The Zetron Model 45B is a microprocessor-based radio-to-telephone interconnect. It’s designed to provide flexible operation as a full-featured telephone patch with selective calling, ANI decode, and advanced airtime billing features.
The Model 45B interfaces a radio system to the public telephone system for interconnected conversations. It also provides selective calling of mobile radios and pagers from the telephone system or from other mobile radios. An RS-232 serial port allows on-screen manipulation of all system and user information. Remote DTMF (Touch-Tone) programming is also supported.
The Model 45B is designed for radio common carriers, co-ops, utilities and private systems where a number of different users need to share the system yet receive different service and separate accounting.
