POTS Replacement Is a Mission-Critical Job — We’ll Help You Get it Right


America’s network of copper-wire phone lines—commonly known as POTS, which stands for plain old telephone service—is based on analog technology and a copper-wire network.

Plain old telephone lines were introduced in 1876. This analog telecommunication was the standard until 1988. It is still used currently, but all the major telephone providers have initiated their phase-out strategy.

Plain old telephone lines have served the population for generations. Still, many companies find that it’s time to gradually replace them with a universal broadband system that meets the communication needs of the 21st Century. 

POTS lacks the capacity and speed of modern technologies like Voice over Internet Protocol (VoIP)—and most people now use cell phones or internet-based devices as their primary communication devices, driving change in the telecommunications infrastructure.

The Sun Has Set on POTS Line Replacement End-of-Life


The FCC issued Order 10-72A1, which mandated all POTS lines in the US be replaced with an alternative service, such as fiber or wireless connections, by August 2, 2022. These lines are now decommissioned.

Rising costs of POTS services and more affordable cellular services are driving the trend toward POTS line replacement. The Bureau of Labor Statistics shows the cost of POTS lines increased by 27% in 2020. The cost of cell services dropped by half during the same period.

Many companies still rely on POTS technology. It is still being used for life-saving emergency communications that run natively on analog lines, including:

  • Fire alarm lines
  • Elevators
  • Phone lines (for low use cases or emergency lines)
  • Fax lines
  • Security systems

Our POTSolve solution provides TRUE dial tone and is a simple replacement for your current setup.

If your organization is relying on legacy landline networks, planning your POTS replacement now and obtaining convenience, service, and speed of digital systems is paramount to your success. Without POTS replacement, your organization won’t be able to get maintenance services or replace broken hardware that’s already deteriorating.

Connected Solutions Group (CSG) offers a 4G LTE (Long-Term Evolution) enterprise-class POTS replacement solution for a low monthly fee. Our service provides real-time insights into each phone line connected or other lines via a customer dashboard monitoring portal.

We Make Your Analog-to-Digital Transition Easy


Deciding you need POTS analog telephone lines replaced is easy. Think about the increased cost, the limitations of unified communications (UC), and the reliability requirements of emergency services that will otherwise plague your organization.

With the cost to maintain POTS lines and the decreased geographical coverage, you will see these factors drive up the costs of your services—forcing you to charge more. Customers are already experiencing cost increases as the transition to digital communications is happening, so why add to it?

Many people associate the 4G network with their cell phone service, but this is only part of its complete functionality. Leading solutions like POTSolve use enterprise-grade routers that optimize signals and minimize their signal-to-noise ratio, producing faster, more reliable service for you and your organization.

Additional benefits of 4G failover include its affordability and flexibility since you can implement it rapidly compared to wired connections.

Standard POTS Lines Application

For your basic needs, such as Fax, just the Analog Telephone Adapter (ATA) is needed. We program your phone number directly into our software and route your call to its destination for you. This software simply needs power and Internet, which the POTSolve Bundle can assist with.

Emergency and everyday services are complex and provide life safety services. We build the ATA into an enclosure with a battery for backup purposes and an LTE router for constant connection. 

We do this by connecting our RJ21X to your existing systems and provisioning your ATA for specific use cases, so you can offer reliable life-saving services without the hassle.

For elevators, it is a traditional hands-free phone that complies with the Americans with Disabilities Act (ADA) in each elevator cab. An elevator shaft is lined with concrete and steel, so a cellular transceiver must be located inside the shaft.

We provide these services for:

  • Fire alarm lines
  • Elevator controls
  • Voice lines (low use case), fax lines, and call boxes
  • ATMs
  • Metering

All of these lines can be managed in our portal and supported by CSG and our Managed Services offerings.

Eliminate Analog Lines and Upgrade Your Network for the 21st Century with POTSolve


Important systems run on analog devices and lines — emergency call boxes, fax machines, etc.

Starting Your Upgrade Journey from Analog Lines with POTSolve


Starting a POTS line replacement is easy.

POTSolve fills all POTS line replacement needs without buying multiple devices from multiple vendors. POTSolve integrates into existing communications infrastructure, replacing legacy POTS lines—burglar and fire alarms, fax, gate access, modems, and more.

Our POTSolve device also offers 1-to-1 integration and is fully programmable for custom use cases. This capability allows a computing device to easily detect a new hardware component without configuring it or requiring a user to resolve resource conflicts.

A host system compatible with your infrastructure exchanges data with its components through mechanisms like defined memory, direct memory access channels (DMACs), I/O spaceport addresses, and interrupt request lines (IRLs). Each device must be uniquely associated with these mechanisms to operate.

Analog signal phone service is delivered to you over a 4G LTE cellular network, providing you with the most comprehensive coverage of any mobile network nationally.

Compare reliable Internet connectivity from Verizon’s 4G LTE network to the aging copper in the ground that, in some places, is over 100 years old and susceptible to failure.

Choose POTSolve To Help You Stay Connected


Technological advances like cell networks contribute to a steady decline in POTS networks. The quality of POTS lines is deteriorating with less incentive from telecoms to maintain them. 

Now, landline costs are tripling or quadrupling in some areas, with an expected upward trend as analog telephone lines approach their end of life.

VoIP is a common solution for many POTS applications, but it generally fails to meet the high-reliability requirements for emergency services. Connected Solutions Group’s POTSolve devices provide analog voice communication over a 4G/LTE network for no CAPEX, allowing you to begin saving money immediately. 

Our devices also have the redundancy needed to replace POTS for virtually all applications, including emergency services.

Analog signal phone service is delivered to you over a 4G LTE cellular network, providing a reliable connection that won’t get disrupted by local hazards. POTSolve saves money, provides redundancy and better reliability, and ensures fire panel compliance.

Perform your POTS line replacement with ease from POTSolve.
