Extended Central Control Unit
• Sophisticated operator-controlled conference management
• Allows access to DCN software modules
• Controls up to 240 contribution units
• Back-up system in the event of PC failure
• Direct PC control facility
• Two RS-232 ports for serial data communication

This highly sophisticated central control unit is used in
combination with a personal computer to bring an
extra dimension to conference control. Via the PC the
user can access the extensive family of DCN software
modules, each with a specific function in controlling
and monitoring conferences. These modules greatly
expand the possibilities in conference management,
including advanced simultaneous interpretation and
microphone management, message generation and dis-
play, three kinds of voting, intercom, creating a delegate
database and attendance registration. In the event of PC
failure the Extended Central Control Unit will revert to
its default operation mode.

This mode is identical to that of the Basic Central
Control Unit, enabling the conference to proceed. The
PC is connected to the unit using a PC network card
(LBB 3510/00). Alternatively, the PC can directly con-
trol the CCU by connecting it to the CCU via an RS-
232 port. In this case, no network card is required.
Note: If the PC uses Windows 2000, Windows NT 4.0 or
XP Professional, it must be directly connected to the CCU.
For Windows 95/98 either direct control or control via the
network card is possible. However, direct PC control and
control by network card cannot simultaneously take place.
If direct PC control is used, additional operator equip-
ment is required to connect the Intercom Handset and
Cradle (LBB 3555/00), and headphones for monitoring
audio channels.
• Built-in power supply unit to supply both the Central Control
Unit and all externally connected DCN equipment. Up to 180
contribution units can be driven (with PCF of 1)
• Control facilities for controlling up to 240 contribution units.
This includes delegate- and chairman units, interpreter
desks, dual audio interface units and multi-purpose
connection units
• Control facilities for an unlimited number of distribution units
such as audio media interface units, data distribution boards
and electronic channel selector units
• Digital audio control and processing facilities for thirty Hi-Q
digital audio channels, which can be used for contribution,
interpretation and distribution purposes. The unit also pro-
vides four separate communication channels
• Automatic audio equalizer for delegate and chairman loud-
speakers
• Control and processing facilities for ten 64 kByte
