selection, private line selection, and repeater on/off. Additionally, the Enhanced CCGWs allow for recovery of MDC
1200 and digital signaling, such as unit ID, and emergency alarm, which is passed to the MCC 7500 dispatch operator
position(s).
2.3 MAKING CONSOLES EASY TO OPERATE
Motorola Solutions designed its MCC 7500 dispatch console to provide mission-critical audio between the dispatcher
and users in the field. Itis optimized for real-time audio, prioritizing emergency calls over other traffic, and minimizing
voice queuing. Using robust error mitigation to maintain call quality even when the system is heavily loaded, the MCC
7500 console reduces communication errors that may force dispatch console operators to repeat their
transmissions.
2.3.1 Customizable Dispatch Interface
The MCC 7500 console provides dispatch operators with a graphical user interface (GUI) that can be customized by
agency or by individual user to optimize user efficiency. Based on dispatcher preference, the MCC 7500 GUI can be
customized to show details of trunked and conventional RF channels on a per-channel basis. Busy dispatchers can
respond to a missed call by simply clicking on an entry in the Activity Log. The number of calls and call information
displayed in the Activity Log is customizable to suit the needs of the user. The status of auxiliary inputs and outputs
can be easily interpreted from the GUI with the use of familiar graphical icons, such as a door shown open or closed.
2.3.1.1 Elite Dispatch Graphical User interface
The MCC 7500 Elite Dispatch GUI is an enhanced version of Motorola Solutions’ Gold Elite Dispatch GUI. For existing
Gold Elite users, the GUI allows a smooth transition and minimal training for radio dispatch operators. For new users,
the graphical icons and customization options make the MCC 7500 console GUI easy tc learn and operate.
2.3.1.2 inbound Event Dispiay
For those users who prefer a call-based GUI, the MCC 7560 dispatch console supports the Inbound Event Display
(IED) GUI. The IED GUI displays incoming radio events in a queue format. The dispatch console user can manage and
respond to these events directly from the queue. Filtering and sorting features are available to allow the information
in the queue to be tailored to the needs of the dispatch console user. The console can be configured to operate in
“quiet mode” when using the IED GUI. This is well suited to customers who operate in a Request-To- Talk (RTT)
environment.
2.3.2 Standard Radio Transmission and Reception
A typical MCC 7500 console has a headset and two speakers, one for selected audic and the second for all remaining
unselected audio. Additional speakers can be added to the console, allowing dispatch operators to configure a
specific speaker for a set of designated audio sources. This simplifies multitasking between multiple audio sources,
allowing flexibility in the way the audio is presented to the dispatch operator.
2.3.2.1 Receiving Calls from the Field and Other Dispatch Operators
The MCC 7500 provides dispatch operators with great flexibility for how to hear calls from field radio users and other
dispatch operators. Each console dispatch operator can define his or her own audio reception profile by selecting a
single audio source, whether conventicnal or talkgroup, to be heard on a selected speaker or headset (“Single
Select”). The dispatcher can also define groups of radio resources that can all be heard on a selected speaker or
headset (“Multi-Select”).
2.3.2.2 Initiating Calls to the Field and Other Dispatch Operators
The dispatch operator has several different ways of initiating a call. In most circumstances, a “General Transmit” is
appropriate. With the general transmit, the dispatch operator selects a resource on the console and activates the
transmission through a footswitch, headset transmit button, or a microphone transmit button. If the dispatch operator
needs to quickly transmit on a resource that is not selected, the dispatcher uses the “Instant Transmit” function. An
