GTR 8000 Base Station/Repeater

Features

MULTIPLE P25 CONFIGURATIONS

	ASTRO® 25 Trunking GTR 8000 Expandable Site Subsystem (ESS), Motorola's premier turnkey RF site design, provides the optimal P25 trunking solution for easy installation and high availability. All base radios, networking equipment, timing and frequency distribution, RF combining and multi-coupler equipment are factory integrated into a single rack or cabinet.	ASTRO® 25 & Analog Conventional Motorola's Conventional channel solutions range from small single repeater sites to wide-area coverage voting and simulcast systems. The GTR 8000 Base Radio’s high performing analog capabilities enable narrow-banding migrations that maximize audio performance.
	ASTRO® 25 Data Motorola’s Integrated Voice and Data (IV&D) in ASTRO® 25 trunking and conventional systems as well as High Performance Data (HPD) are supported by the GTR 8000. Voice and data transmissions switch dynamically on the same base radio for ease of use.




ROBUST PLATFORM

	Performance • Maximum Coverage Multisite Linear Simulcast offers industry-leading coverage with fewer sites • Receive Diversity Two branch diversity receiver expands talk-in coverage for HPD and TDMA trunking • Superior Audio 100 ppb frequency stability directly enhances analog audio performance	Availability • Dual Connections All channels remain online and on air in the event of a network switch or timing/frequency reference failure • Battery Revert and Charging Eliminates need for an uninterruptible power supply (UPS) in many installations
	Installation & serviceability • Easy Install Ships factory aligned ready for installation • Hot Swap Hardware Service and replace hardware without system down-time • Online Software Download Download software while online and fully operational • Front Serviceable Perform all servicing from the front of the station	Space efficiency • Compact Hardware Standalone deployment utilizes a 3 rack unit chassis • Reduced Number of Racks and Cabling Expandable Site Subsystem conserves power and space by integrating controllers, switches, cavity combining, TX filtering, multicouplers & preselectors into one vertical cabinet/rack • Front Access Connections Install within inches of the wall and save valuable site space
	Life expectancy • Future Ready No new hardware required to convert for narrow-banding, from conventional to trunking, from FDMA to TDMA, or from single to multi-site configurations • Software Defined Radio Upgrade to new functionality through software updates and configuration changes	Security • Password Protected Password-only, user/password, and RADIUS server authentication configurations are supported • Secure Connectivity Secure SNMPv3 and secure shell (SSH) IP connectivity provided with Microsoft Windows® Configuration Service Software • Robust, Hardened IP Stack Built to comply with Department of Defense STIGs for secure network communications
