About this file
This is a technical specification document for the Maryland FIRST (Flexible, Integrated, Real-time, Statewide, Trusted) radio system expansion at the Barton site, involving the State of Maryland. The specification details hardware and licensing requirements for a two-way radio infrastructure upgrade at the Barton All-Gar Simulcast Cell location. The project encompasses core expansion licenses including ASTRO 25 FDMA and P25 Phase 2 TDMA trunking, six D-Series Multicarrier Radios with simulcast and TDMA capabilities, RF distribution systems with diversity receivers, network equipment including two SRX345 routers, a Nokia SAR-8 MPLS system, alarm control units, and comprehensive power distribution systems. The specification includes detailed frequency control assignments across six channels (with channels 1 and 2 designated for both transmit and receive operations at 769.21875/799.21875 MHz and 769.96875/799.96875 MHz respectively) and a full range of spare field replaceable units covering critical components such as multicarrier power amplifiers, transceivers, preselectors, and power supply rectifiers.
The specification requires a two-year warranty following installation and mandates that certain items, including the Transceiver N+1 upgrade and Advanced Power Monitor components, be provided as separate line items for pricing purposes. The equipment configuration includes redundant systems for critical functions, such as dual DSC8500 site processors with integrated GNSS timing and Rubidium modules, dual GPS antennas with surge protection, and dual inverter modules for power continuity. The power infrastructure specifies a 48-volt DC system with multiple rectifiers, battery strings rated at 125 Ah, and inverter modules rated for 1500VA to 3KVA capacity. The document reflects a comprehensive, high-reliability infrastructure build-out designed to support statewide emergency communications and public safety operations across Maryland.
