2. Hardware Overview
The C-6124 is a multi-line, multi-mode console designed specifically for growth in system requirements. The console
is based on a modular design utilizing multi-processor architecture for maximum flexibility. The system allows for
customization through software and expandability through common hardware.
The
User Interface Module (UIM)
is the central processor handling the user interface, common controls, touch screen
display, Selected speaker and VU meter, as well as keeping track of the activities of the Selected line.
The
Switch Bus Module (SBM)
accepts up to six plug-in individual line cards via common audio and data busses. Up
to three SBM’s can be added to the C-6124.
The
End Bus Module (EBM)
houses the Unselect audio amp and the last six line card slots.
2.1
User Interface Module (UIM)
The UIM consists of the following eight sub-assemblies: power supply, VU meter PCB, crosspatch switch PCB, voice
delay PCB, UIM digital and analog PCB’s, LCD display and touch screen. The central processor is mounted on the
UIM digital PCB. It monitors and controls the activities of the console with respect to the console operator. The
touch screen display is constantly being monitored for activity from the operator while providing instructional
information and feedback. The UIM digital PCB monitors the data bus for line Select while providing PTT, telephone
dialing, and handset hook data to the line cards. All programming functions are accessed through the data bus from
information entered on the touch screen display when in programming mode. All audio is processed on the UIM
analog PCB, this includes TX (microphone), Select and Unselect Speaker and Crosspatch busses. TX audio is
processed and routed to the audio bus while the receiv e audio is routed to the appropriate speaker power amplifier or
the handset/headset earpiece. The earpiece level is internally adjusted to a comfortable listening level and is not
affected by the speaker volume control. The microphone sensitivity as well as the display contrast may also be
adjusted internally.
2.2
Switch Bus Module (SBM)
The SBM is mounted between the UIM and EBM and is interfaced to the UIM analog PCB through a ribbon cable
connecting the microphone audio, Select audio, Unselect audio, crosspatch and the data busses together. This entire
bus interface is then branched out to the connectors to which the individual line cards are installed. When a line card
is installed onto the SBM, the four switches, associated indicators and the Unselect volume control for that line
position electrically become part of the line card and are under full control of the card's software. The Unselect
The console consists of three assemblies.
