Docusign Envelope ID:A05892FB-E22F-4F9D-8892-114F73CBF1B7 <br /> 21 <br /> • (1)GRV8000 Comparator <br /> • (1)Juniper SRX Network router <br /> • (1)Juniper Ethernet switch <br /> • (1)TRAK 9100 redundant modular frequency and timing standard <br /> 2.2.2 911 Communications Dispatch Consoles <br /> The MCC7500 consoles currently installed at the Primary Dispatch Center will interface to <br /> the new simulcast system equipment Prime Site comparator. The GRV8000 comparator acts <br /> as a four wire audio interface to the consoles and and IP intercace to the network and RF <br /> stations at the RF sub sites. <br /> 2.2.3 Orange County Simulcast VHF RF Sites <br /> The final RF sites ultimately to be used for the final county wide VHF simulcast paging network will <br /> be determined by Orange County and will be selected from sites being utilized as part of the new P25 <br /> simulcast network. The sites for phase one of the VHF Simulcast Paging network that are to be used <br /> with equipment included in this proposal are listed below: <br /> 2.2.3.1 Eno Mountain Site: <br /> New equipment will be installed inside the existing equipment building. A tower stress and <br /> loading analysis will be performed to determine the status of the tower and feasibility of installation <br /> of new VHF Antenna System. <br /> Any costs related for structurally upgrading or improving the equipment shelter or tower shall <br /> be the responsibility of Orange County and is not reflected in the costs for this proposal. <br /> Equipment to be located at the site includes: <br /> • (1)VHF GTR8000 radio <br /> • (1)RF VHF antenna and transmission line <br /> • (1)TRAK 9100 redundant modular frequency and timing standard <br /> • (1)SRX345 Network router <br /> • (1)Juniper Ethernet switch <br /> 2.2.3.2 Chatham Mountain Site: <br /> New equipment will be installed inside the existing equipment building. A tower stress and <br /> loading analysis will be performed to determine the status of the tower and feasibility of installation <br /> of the new VHF Antenna system. The new antennas system will be installed at approximately five <br /> hundred foot elevation on the UNC TV Tower. The lower level will be support simulcast networks <br /> and minimize simulcast interference issues. This will also allow the Radio equipment to be installed <br /> in the building at ground level eliminating servicing issues with the current Radio equipment that is <br /> mounted on equipment platforms high on the tower <br /> Any costs related for structurally upgrading or improving the tower shall be the responsibility <br /> of Orange County and is not reflected in the costs for this proposal. <br /> Equipment to be located at the site includes: <br /> • (1)VHF GTR8000 radio <br /> Orange County,North Carolina July 19,2024 <br /> VHF Paging System Upgrades Use or disclosure of this proposal is subject <br /> to the restrictions on the cover page. <br /> © Motorola Solutions Confidential Restricted System Description 2-3 <br />
