10. SEAMLESS 5 -CHANNEL WEST MULTI -SITE <br />Adding a 5 -Channel trunking operation to this site allows for <br />a more efficient use of 5 channels and ensures available <br />channel capability. Rather than 2 channels that must be <br />manually patched to communicate to any unit in the eastern <br />system, this "multi -site" system allows roaming from east to <br />west without operator intervention (manual switching). <br />11. 15 -CHANNEL HOT STAND-BY <br />Utilizing the existing Hobart Park site, a 15 -Channel stand-by <br />system would come on-line in the event of failure of the <br />simulcast mode of operation, or more often during routine <br />preventative maintenance. <br />12. ADDITIONAL INSTALLATION/ENGINEERING <br />The following equipment must .be installed, documented and <br />engineered to provide adequate operation of the 800 MHz <br />system: <br />• 4 -Channels of Mutual Aid and associated antenna system <br />• 3 additional consoles and switch interfaces <br />• 10 digital voice interface modules (all mobile and <br />portable digital encryption <br />• 35 digital modems <br />• Jessica phone patch <br />• UPS system <br />• 2 -site controllers for multi -site operations <br />• 15 channels with antenna system at Hobart Tower <br />13. INCREASE TO A 20 CHANNEL COUNTYWIDE SIMULCAST SYSTEM <br />Additional costs to modify the proposed 15 channel simulcast <br />system in the eastern county and the 5 channel multi-site- <br />system <br />ulti-sitesystem in the western county to a county -wide 20 channel <br />simulcast system. <br />14. EDACS DATA GATEWAY AND MDT MESSAGE SWITCH <br />These two devices work in tandem within the system backbone to <br />route data between remote Mobile Data Terminals/laptop <br />computers and the data servers (NCIC, CAD, and computer <br />files). <br />15. An SYSTEM <br />The Automatic Vehicle Locator (AVL) is a vehicle monitoring <br />system incorporating a vehicle mounted -sensor that transmits <br />the vehicle's ever changing longitude and latitude coordinates <br />to an AVL computer interfacing with the CAD computer at the <br />Central Dispatch Center. An example of this feature is the <br />ability to divert an ambulance returning from a transport to <br />the hospital to another EMS call outside their zone because <br />they are the closest unit. The AVL system costs include the <br />AVL master computer, GIS maps, and 20 vehicle sensors. The <br />system is capable of monitoring up to 250 vehicle sensors. <br />16. VOICELESS STATUS AND MESSAGING SYSTEM <br />The Voiceless Status and Message System allows the dispatchers <br />and the field units to send and receive messages between the <br />dispatcher's console and the field MDTs with the push of a <br />button. Routine tasks, such as announcing a unit is en route, <br />arrived at the scene, or available for another call can be <br />sent without voice communications. Building diagrams, <br />hazardous materials information, and Specials Needs <br />Information are other examples of messages that can be <br />transmitted to the field MDTs. <br />Commissioner Eggert advised that each of the Commissioners had <br />met with staff and studied the report very carefully and that she <br />was deeply committed to it. <br />65 <br />December 19, 1995 <br />BOOK 96 PAGE 8:35 <br />
