VIPER implementation does not have a <br />firm schedule, except as identified in TABLE 3-1. By the end of 2005, the <br />majority of VIPER radio sites providing Orange County radio coverage <br />are planned to be operational. The next major effort can begin as early as <br />2005 to develop purchase specifications for equipment required to <br />complete OCEM and UNC-CH Public Safety PSAPs. Once the PSAPs are <br />completed and operational on VIPER, subscriber equipment may be <br />purchased for VIPER by participating entities. <br />7.3.2 Long-Term Cost Comparison <br />TABLE 7-2 shows a cost comparison for the Private 800 MHz trunked <br />system; VIPER assuming UNC-CH Services purchased a separate digital <br />800 MHz trunked radio system and VIPER assuming UNC-CH Services <br />remains on their legacy systems. The table provides yearly cost for the <br />first 10 years and a cumulative cost for 10 year and 15 year for each of the <br />three scenarios. Maintenance cost estimates for each scenario begin 1 year <br />after the year equipment was purchased. <br />The cost for the Private system includes all 800 MHz trunked <br />infrastructure, console equipment, microwave equipment and subscriber <br />equipment in the initial purchase. <br />'' Section 7 -Comparison of Private System and VIPER <br />'~^~ Page 34 of 43 <br />~..,, <br />
