The single rack design of the GTR 8000 Expandable Site Subsystem (ESS) houses up to 6 channels with RF distribution and power systems. Factory-configured and tuned to your specific system, it makes installation quick and easy. Connect multiple ESS racks to achieve maximum site capacity. May 28, 2012 The GTR 8000 can be configured to operate with the GCM 8000 Comparator, using IP network transports in an ASTRO 25 network. The GTR 8000 can also be configured to operate with the ASTRO-TAC 3000, with V.24 circuit transport connectivity. Consult the G-Series Product Planner for more details. . GTR 8000 Base Radio Description on page 35 provides a high-level description of the GTR 8000 Base Radio and the function it serves on your system. GTR 8000 Base Radio Theory of Operation on page 63 explains how the GTR 8000 Base Radio works in the context of your system.

Configurations
ASTRO 25 & Analog Conventional: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 Trunking: 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.

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
