Add Interconnect to Simplex Radio System
The Model 30 World Patch is a low cost open channel telephone interconnect designed for installation on a simplex radio.

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.
APO (advanced programming operation) provides 50 autodials, automatic autodial via 4-click PTT, landline security code for direct air access, FET relay, and other features.

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
100-call and 1000-call two-tone and DTMF paging. For ordering convenience, the Model 30 Worldpatch is available in three different versions:

1. Basic with APO (901-9416) —recommended for half-duplex repeater operation, includes Advanced Programming Option (APO)
2. Basic with APO & Digital Voice Delay (901-9417)—as (1) above with digital voice delay for simplex operation on base stations or control stations
3. Basic with APO, Digital Voice Delay, and Selective Calling (901-9540) —as (2) above, but recommended for applications requiring selective calling on repeater or base stations Any version can be changed into another by ordering a field upgrade kit. Other options include a 19-inch rack mount bracket, Deadbolt surge arrestor, and various interface cables for the connection to the radio. An assortment of connection diagrams explains the hookup to the most popular radios. A responsive technical support department is also available to provide expert assistance over the telephone.

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.
The radio interface is a 10-pin modular plug with crimp pins provided. Level settings for transmit, receive, and carrier adjust are accessible on the back panel. All programming settings may be changed by remote control, without visiting the site. Programming takes place from a Touch-Tone telephone or keypad-equipped radio. Access to the program memory is protected by a programming access code. The installer may restore the unit to the factory default settings at any time.
