The MCC 7500 components are connected together and to the rest of the ASTRO 25 system on an IP network through
console site rauters and switches. The MCC 7500 dispatch console functions as an integrated component of the total
radio system, fully participating in system-level features such as end-to-end encryption and agency partitioning.
Since the network is IP-based, the system's interfaces and components can be distributed physically throughout the
network. Some of the available console components are identified below:
2.6.1 Operator Position Components
MCC 7500 dispatch operator positions connect directly to the radio system’s IP transport network without gateways
or interface boxes. Audio processing, encryption, and switching intelligence for dispatch are performed within each
software-based operator position, without additional centralized electronics.
« Headset Jack — Each dispatch console can support up to two headset jacks. A headset jack allows a
dispatch console user te use a headset while operating the dispatch console. Each headset can either be
connected to the console for supervisory applications or to a desk telephone. The equipment design
proposed includes two headset jack(s) per operator. The headset jack contains two volume controls to
adjust the level of received radio audio and the level of received telephone audio.
* Headset Base — The Headset Base comprises an audio amplifier, a push-to-talk switch and a long cord with
a PJ7 long frame connector at the end.
° Headset Top — The Headset Top comprises the earpiece(s), microphone, and a cable that connects to the
Headset Base.
* Gooseneck Microphone — The dispatch console supports a desktop microphone that controls the dispatch
console's transmit and monitor features through two buttons on its base. The microphone can be fastened
down or left loose and can be used alone or with a headset
¢ Footswitch — Each dispatch console can support a dual pedal footswitch. The footswitch controls the
general transmit and monitor functions.
2.6.2 Instant Recall Recorder Port (for Radio)
The instant recall recorder port (for radio) allows an instant recall recorder to be connected to a dispatch console.
The port provides an output containing the receive radio audio on the selected channels. Transmit audio of any type
(from either this dispatch console or a parallel dispatch console) as well as tones generated by the dispatch console
(emergency tones, callback tones, busy tones) are not included in the audio output. This recorded audio is retained
by the recording system for a short period (typically about 60 minutes) and is easily played back by the dispatch
console user.
2.6.2.1 Telephone/Headset Port
The telephone/headset port allows an external telephone set to be connected to the dispatch console. The dispatch
console’s headset can then be used to communicate on both the radio system and a telephone system (that is, a 911
system).
2.6.2.2 Personal Computer (PC)
The MCC 7500 dispatch console uses an off-the-shelf personal computer, running the Microsoft® Windows operating
system. The PC has a minitower form factor, comes with a keyboard and mouse, and supports a variety of monitors
including both touch and non-touch operation.
2.6.3 Conventional Channel Gateway Equipment
An Enhanced Conventional Channel Gateway (ECCGWs) provides the interface for analog and ASTRO 25
conventional channels to the ASTRO 25 radio system infrastructure. The ECCGW can support combinations of
