Audio processing, encryption, and <br />switching intelligence for dispatch are performed within <br />each software -based operator position, without <br />additional centralized electronics. <br />An MCC 7500 operator position consists of a computer, <br />a Voice Processing Module (VPM), one select speaker, <br />up to three unselect speakers, a desktop gooseneck <br />microphone and /or headset jack box with in-line PTT <br />amplifier and headset, and optional £ootswitch. <br />Voice Processing Module (VPM) <br />t a <br />Typical MCC 7500 Operator Position <br />Components <br />The VPM provides vocoding and audio processing services for the dispatch console. It connects to <br />the console site LAN switch and communicates with the dispatch console PC via Ethernet. Each <br />operator position includes a PC and a dedicated VPM. The VPM also provides connections for analog <br />devices to be connected to the digital console. <br />The VPM has connectors for the following devices: <br />02 April 2015 <br />City of Santa Ana Lisa or disclosure of this proposal Is subject <br />MCC1500 P25 Dispatch Migration and Subscribers to the restrictions on the cover page. <br />Q Motorola Solutions Confidential Restricted System Description 1 -12 <br />
