The Zetron Model 72 Extend-a-Line makes it easier than ever to deliver telephone service to nearly any remote location. Rural telephony, emergency service, and PSTN access from remote radio sites are all perfect applications for the Model 72. Provide your remote customers with a high performance telephone circuit using a pair of full duplex radios and the Model 72 Extend-a-Line.

Resellers will appreciate the ease with which they can configure and sell low density rural telephone systems. System operators with remote radio sites lacking telephone lines will find the Model 72 is the perfect means of extending the reach of the telephone network, and will appreciate the high quality audio. Extend-a-Line offers wide area telephone service without the requirement for expensive, foreign exchange (FX) telephone lines. Rural telephone companies can provide service to potential customers where wired service would be too expensive or simply impossible. Telephone companies will appreciate the Model 72’s low cost and simple radio interface, making the difficult task of providing emergency services much easier.

Installation of the Model 72 is as simple as connecting the Model 72 to the full duplex radio’s discriminator audio output, transmitter PTT, and transmit audio. The Model 72’s field programming makes configuration a snap, simplifying stocking requirements and contingency planning.
