1.1 OVERVIEW

This document describes the DRB-25 Dual Radio Base Station system installation procedures, configuration and operational details.

The DRB-25, shown in Figure 1-1 and Figure 1-2, is a compact, multi-mode transceiver package which provides users with one or two analog or APCO Project 25 digital radio channels. The small size and high level of flexibility of the DRB-25 make it an ideal solution for any organization starting out on the digital migration path.

Installation and Operator Handbook Introduction

Figure 1-2 Rear View - DRB-25

The DRB-25 provides one or two independent radios in a single package. Each radio can be used as a base station or a repeater, and may be configured to support both APCO Project 25 compliant digital subscribers as well as providing backwards compatibility to analog users. This means that existing mobile radio equipment need not be immediately retired.

Each radio may be configured to provide an analog interface (2 wire with loop or ground start or 4 wire with E & M signaling) to the public switched telephone network (PSTN), to a private branch exchange (PBX), or to existing tone based remote control units.

The DRB-25 provides the key elements of an APCO Project 25 RF Sub-system including the air interface (Um), interfaces for telephone and PBX interconnect (Et) and host data systems (Ed). Support for Ethernet based network management, digital consoles and the APCO Project 25 fixed station interface (Ef) will be available as software upgrades.

Installation and Operator Handbook Introduction

The DRB-25 provides the following features:

• Automatically and concurrently supports the digital mobile and FM analog radios (TIA/EIA 603

including CTCSS selective calling).

• VHF (136-174 MHz) or UHF (400-470 MHz) frequency bands.

• 60 W or 125 W RF output.

• Configurable as singl e or dual channel with any mix of frequency bands a nd output power levels.

• 512 programmable channels per radio, with each channel programmable as APCO Project 25 digital or

TIA/EIA 603 analog.

• Programmable channel scan of up to eight channels.

• Optional RS232, RS485, Ethernet and general purpose I/O interfaces.

• Optional 2 wire or 4 wire + E&M wire line interfaces for remote control or telephone interconnect.

• Compatible with industry standard tone remote control consoles.

• Compatible with Microwave Links using 4 Wire and E & M signaling.

• User friendly Windows configuration and diagnost i c software for local or re mote configuration.

• Self test diagnostic routines.

• 240/110 VAC or 12, 24 or 48 VDC versions.

• Available as a standard 19” rack mount sub-rack, as a desktop unit or housed in a secure floor mount

cabinet.

In addition, the DRB-25:

• Enables a gradual migration from analog to digital terminals, or from one frequency band to another,

communicating across-mode and across-bands while the migration is taking place.

• Provides link radio functions to other base stations or repeaters for geographically remote areas.

• Enables upgrade from a single-channel to dual-channel at low cost.

• Provides a low cost upgrade path from the dual-channel to a multi-channel base station.

1.2 PHYSICAL ARRANGEMENT

1.2.1 General

The DRB-25 is a completely self-contained cabinet unit housing all the components necessary to support one (single-channel) or two (dual-cha nnel) radio configurations. The basic housing is provided with feet for desktop use and may optionally be supplied with mounting brackets for rack-mounting. Alternatively the entire unit may be installed in a secure cabinet.

Integral to the housing are the system power supplies, fans and airflow control for cooling of modules and a common backplane into which the Transceiver, Controller and Interface Modules are plugged . A singlechannel DRB-25 requires one Controller Module and the following plug-in modules:

AMX–MA–00651 Issue 0.02 (USA)

Page 5

Installation and Operator Handbook Introduction

• One Transceiver Module.

• One Power Amplifier Module.

• One Power Supply Module.

• One Interface Module (Optional - depending on external interfaces).

A dual-channel DRB-25 requires one Controller Module and the following plug-in modules:

• Two Transceiver Modules.

• Two Power Amplifier Modules.

• Two Power Supply Modules.

• One Interface Module (Optional - depending on external interfaces).

A single-channel DRB-25 can be easily and inexpensively converted to a dual-channel DRB-25 by the installation of the additional modules.

The DRB-25 may be configured for AC or DC power sources, or as AC power with DC revert in the case of AC power failure.

A block diagram of a DRB-25 is shown in Figure 1-3.

1.2.2 Configuration Options

The DRB-25 may be configured a s a Conventional ( i.e. non-trunked) single or d ual-channel rad io base station. The configuration options are summarized in Tables 1-1 to 1-3

Crossbanding Repeater

Crossbanding and Crossmoding Repeater

The DRB-25 is configured with a single Transceiver, PA and Power Supply. If a mobile radio makes a call on the Transceiver’s assigned frequency, the signal is repeated using the same format (analog or digital) used by the mobile.

The DRB-25 is fitted with two Transceivers, PAs and Power Supply Modules. If a signal is received on the assigned frequencies of either of the Transceivers the signal is repeated in the same format in which it was received. Both Transceivers operate independently and two signals may be repeated simultaneously although not on the same frequency.

transceiver is programmed with up to 8 channels which can be any mix of frequency and operating mode (analog/digital). The transceiver scans through the list of programmed channels until a valid signal is detected from a mobile when the signal is repeated using the same format (analog or digital) used by the mobile.

The DRB-25 is fitted with two Transceivers and PA Modules which have operating frequencies in different bands. When a Transceiver receives a mobile call on its assigned frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver transmits the call on its assigned frequency in the user-programmed mode (analog FM or APCO Project

25). The DRB-25 is fitted with two Transceiver Modules which have operating

frequencies in the same band. When a Transceiver receives a mobile call on its frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver transmits the call on its frequency in the user-programmed mode (analog FM or APCO Project 25).

The DRB-25 is fitted with two Transceiver Modules which have operating frequencies in different bands. When a Transceiver receives a signal on its assigned frequency it repeats it using the same format, and passes the audio to the other Transceiver. The second Transceiver operating in a different band to the first transmits the call on its assigned frequency in the user-programmed mode (analog FM or APCO Project 25).

Diagnostics using DRB-25 Diagnostic Monitor (ZDM)

A PC running TMP is connected to the front panel serial port of either transceiver module to upload programming information into the DRB-25. TMP may also be used remotely using a dial-up modem (future option).

A PC running ZDM is connected to the front panel serial port of the Controller Module which enables both transceivers to be monitored and diagnostic checks to be run. The serial ports may also be used to connect the DRB-25 to a digital console (future option). ZDM may also be used remotely using a dial-up modem (future option).
