POTS IN A BOX® is a multi-network POTS replacement router supporting LTE, cellular, Wi-Fi, PSTN, and FirstNet Band 14 connectivity. It enables legacy analog services including voice, fax, fire and security alarms, DTMF signaling, M2M communications, and analog modem data. These functions—traditionally delivered over copper POTS lines—are securely transported over LAN/WAN internet connections, fiber, cable, LTE cellular networks, and FirstNet, ensuring reliable performance for critical communications.
The POTS IN A BOX® models can be used on Verizon and AT&T cellular networks. All PIAB devices are dual SIM-capable, meaning that you can install SIMs from both networks into the PIAB devices for network diversity and failover redundancy.
POTS IN A BOX® 90X1 and 90X2 include built-in battery backup for up to 48 hours of operation. Actual runtime varies based on usage, connected devices, and network activity.
Specialty lines include fax machines, fire and burglar alarm panels, point-of-sale systems, and analog modem data lines. Elevator lines may also be considered specialty lines when used for monitoring or automated check-in functions. If an elevator phone is used solely for standard voice calling, it is typically classified as a voice line.
POTS IN A BOX® installations are typically completed within a few hours, depending on each customer’s use case. MIX Networks delivers a hassle-free deployment experience through a nationwide network of in-field technicians who handle site surveys and on-site installation. Our onboarding team manages provisioning and activation, with U.S.-based support available anytime after go-live.
POTS IN A BOX® supports a wide range of critical communication use cases, including VoIP over WAN or LTE, analog fax, fire and security alarm signaling, auto-dial call boxes (ring-down), and gate or access control communication systems.
