Chapter 1. Introduction Digital
Congress Network
(DCN)
The BOSCH Digital Network System (DCN) provides flexible control facilities for all types of
conferences from small discussion groups to international, multi-lingual congresses with hundreds of
delegates. Facilities range from basic microphone management, to delegate identification and
registration, electronic voting, information distribution and display, up to extensive simultaneous
interpretations and automatic camera control. A single operator using a computer with DCN’s
application software can control even the largest of congresses. Systems can be expanded by adding
more contribution equipment and introducing PC control with DCN’s application software.
The full range of DCN equipment includes:
1. Contribution equipment
2. Central control equipment
3. Simultaneous interpretation and language distribution equipment
4. Information display equipment
5. Application software packages
6. Installation equipment
DCN equipment is also complemented by external equipment such as video and character displays,
TV cameras, personal computers, monitors, PA amplifiers, loudspeakers and printers all of which are
fully compatible and easily integrated into the DCN system.
1.1 Contribution equipment
Contribution equipment describes the units which participants use to contribute to a conference.
Depending on the type of contribution unit, delegates can access the DCN’s wide range of facilities to
listen, speak, register a request-to-speak, receive screen messages, communicate with other delegates
via an intercom and to participate in electronic voting sessions. On insertion of an ID-card dedicated
software is required giving much more facilities.
Contribution units can be used free-standing on a table-top, or flush-mounted in desks, seat backs or
armrests. Other microphone types such as lavalier and hand-held are also available, allowing
contribution from non seated participants such as a guest speaker for example.
1.2 Central Control Equipment
The Central Control Unit (CCU) forms the heart of the DCN system.The CCU can operate stand-
alone to provide automatic conference control, or it can be accessed by an operator via a personal
computer (PC) when more extensive management control is required.
All CCU’s can control up to 240 contribution units. If more capacity is required, slave CCU’s can be
connected, each of which increases the system capacity by 240 contribution units. A maximum of 16
slave CCU’s can be connected to a system. Other extension units include an Extension Power Supply
unit and an Audio Media Interface unit which extend the systems power handling capacity.
The CCU offers basic microphone management, simultaneous interpretation and electronic voting
facilities, as well as digital audio channels, data channels and communication channels.This allows
effective unsupervised control of even large or international conferences. The extended CCU offers
all the facilities of the basic CCU, but allows operator control via a personal computer (PC).The
operator can access the wide range of DCN application software packages, each with a specific
function in controlling and monitoring conferences.This includes advanced simultaneous
interpretation and microphone management, message generation and display, voting procedures,
intercom, creating a delegate data base, attendance registration, audio processing and automatic
camera control.

Sim ltaneo s Interpretation and Lang age Distrib tion Eq ipment
1.3 Simultaneous Interpretation and Language
Distribution Equipment
Interpretation.
Using the same trunk-line cabling DCN’s interpreter desks can easily be integrated into existing
systems, offering comprehensive facilities for simultaneous interpretation.The desk can accommodate
up to 15 different language channels, plus the original floor language. A maximum of six desks can be
installed per interpreter booth.They can be used stand-alone or as part of a more comprehensive
system.When used stand-alone, the units built-in microprocessor is manually programmed to allocate
language channels, channel routing and interlocks. In PC operator-controlled systems, the desk is used
in combination with DCN dedicated software, and other interpreter desks (if required) to form a
completely integrated interpretation network. An in-built facility enables direct or auto-relay
interpretation to cater for less well known languages. Each desk has two output channels, one for the
normal interpretation and one for second or auto-relay translation.
Language Distribution
Distribution of languages to individual delegates can be by wired or wireless language distribution
systems. A wired language distribution system uses delegate contribution units that include a language
channel selector, or dedicated language channel selector units. A wireless language distribution system
uses the Infra-red transmission technique.
1.4 Information display equipment
The DCN system can distribute information to conference participants quickly and efficiently to suit
all requirements. A wide range of displays are supported from simple LCD personal screens to video
equipment for venue broadcasting.
The chairman unit, interpreter desk and one type of the delegate unit is equipped with a graphic
(chairman, delegate) or alphanumeric (interpreter) LC-display which displays delegate information,
voting results and operational procedures, public and personal messages, microphone status and
multi-lingual user instructions.
Hall displays can quickly display conference information to a large number of conference participants.
Numeric, alphanumeric or geographical displays are available, to display voting results. TV receivers
and Video Displays allow high quality display of any live or recorded material, computer-generated
graphics, text, and information generated by DCN software.
1.5 Application software packages
A comprehensive range of software packages is available for use with centrally controlled PC-systems.
These packages run under Microsoft® Windows® integrate conference preparation management
and control into this versatile graphical computer environment. Any combination of packages can be
down-loaded according to specific system requirements. DCN software packages are generally used
in larger scale systems where operator control is required.
The PC running the software is connected to the DCN system and therefore has direct
communication links with contribution, interpretation and control equipment via the systems trunk-
line data bus or the CCU’s serial communication port.Therefore all aspects of conference
management can be brought to a single point of control, Leading to increased ease of use, efficiency
and data distribution.
The range of DCN software packages include
s:
• Microphone management
• Synoptic Microphone control
• System installation
• Parliamentary voting
• Multi- voting
• Delegate Database
• Simultaneous Interpretation
• Text/Status Display
• Attendance Registration

Installation eq ipment.
1.6 Installation equipment.
Fast cost-saving installation is an important benefit of the DCN’s digital technology. A thin twin-coaxial
cable carries all the system’s digital signals, eliminating the need for the costly and vulnerable multi-
core cables used in conventional analogue installations.The same cable is used to transport the signals
to all delegates’ microphone units throughout the system and can be ‘tapped off ’ at any desired point
to connect the microphone units or any system unit associated with the DCN system. Later capacity
extensions - for example to add extra microphone units does not demand changes to the system
cabling. All that is needed is to connect the required DCN system units or branches to the installed
cabling.Trunk-line splitters and extension cable assemblies are available to simplify installations in
difficult working areas.
DCN’s System Philosophy.
The DCN introduces the latest digital technology, bringing far reaching benefits to the audio quality, as
well as to promote the addition of a wide range of external peripheral equipment to conference
systems.
FIG 1-1 shows the concept of DCN’s digital communication techniques.The Network cabling forms
the system infrastructure providing the communication media between the Microprocessor
controlled Central Control and all units connected to it. Using standard plugs and connectors
throughout the system means that units can be connected to the Network at any convenient points,
making installation quick and simple.
Communication through the Network cabling and all units connected to it, is done using three
dedicated digital communication IC’s, ACN
1 , ACN 2 and ACN 3. Units that include an ACN 1
microprocessor - such as the delegate unit, chairman unit and interpreter desk - communicate to the
Central Control Unit, via the units ACN 2 microprocessor on a send and receive basis (active or
passive). Units that include an ACN 3 microprocessor - such as the Channel selector units - receive
information on a receive basis only, such units are known as passive units.
Praedic
The integrated circuit (IC), PRAEDIC (Professional Audio Encoder Decoder Integrated Circuit)
combines a built-in amplifier with both Analogue-to-Digital and Digital-to-Analogue convertors.The
IC converts analogue signals (such as from a delegates’ microphone) and digitizes them for
distribution throughout the DCN network cabling. In return the digitize signal is then fed back to the
Praedic and converted back to an analogue signal for distribution throughout the DCN units - such as
delegate loudspeakers and headphones.

Q ick reference to DCN’s f nctions
1.7 Quick reference to DCN’s functions
Stand-alone System
A discussion system; delegates control their own microphone actions - without the need of a non-
participating operator. Discussion systems cater for smaller groups, although the number of delegates
can be extended to the total capacity of the DCN system. A discussion system therefore is ideal for
small meeting halls, boardrooms, and hotels etc. where clear and concise speech intelligibility through
sound amplification is required.
PC Controlled System
Delegates’ microphone actions are controlled by a none participating operator using a personal
computer.
Microphone Management
Method by which delegates/operator control the microphone units. Microphone Management
control therefore is needed in order to conduct civilised and disciplined discussions/conferences.
The DCN system has its own built-in standard microphone control functions.These functions are
usually sufficient for use in discussion groups using a stand-alone system. In conference systems
however a central PC operator has extended microphone management capabilities when using
DCN’s dedicated microphone management software.
Microphone Management Operation Modes:
OPEN (AUTO)
The OPEN mode allows up to 1, 2 or 4 delegates (Active Micros) to control the on/off state of
their own microphones unit simultaneously without the use of operator intervention.When more
than the number of Active Micros has been reached, delegates requesting to speak join a request-
to-speak list.
OVERRIDE (First-In-First-Out)
The Override mode allows up to 1, 2 or 4 delegates to speak on a FIRST-IN FIRST-OUT basis i.e
Override.With the override mode, their is no request-to-speak list, only the pre-selected number
of Active Micro’s may be switched on simultaneously.This means that if another delegate should
switch on his microphone unit, the microphone of the first delegate having joined the group will
be switched off, allowing the latest delegate to join in the discussion.
VOICE ACTIVATION
The ‘Voice’ activation mode is an automatic method for activating the microphones of the dele-
gate and chairman units by voice.The maximum number of voice activated units available for
selection in a stand-alone system is 2 or 4.This mode of operation is intended for free discussion
amongst participating delegates. For enhanced operation an additional Public Address system is
highly recommended.
1.8 DCN Software packages
1.8.1 Microphone Management software
Microphone management software provides a text-based solution (delegates’ names) for managing
delegates’ microphones. Run under Windows® the operator controls the delegates’ microphone
operations through menus.
The Microphone Management software offers five modes of microphone control:
• Operator with *Request-to-speak list (MANUAL)
• Operator with *Request and **Response list
• Delegate with *Request-to-speak list (OPEN)
• Delegate control with override (of other delegates’ microphones)
*A Request-to-speak list is a list of delegates waiting to speak.To join the list delegates first press
their microphone keys. If the maximum number of delegates are already speaking the delegates
then joins the list. The number of delegates allowed to speak at the same time is set to 1,2,3, or
4.
** A response list is a list of delegates that need to react immediately to a current speaker.
Response requests are positioned at the top of the request list.
• Delegate withVoice activation

CONTRIBUTION EQUIPMENT
2.1.2 Delegate unit
For use by delegates to actively participate in discussion/conference proceedings - ranging from small
discussion groups to multi-national conferences. Its basic functions allow delegates to speak, listen to
other participants, and to participate in voting sessions (conference units only) using the units voting
keys .
2.1.3 Chairman unit
For use by a chairman, the chairmans unit is similar to the delegate unit but includes a ‘priority button’.
This button when pressed temporarily mutes or permanently cancels all other microphone users. An
optional chime tone is available when the priority button is used. A system may have one or more
chairman units; for use by assigned delegates, privileged speakers or VIP’s etc. In permanent mode, all
delegates waiting to speak are also removed from the request-list. Chairman unit LBB 3547/00 has
five soft-keys that enable the chairman to control, initiate, and to participate in voting sessions, as well
as to cancel all delegates’ microphones and requests-to-speak.
FIG. 2-1 Table-top contribution units
2.1.4 ‘Microphone Only’ Function
A microphone ‘only’ function is for use by Podium and mobile floor speakers, or in installations where
no delegate units are used. DCNs range of microphones can be connected to a Dual Audio Interface
unit or a Multi-purpose connection unit.The Dual Audio Interface unit LBB 3535/00 can serve two
delegate positions.
2.1.5 Interpreter desk
For use in bi/multi-lingual discussions/conferences, the interpreter desks can handle up to 15 different
language channels in addition to the floor language. Up to six interpreter desks can be installed per
booth. Its design provides for efficient operation, and preselection of the incoming language. A back-
lit alphanumeric display shows the selected language in combination with a ‘quality indication’ (direct
or indirect interpretation). An ‘auto-relay’ facility enables interpreters to interpret from unfamiliar
languages, where the desk automatically transmits the relay language to all other interpreter desks for
onward interpretation.
