This modular IP approach substantially reduces the amount <br />of space needed for bacicroom electronics. All dispatch <br />activity is performed over IP. The physical space needed to <br />accommodate the MCC 7500 console position is comparable <br />to that required for a personal computer. <br />Both trunked talkgroups and conventional radii channels can <br />be accessed and controlled from one MCC 7500 IP Dispatch <br />Console over the same network. This reduces overall <br />transport costs and the need for duplicate fixed network <br />equipment. Table 1 -1 outlines the benefits of the MCC <br />7500's seamless integration to the ASTRO 25 network. <br />Table 1 -1: Benefits of Seamless Integration of the MCC 7500 IP Console with <br />Orange County's ASTRO 25 Network <br />Benefit to City of Sa nta Ana <br />Tight coordination between the IP Subscribers and console operators will be able to <br />network and IP console eliminates the communicate without loss of Information. <br />potential for audio degradation. <br />Emergency calls are prioritized for <br />be able to hear <br />Console operators wilqrn <br />successful delivery regardless of <br />emergency calls from the field. <br />network traffic. <br />Inherent access to all system resources <br />Console operators wil be able to reach out to <br />within the network provides dispatch <br />users in the field, <br />priority to reach any user when needed. <br />Rapid call set up times and quality of <br />The ability to scale th to handle future <br />service, regardless of the size of the <br />capacity, while maintaicient dispatch <br />system. <br />operations, <br />True end -to -end encryption capable <br />Assurance that sensitate communications will <br />from the subscriber to the console <br />r emain secure, from t in the field to the console <br />operator position, enhancing <br />dispatch operator <br />operational security <br />Improved bandwidth efficiencies reduce <br />Ongoing cost savings ta Ana. <br />transport costs. <br />1.3.1.2 Connection to ASTRO 25 System <br />Details on the connectivity between the MCC 7500 dispatch console and the ASTRO 25 system are <br />described below. <br />Dual Site Link <br />The MCC 7500 dispatch console site for City of Santa Ana is remote from the core site and is <br />provided with redundant site links to provide path diversity. The console site has two logical <br />connections to the Orange County Master Site, with each connection using a different core router. <br />Each console site gateway provides an interface that handles all of the IP Network Management <br />traffic between the MCC 7500 dispatch console center and Orange County ASTRO 25 system's core <br />site. <br />Orange County is responsible to provide two (2) T1 links to connect to the Santa Ana's dispatch <br />center based on the requirements below: <br />City of Santa Ana <br />MCC7500 P25 Dispatch Migration and Subscribers <br />02 April 2015 <br />Use or disclosure of this proposal Is subject <br />to the restrictions on the cover page. <br />0 Motorola Soludons Confldentlai Rastricted 55A -76 System Description 1 -5 <br />
