other service reliability issues.
The copper network problem extends beyond telecom
This issue isn’t confined to specific carriers or states — it has implications far beyond the telecom industry, touching sectors like manufacturing, retail, and transportation.
With an estimated 35 million landlines still in operation in the U.S. alone, including about 14 million business lines, there likely isn’t an industry entirely immune from the potential impact of aging copper infrastructure.
Why telecom providers are retiring copper lines
Major telecom providers worldwide have been discreetly retiring their physical copper lines over the past few years, transitioning toward a new digital era. This transformation benefits both carriers and the customers they serve: copper networks are expensive to maintain and increasingly unreliable. Their gradual deterioration has accelerated over the past decade, while maintenance costs have grown up to ten times traditional rates — making legacy copper lines increasingly untenable.
Aging telecom infrastructure creates safety and compliance concerns
The dangers of patching old telecom infrastructure resemble those posed by neglecting critical physical infrastructure like roads, bridges, and tunnels.
Despite being the network connecting many alarm systems, elevator phones, and first responder communication lines, copper wire infrastructure has been overlooked in recent federal infrastructure investment. This neglect could create serious consequences for businesses, property owners, municipalities, and public safety organizations.
Critical systems still dependent on legacy lines
| System type | Why continuity matters |
|---|---|
| Cash registers and point-of-sale systems | Revenue-critical; downtime directly affects the bottom line |
| Elevator emergency phones | Code-mandated life-safety communication |
| Fire alarm panels | Life-safety monitoring and first-responder notification |
| Burglar alarm systems | Security monitoring and signal transmission |
| Fax lines | Still required in healthcare, legal, and government workflows |
| First responder communication systems | Emergency coordination that can’t tolerate gaps |
Why POTS replacement is urgent
The urgency to digitize Plain Old Telephone Service (POTS) can’t be overstated. This transition — also known as POTS transformation or POTS replacement — is essential for maintaining uninterrupted critical communications.
Reliable telecommunications support business continuity, security, human safety, and regulatory compliance. Beyond reducing telecom expenses, digitizing copper landlines helps build resilience into the aging lifelines that still serve millions of people and businesses. Public safety organizations, including the New York Fire Department, have expressed support for this transformation.
How analog lines can be digitized
The technology behind this transformation uses a specialized adapter to translate analog signals into digital signals that communicate over major cellular networks. This approach lets businesses preserve existing analog equipment while moving away from aging copper infrastructure — offering primary connectivity for voice and data, plus wireless backup to help maintain business continuity during network and power outages.
Cellular failover adds an extra layer of protection
Dual-SIM functionality provides added failover protection to help ensure emergency lines remain connected during outages — especially important for life-safety applications, remote locations, retail sites, and facilities where downtime creates operational, financial, or regulatory risk. DataRemote’s POTS IN A BOX® is built around this same dual-SIM, multi-carrier approach.
Start planning your POTS replacement strategy
The future of telecom is digital. It’s time to stop delaying and paying more to maintain obsolete technology — copper landlines are becoming more expensive, less reliable, and harder to support.
Organizations that still rely on copper landlines should evaluate which systems remain connected to legacy telephone infrastructure and begin planning a transition strategy. By digitizing telecom lines now, businesses can reduce costs, improve reliability, strengthen continuity planning, and support critical communications well into the future.
