Introduction

Overview

The ZR310 is a community repeater panel (Figure 1-1) which provides individualized repeater service for up to 70 customers or customer groups on a single RF channel. It acts an interface between a GM300 transmit radio, and a GM300 receive radio, providing TPL and DPL encode/decode, repeat audio processing, and all timer functions. An internal database holds the various attributes associated with each user group. Nearly all of the ZR310's functions can be customized for each of the 50 TPL tones and 20 DPL codes.

You can program all of the functions of the ZR310 in three ways:

•Remotely, using DTMF over the radio channel

•Locally, with the Motorola RIB compatible interface for connection to a computer

•By using a touch-tone telephone

Standard Features

The following is a list of ZR310 Community Repeater Panel features.

•Decoding / Encoding for 50 TPL tones and 20 DPL codes.

•Remote control and programming via DTMF radio, or DTMF from a telephone plugged into the programming jack.

•Remote enable / disable of all user groups.

•Per-user programming.

•Cross-tone, cross-code, tone-code encoding.

•Privacy made prevents "barge-ins".

•Vacant tones and codes can be reserved.

•Courtesy tone.

•Automatic station ID per user.

•Accessory PTT input with selectable TPL / DPL encode.

•Repeater set-up / knockdown remote DTMF commands.

System Configuration

Unlike a conventional community repeater panel. which usually consists of a system card (or equivalent circuitry) and up to 70 different plug-in tone cards, the ZR310 incorporates one card that allows system and user programming.

System Functions

System programming replaces the system card in a conventional community repeater panel. The system function controlled by the ZR310 software are listed below:

•System Access Code

•Repeater Set-up / Knockdown

•Time-out Timer

•Courtesy Tones Frequency

•Anti-Kerchunker Filter

•Station ID

•Speed, Timer, Frequency

•Program Mode Access Code

•Accessory PTT TPL / DPL Encode

•Carrier Repeat ID
