DCN Data Brochure | Introduction |7Wired or wireless language distributionDCN offers a choice of language distribution systems.Language distribution can be carried out using theDCN system cabling, and languages are accessed andselected by means of channel selector units or delegateunits with built-in channel selection facilities. There isalso a wireless, digital infra-red system, Integrus, wherethe languages are distributed throughout the conferencevenue by infra-red transmitters and radiators, andaccessed by means of personal infra-red receivers withheadphones.Fully-automatic conference proceedingsThe basic CCU does not require operator control, andautomatically manages conference proceedings. It offersbasic microphone management, simultaneous interpretationand electronic voting facilities, as well as 15 Hi-Qdigital audio channels, ten data channels and four communicationchannels. This allows effective unsupervisedcontrol of even large, international conferences.Operator control via a PCThe extended CCU offers all the facilities of the basicmodel, but also allows operator control via a PC. Theuser can access the extensive family of DCN softwaremodules, each with a specific function in controllingand monitoring conferences.1.4 Central control equipmentThe Central Control Unit (CCU) forms the heart of thecongress management system. The CCU can operatestand-alone to provide automatic conference control,or be accessed by an operator via a PC when moreextensive management is required.All CCUs can control up to 240 contribution units,such as delegate and chairman units, interpreter desksand audio interface units. If more capacity is required,Multi-CCUs can be connected, each of which increasesthe system capacity by 240 contribution units. CCUscan power a number of contribution units. The maximumnumber depends on the type of CCU, and thetype of contributiion units used in the application.This includes advanced simultaneous interpretationand microphone management, message generation anddisplay, six kinds of voting, intercom, creating a delegatedatabase, attendance registration. In the event ofPC failure this CCU will revert to a default operationmode, identical to that of the basic CCU, thus enablingconference proceedings to continue.
