About this file
This is a technical specification document for MD FiRST (Maryland's FirstNet-related communications infrastructure) detailing hardware and licensing requirements for the Barton RF Site, an all-garbled simulcast cell operated by the State of Maryland. The specification outlines a comprehensive radio communications system including core expansion licenses (ASTRO 25 FDMA, P25 Phase 2 TDMA, Dynamic TG Assignment, and UNC device licenses), D-Series Multicarrier Radio equipment with six simulcast trunking licenses and TDMA licenses, and three dynamic channel assignment licenses. The system includes dual D-Series multichannel power amplifiers with two-year post-installation warranty, an RFDS transmitter system with splitter combiner and transmission filter, an RFDS receiver system with dual diversity featuring two site receiver multicouplers and preselectors, two DSC8500 site processors with integrated GNSS timing and Rubidium modules, network infrastructure including two SRX345 routers, alarm systems with Netguardian controls, two seven-and-a-half-foot equipment racks, and extensive power distribution components. The specification identifies six operational frequency channels with specific transmit and receive frequencies, designating channels 1 and 2 as active with frequencies ranging from 769.21875 MHz to 799.96875 MHz.
The document specifies a complete DC power plant solution utilizing a Trilogy Power System with 48V/300A-500A capacity, five 2000W rectifiers, four 48V 125Ah battery strings, dual 1500VA inverter modules, and comprehensive circuit breaker distribution with 20 fuse circuit positions. Spare parts requirements include multiple field replaceable units (FRUs) covering critical components such as MCPA modules, transceivers, site processors with Rubidium timing, splitter combiners, and power supply modules to ensure system redundancy and operational continuity. The specification does not indicate pricing terms, set-asides, or funding sources, focusing exclusively on hardware and licensing components required for system installation and operation at the Barton site.
