OVERVIEW
The RTU-292 Radio/Telephone Interface Unit provides an adjustment-free
automatic connection between a radio system and telephone or other two-wire
line. The unit is suited for use with HF, VHF, UHF or satellite systems and
is applicable to full duplex or half-duplex or simplex modes. The unit’s
full-featured telephone set, monitor speaker, and flexible switching allow
numerous operating scenarios.
DESCRIPTION
A keypad allows DTMF or dial-pulse signaling the built-in handset is
pushbutton-selectable for use with either the telephone or the radio. Since
the telephone may place and receive calls, it’s easy
for the operator to establish a phone patch connection. Once a link is established, the operator may communicate with either
party using the RTU-292’s handset, or may monitor both
sides of the conversation with the speaker. The auto-dial/auto-answer function enables users to dial into an unmanned
radio station equipped with an RTU-292. The user inputs control data via
the telephone DTMF keypad which the RTU-292 uses to control the radio equipment.
Remote users may use this function to make calls (phone patches) with other
radio stations. Also, users may enter data via their telephone DTMF keypad
to command a radio station to contact another radio station and to dial a
phone number into another telephone system. This function works with HF, HF-ALE,
VHF, and UHF radio systems.
