LTE POTSwap and Voice Services

POTS Replacement - Replace your plain old telephone service (POTS) with cellular enabled fixed or mobile implementations!

The Janus LTE POTSwap allows users to replace analog (copper) phone lines, also called POTS (plain old telephone service) or PSTN (public switched telephone network), with a cost-competitive POTSwap unit and cellular voice and data plans. The POTSwap converts your fixed location landline devices to cellular enabled fixed or mobile implementations.

POTS Replacement with a POTSwap is the easiest way to switch legacy equipment from traditional phone landlines to a 4G LTE network. The existing phone line is connected directly to POTSwap. Simply unplug the telephone jack from its wall outlet and plug it into the POTSwap’s RJ11 socket. Insert the appropriate SIM card into the back panel of the unit. 

POTSwap™ Carrier Certifications Regulatory Approvals

The POTSwap includes several cellular carrier and regulatory approvals and certifications, as stated in our Product Briefs, User Manuals, and other documentation. Ultimately, the customer is responsible for ascertaining and abiding by the Federal, State and local laws, regulations and other requirements regarding the application in which they will deploy the POTSwap
