In an era dominated by high-speed fiber internet and advanced enterprise phone systems, it might seem surprising that businesses still rely on traditional analog phone lines. However, despite all the advancements in telecommunications, certain critical systems still require plain old telephone service (POTS) lines to function effectively. Today, we’re taking a closer look at why analog lines remain relevant, particularly in essential services like fire alarms, security gates, and emergency elevator phones.
The Role of Analog Lines in Modern Infrastructure
Recently, I was in Corona, California, installing a new customer—Ergonomics, Comfort, and Design—a manufacturer of office chairs that distributes nationwide. While setting up their enterprise VoIP phone system, we were also installing analog lines for their fire alarm and security system. Many people don’t realize that despite widespread fiber adoption, key safety and security equipment still depends on analog connections.
Why? Because legacy systems, such as emergency phones inside elevators, require a stable, high-voltage connection—typically around 50V—to ensure a reliable dial tone for emergency calls. If you’ve ever been stuck in an elevator and needed to use that traditional phone inside, you were relying on an analog connection to reach emergency services.
The Challenge: Aging Copper Infrastructure
The issue is that major telecom providers like AT&T, Frontier, and Lumen are phasing out traditional copper-based POTS lines. Maintaining the aging copper infrastructure—some of which is over 50 years old—is too expensive, and these companies are shifting to fiber and wireless solutions instead. However, this transition presents a problem for businesses that still need analog connections for critical functions.
The Solution: POTS Line Replacement
This is where POTS line replacement technology comes into play. Our solution converts VoIP signals into an analog connection using an ATA (Analog Telephone Adapter), ensuring that older equipment like elevator emergency phones, security gates, and fire alarms can still function reliably over modern networks.
Here’s how it works:
- We bring in fiber connectivity (in this case, AT&T Business Fiber) as the primary internet source.
- The fiber connection is linked to an ATA adapter, which translates digital VoIP signals into analog signals.
- The setup includes a backup system with a built-in GSM modem. If the fiber connection fails due to a power outage, the system seamlessly switches to a 4G LTE network from Verizon, AT&T, or T-Mobile.
- A backup battery provides up to 36 hours of power, ensuring continuous service even during prolonged outages.
The Future of Analog Systems
While some businesses are moving towards GSM-based wireless networks for alarm and elevator systems, many still prefer the reliability of wired connections. As providers phase out copper lines, businesses will increasingly rely on solutions like our POTS line replacement to bridge the gap between legacy analog requirements and modern digital infrastructure.
