4. DCN Central Control
Equipment

4.1 Overview

Introduction
The DCN central conference control equipment is
based around the Central Control Unit (CCU). This
compact unit is at the heart of any DCN system, and
can control up to 240 contribution units such as dele-
gate- and chairman units, interpreter desks and audio
and multipurpose interface units. The CCU can func-
tion with or without a central operator using a PC.
In smaller systems where an operator is not essential,
the CCU is used as a stand-alone unit which provides
basic microphone operational modes, basic parliamen-
tary voting procedures and facilities for simultaneous
interpretation.

In larger systems necessitating an operator, a PC serves
as the interface between the operator and the DCN sys-
tem. A wide range of Windows-based application soft-
ware modules are available that are run on the PC to
provide comprehensive facilities for conference control
and management. When fitted with a DCN network
card, the PC can be connected to any point in the sys-
tem cabling. It is also possible to connect the PC direct-
ly to a CCU using an RS-232 port.
