As part of ongoing enhancements to this solution, Motorola has joined and actively <br />participated in the P25 intomperab'ility committee to ensure continuously improving interoperabllity <br />with the radios of other P25 vendors. ASTRO 25 is also fully Common Air Interface (CAI) <br />compliant. <br />City of Santa Ana <br />MOC7500 P25 Dispatch Migration and Subscribers <br />Motorola can use multiple Santa Ana- furnished <br />interoperability radios to install, configure, and make <br />operational the necessary hardware and software to provide <br />two -way communications between the MCC 7500 dispatch <br />consoles and Mutual Aid channels. <br />As shown in Figure 1 -2, interoperable communications can <br />be provided through a dispatcher - initiated interface (patch) to <br />the Mutual Aid radios. The Motorola Conventional Channel <br />Gateway (CCGW) forms the bridge between the MCC 7500 <br />dispatch console on the ASTRO 25 radio network and the <br />02 April 2015 <br />Use or disclosure of this proposal Is subjeo[ <br />to the restrictions on the cover page. <br />Motorola Solutions Confidential Restricted 55A -74 System Description 1 -3 <br />
