Through the switch, service technicians can access the system's configuration manager and service the equipment. Dual LAN switches have been provided to ensure dispatch functionality is not completely lost in the event of a LAN switch failure. Voice Encryption The MCC7500 provides true end -to -end encryption from the subscriber to the console operator position, enhancing operational security. This assures that sensitive, private communications will remain secure, from the user in the field to the console dispatch operator. AES and DES -XL encryption algorithms have been included in the proposal. Console Operations The MCC 7500 dispatch console is designed to provide mission - critical audio between the dispatch console and users in the field. It is optimized for real - time audio, prioritizing emergency calls over other traffic, minimizing voice queuing, and. transmitting calls in 450 milliseconds or less. Using robust error mitigation to maintain call quality even when the system is heavily loaded, the MCC 7500 dispatch console reduces communication errors that may force dispatch console operators to repeat their transmissions, City of Santa Ana NIGC7500 P25 Dispatch Migration and Subscribers Motorola Solutions Confidential Restricted 02 April 2015 Use or disclosure of this proposal is subject to the restrictions on the cover page.
