Interconnect to Simplex Radio System
The Model 30 is an ideal way to add telephone interconnect to
simplex radio systems for low power in-plant applications. Its low
cost and simple operation make it well suited to applications in
smaller radio systems. INTRODUCTION
The Model 30 Worldpatch is a compact,
telephone interconnect that allows a group of two way
radio users to place and receive telephone
calls. It efficiently interfaces a telephone line (or
analog PBX line) to a simplex base station, control
station, or conventional repeater. It can also be
used as a repeater maker to convert a pair of
mobile radios, or a full-duplex base station, into a
carrier-operated repeater.
The Model 30 is available both as a single-group
interconnect as well as a selective-calling
interconnect. The selective calling version provides
INSTALLATION & MOUNTING The Model 30 is compact enough to fit
in the industry's smallest repeater enclosures, including the
Motorola Radius GR300, GR500, and GR1225. Radio-specific cables are
available to make the interface as quick and easy as possible. For
proper installation in standard, 19-inch rackmount enclosures, an
optional 19-inch rack mount bracket is available. The phone line
connection on the rear of the Model 30 is a simple RJ-11 phone jack. Features
Selective Calling option:
