• One desktop microphone • Two heads ctjacks • Four desktop speakers • Logging recorder • Radio instant recall recorder • External telephone set • External paging encoder • Footswitch • Generic transnut audio input Some of the connectors listed above can be used to provide audio inputs and outputs for connecting other types of dispatch consoles to the Motorola radio system in conj unction with the Motorola MCC 7500 Dispatch APIs. The secure card provides encryption and decryption set-vices for the dispatch console. It is capable of supporting multiple, simultaneous encryption/decryption sessions using multiple algorithms and multiple secure keys. Personal Computer (PC) The dispatch console uses a customized Motorola - certified HP Z420 PC running the Microsoft Windows operating system, containing a Motorola - designed voice card and a Motorola- designed secure card. The PCs used in ASTRO 25 systems have a mini -tower fonn factor. The PCs are processed through Motorola factories in Schaumburg so that the application software, voice cards, and secure cards can be installed and tested to ensure they are operating properly. 1,4,2 Auxiliary Inputs and Outputs Included in the proposed dispatch solution is an Auxiliary Input /Output server. AUX 1/0 enables console operators to control and monitor externaL devices, such as doors and lights, from the console user interface. Multiple dispatch consoles anywhere in the network may monitor and control the same relay output and/or external inputs. Changes are indicated across all dispatch consoles simultaneously. Custom zable graphic icons are also used to provide a visual indication of both the function and state of external inputs. The contact closures and input buffers required to interface to these devices are housed in Remote Terminal Units (RTUs). These RTUs can be physically located close to where they are needed, at any console site or RF site. The dispatch consotes and RTUs communicate with each other across the radio system's IP transport network. Individual relay outputs can be configured so that they require a safety switch to be, pressed before they respond to any commands from the dispatch console user. Supported Aux 1/0 Configurations The following Aux 1/0 configurations are supported. Momentary Input This is an input where the user interface always shows the true state of the input. 02 April 2015 City of Santa Ana Use or disclosure of this proposal Is subJect MCC7500 P25 Dispatch Migration and Subscribers to the restrictions on the cover page. w System Description T -13 Motorola solutions Confidential Restricted 55A -84
