BOOK 96 P, u 834 ATTACHMENT B 800 MHz INFORMATION/DEFINITIONS 1. 10/2 SYSTEM Signifies the original system design of 10 channels trunked and simulcast in the eastern portion of the county and 2 channels conventional/non-trunked in the western portion of the county. 2. MUTUAL AID Since the original system design in 1993, the Florida Division of Communications has modified the design requirements for mutual aid channels. Failure .to comply with new design criteria will result in the loss'of the FCC licenses due to non-compliance with known standards. 3. ADDITIONAL CONSOLE Staff was directed by the BCC to add three (3) additional consoles to the original system design pricing --two (2) for the City of Vero Beach and one (1) for the City of Sebastian. The municipalities recognize that they are responsible for costs related to the connection and installation into the County's Console Switch. 4. DIGITAL FEATURES Certain agencies presently have encryption features within their existing communication systems. Law enforcement agencies utilize these features for drug enforcement and investigations. Other agencies needing this everyday capability include Emergency Medical Services for the purpose of maintaining patient confidentiality when communicating with the hospitals, Fire Services for the purpose of fire investigations, bomb threats; and hazardous materials communications. The installation of digital features during the design phase is much cheaper than redesigning the system for these features at a later time. 5. TELEPHONE PATCH The 1993 -"system design was predicated on enhancing communications to the public safety agencies, whose existing communications systems did not provide for a telephone interconnect. The recommended system merges the needs of the public safety agencies with other general service agencies who use the telephone interconnect for daily services. Without a telephone patch, the proposed system would reduce available features and would require another means for authorized phone patch users. 6. UNINTERRUPTED POWER SUPPLY (UPS) The original system design provided a minimal UPS system for on-site computer memory retention only. The recommended system ensures a continuous, and transparent operation to the user, radio service when electrical outages occur, such as lightning strikes and "brown -outs". It allows the emergency generator to start and safely transfer the load. from commercial power to emergency power and then back to commercial power when available. 7. WEST TOWER SITE The original design only included two towers east of I-95 with an existing tower being -utilized for coverage in the western Part of the County. The propogation study concuded a third tower would be needed in the West County as existing towers were in the wrong locations to achieve the level of coverage necessary for the Turnpike and Fellsmere area. 8. 15/5 SYSTEM Signifies the Ericsson system design that utilizes 15 channels and simulcast in the eastern portion of the county and 5 channels trunked multi-sited/seamless in the western portion of the county. 9. INCREASE To A 15 CHANNEL SYSTEM, In March of 1993 the user survey performed by -Pallans Associates dictated a system design of 10 -Channels for the East end of the county. The latest survey, November 1995, indicated .an increase to 1,565 users. A 10 -Channel system would be insufficient to handle the increase (572 units). The total frequency allocation available to Indian River County is 20 channels (10 existing and 10 pooled (NPSPAC]). Of these 20 channels, 15 have been designed to operate on the East coast in a simulcast mode; the remaining 5 channels will be trunked seamlessly in the western portion of the county. 64 December 19, 1995
