A QUANTAR IntelliRepeater can simply operate as a SmartZone remote voice channel or perform call processing activities at a SmartZone remote site while still acting as a voice channel.
Site space costs are reduced by eliminating a separate external device at the site to control the calls. The QUANTAR IntelliRepeater supports such SmartZone features as Dynamic Site Assignment and Site Variable Density allowing for infrastructure equipment savings at the remote sites. Low traffic areas within a SmartZone system can be covered with bunking technology in a cost effective manner.

Full-Featured Fault Tolerance
The QUANTAR IntelliRepeater has the capability to transfer call processing capabilities to another IntelliRepeater at the site without disruption in active calls and minimal change in system access time.
IntelliRepeater operation provides continuous bunking communications and retains all APCO 16 features at an individual site.

Continuous Duty Operation
The station is designed for continuous duty operation and may be operated at full-rated power, exceeding FCC specifications. Reliability is increased by providing longer station usage for the most demanding communications systems.

State-of-the Art Digital Receiver
The QUANTAR station's receiver module has been completely redesigned to provide flexible system design with easy installation and adjustment.

• The receiver is functionally independent from the transmitter allowing implementation of crossband conventional operation.
• User-programmable channel spacing to 12.5 kHz operation simplifies station migration to narrow band channelization plans.
• To reduce station installation and alignment time, only the conveniently frontmounted preselector on VHF and UHF stations requires tuning.
• Synthesized frequency generation allows for economical and easy-to-implement frequency changes.
• Truly wide-band receiver-4 MHz bandwidth on VHF and UHF stations allows for a greater range of frequencies.

Advanced Transmitter Design
The QUANTAR station's transmitter design meets and exceeds major global intermodulation specifications for stations placed at crowded antenna sites. Electronic adjustment of deviation and power improves performance and lowers cost by reducing manual tuning adjustments at installation. Modulation sensitivity and power output are adjusted on a per channel basis to provide improved performance in a variety of system configurations. QUANTAR station's transmitter is equipped with an internal wattmeter for ease in measuring transmit output power.

Built-in Single Circulator
The QUANTAR station has a single circulator included in every station to improve reliability by protecting against antenna mismatches and to aid in the reduction of interference caused by equipment at crowded sites.

Truly Compact Station
The entire QUANTAR station fits in a 5 rackunit-high card cage weighing only 55 Ibs. Motorola's state-of-the-art technology allows efficient use of site space since additional equipment can be installed in the same area, giving reduced site rental costs and improved system aesthetics.

Modular Mechanical Design
The QUANTAR station's card cage modules are easily removed and replaced for station upgrades or servicing. These Field Replaceable Units (FRUs) provide prompt communications recovery. System upgrades are easily performed by replacing a systemspecific functional module or in some cases by simply loading new software. Both short term and long term cost savings are realized in installation, system maintenance, and upgrades.

Switching AC Power Supply
Improvements in power supply technology yield a reliable, lightweight, switching power supply. The power supply can operate over a wide range of main voltages (90-280 VAC) and frequencies (47-63 Hz) anywhere in the world without modifications. Voltages are adjusted automatically to eliminate the chance of failure due to improper installation.

Convenient Connection Access
Routine service ports are all located at the front of the station. All primary installation connectors are located on a single backplane accessed through the rear of the station. Installation and maintenance can be performed quickly, minimizing set-up time and maintenance costs.
Programming
The QUANTAR station is based upon a flexible software design that allows programming and alignment through a personal computer and appropriate software. The user-friendly software simplifies the process of adjusting station characteristics, thereby minimizing station downtime.

Self-Test Diagnostics
On power-up and during operation, the QUANTAR station automatically initiates selftests without interfering with communications. The station conditions can be readily determined by viewing the light emitting diodes (LEDs) on the module front panels providing quick and easy visual appraisal of station status. Station alarm messages and self-designed test results are logged and accessed through the Radio Service Software. Maintenance information is at your fingertips.

ASTRO 9.6 KBPS Modem
The ASTRO 9.6 kilobit duplex modem allows the interconnection of ASTRO fixed equipment via telephone lines. In order to minimize the number of phone lines required in any system, the ASTRO modem allows for the processing of both digital and analog audio. The signal generated by the modem can also pass through standard narrowband microwave multiplex channels. The modem is designed to fit internal to the station chassis, eliminating the need for additional housing space.

Triple Circulator
This option is recommended for RFcongested transmitter sites where added isolation protection is required. It can be mounted in a rack or cabinet.

Battery Revert for Switching AC Power Supply
Battery back-up is offered as an option to provide uninterrupted station service in the event of a site power failure. The station operates on a single battery voltage in battery revert mode. The station aerates power as the battery voltage drops. Line supplies charge batteries independent of the power amplifier voltage. The battery revert option includes several new features as standard: Voltage Adjust, Battery Temperature Adjust, Battery Watchdog, Battery Overvoltage Protection, Battery Connection Protection, and Low Voltage Disconnect. These features help provide optimal charging voltage to the battery, lengthen the battery's life, reduce maintenance, and protect batteries from improper installation and voltage overcharging.

DC-DC Convertor
The DC-DC convertor has the ability to utilize 12 (20 and 25 watt models only), 24, 48, or 60 VDC sources. These sources may be positive or negative ground. The wide range of voltages allows the station to utilize site power sources which may be more economical or reliable than the available AC power source.
