VIDA System Infrastructure Clause Samples

VIDA System Infrastructure. System Overview‌ The following sections provide a summary of system components:  The Network Switching Center (NSC) is located at the Hebron Water Tower with a second NSC located at FB2 (▇▇▇▇▇ Street Water Tower) for geographic redundancy. This north-south geographic split increases the survivability and fault tolerance of the network. The secondary NSC tracks the activities of the primary so that it is prepared to take over network switching duties at any time. Switchover between the primary and secondary is automatic in the event of failure of the primary. Each NSC switch will be equipped with a primary server (VIDA Management Server (VMS)), which hosts all the required system applications of the VIDA network. Additionally each site has a Unitrends backup system for rapid recovery in the event of loss of the local server data. There will be two (2) dispatch centers; the new consolidated dispatch center and a back-up which is also the Carrollton PD dispatch center. The consolidated dispatch center will have 10 operator consoles for the four (4) cities and two (2) training consoles. The Carrollton PD back-up center will have seven (7) consoles.  A Unitrends server located at each NSC provides automatic/continuous backup of critical databases (radio, talkgroups and infrastructure) on and off site locations.  An Exacom Logging Recorder is located at the primary and back-up dispatch centers to provide centralized recording for the proposed system. Each dispatch center will have two clients able to access the logging recorder.  The Carrollton Radio Shop provides monitoring of the system with the VVMS, which hosts the Unified Administration System (UAS) and Regional Network Manager (RNM). This capability is also available at the Carrollton dispatch center.  The system will consist of a P25 Phase 2 Simulcast system utilizing six (6) TX/RX sites, each consisting of ten (10) RF channels (18 talk paths), at Hebron ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇ Water Tank, FB1 (Justice Center Water Tank), FB2 (▇▇▇▇▇ Street Water Tank), Spectrum Center and Wagon Wheel Water Tank.  An IP Simulcast Control Point is located with each NSC, one at the Hebron Water Tank, the other at FB2.  All TX/RX sites reside on a microwave loop ▇▇▇▇▇▇ has designed the microwave system so all sites reside on the loop. The microwave system will connect the six (6) TX/RX sites, two (2) dispatch centers, and the radio shop. ▇▇▇▇▇▇▇ ▇▇ is connected via a microwave spurs going to the Addison EOC. Farmers Bran...
