1. Introduction
Digital Congress Network
World’s first digital congress interpretation system,
upgraded for even higher performance
The Bosch DCN Next Generation Interpretation System
brings the benefits of innovative digital technology to interpretation systems. Digital signal processing and transmission
via a simple network system greatly improves audio quality
and simplifies operation and installation.
DCN Next Generation Interpretation System provides flexible management of facilities from small gatherings with only
a few languages to large assemblies with as many as 32 languages. The system offers versatility, high audio quality with
20 kHz audio bandwidth, and data transmission security
while providing complete control over conference proceedings.
Modular system approach
By simply daisy chaining the modular DCN Next
Generation Interpreter and language channel selector units,
any configuration can be put together. The modular structure of the system means any level of conferencing can be
created without difficulty. Systems can be easily expanded by
adding components and PC control with software modules.
Range of equipment
The range of DCN Next Generation Interpretation System
products include central control units, simultaneous interpretation and language distribution equipment, applicationspecific software modules, information provisions, and
installation equipment. This can be complemented by
external equipment such as PCs, video screens, booster
amplifiers, and loudspeakers, all of which are fully compatible and easily integrated into the DCN Next Generation
Interpretation System.

Audio Expanders
A new addition to the DCN Next Generation
Interpretation System is the ability to connect audio
expanders. This makes it possible to extract and insert
audio into the system. These audio expanders are connected to the CCU via the optical network cable.
The audio expander can be used to record and distribute
the floor signal and available languages from the system.
A special function of the audio expander enables the
coupling of small systems with only few languages into
a large system with as many as 31 languages.

Excellent audio quality
The result of this advanced digital technology is excellent
audio performance with no loss in signal quality or level
during transmission. Each unit receives a consistently
high quality audio signal. This significantly enhances the
intelligibility of speech. DCN Next Generation virtually
eliminates the problems usually associated with conventional systems, such as background noise, interference,
distortion, and cross talk.
Installation is further simplified and speeded up by the
use of splitters and ready-made cables with sturdy connectors, allowing easy insertion of equipment at any
point in the system cabling. These easy-to-connect accessories are used for both fixed and portable installations,
making DCN Next Generation a versatile system that can
be installed quickly and efficiently in any situation or
environment.
Reduced installation costs
Fast, cost-saving installation is an important benefit of
DCN Next Generation digital technology. Thin, flexible,
twin-coaxial cable and twin-optical fiber carry all the
system’s digital signals. This eliminates the need for the
costly and vulnerable multi-core cables used in conventional analogue installations. The twin-coaxial cable and
twin-optical fiber can easily be run through existing
ducting and cable conduits. These can simultaneously
carry up to 32 high-quality contribution channels and
32 high-quality distribution channels.
Simultaneous interpretation and language
distribution
The DCN Next Generation system offers comprehensive
facilities for simultaneous interpretation and distribution
of interpretations to conference participants, meeting
the stringent demands of international, multi-lingual
conferences and congresses.
Simplified wiring
Gone are the days of complex wiring through bulky
trunking. The cables used for DCN Next Generation signal transmission are a sturdy twin-coax cable moulded
with a 6-pole connector and a twin-fiber terminated with
easily mounted connectors.
Both cables are used to transport signals to units
throughout the system and can be tapped at any desired
point to connect extra equipment, thus providing a
branched-tree topology. Future extensions to the system
capacity, such as adding extra units or increasing the
number of language channels, will not require alterations
to the existing system cabling. Power is also supplied to all
units via two wires in the same cable, a major advantage.
The system enables direct or auto-relay interpretation
modes for less well-known languages. Each interpreter
desk has an output for the normal (primary) language
and another for alternative languages.
6 | Introduction | DCN Next Generation Interpretation System Data Brochure
Up to 31 different languages
The DCN Next Generation interpreter desk can accommodate up to 31 different language channels, plus the
original floor language, all with an audio-bandwidth of
20 kHz.
There is also the Integrus wireless, infra-red system that
distributes languages throughout the conference venue
using infra-red transmitters and radiators. Access is by
means of personal infra-red receivers with headphones.
Integrus can be easily connected to the DCN Next
Generation Interpretation System to distribute all 32
languages with unique Bosch IR-Digital technology. This
technology also conforms to IEC 61603, Part 7. Bosch IR
Digital technology ensures maximum sound quality with
a signal-to-noise ratio of 80dB. The Integrus system also
incorporates a special operation mode to couple rooms.
This means that multiple systems, located in other rooms,
can provide exactly the same languages.
For more information about Integrus see the Integrus
Data brochure.
A maximum of six desks can be installed per interpreter
booth. It can be used stand-alone or as part of a comprehensive system. When used stand-alone, the built-in
microprocessor is manually programmed to allocate language channels, channel routing, and interlocks. In operator-controlled systems, the desk is used in combination
with DCN Next Generation dedicated software (the
Simultaneous Interpretation module LBB 4172) to form a
completely integrated interpretation network.
Wired or wireless language distribution
DCN Next Generation offers a choice of language distribution systems. Language distribution can be carried out
using the DCN Next Generation system cabling, with languages accessed and selected by means of channel selector
units.
Central control equipment
The Central Control Unit (CCU) forms the heart of the
Congress Management System. The CCU can operate
stand-alone to provide automatic control, or accessed by
an operator via a PC when more extensive management is
required.
Each CCU can control up to 6 x 31 interpreter units and
an unlimited number of language channel selectors.
Fully-automatic Interpretation Proceedings
The CCU does not require operator control and automatically manages proceedings. This allows effective,
unsupervised control of even very large, international
conferences.
Operator control via a PC
The CCU allows operator control via a PC. The user can
access the DCN Next Generation software modules, each
with their specific control and monitoring functions.
In the event of PC failure, the CCU reverts to a default
operation enabling proceedings to continue without
interruption.

5.1 LBB 4190/00 DCN NG Startup Software
The Startup screen is active whenever DCN NG software
modules are used for controlling and monitoring. This
module is different from all other DCN NG software
modules because it is primarily used as a platform from
which the other modules are selected.
However, this is only one aspect of Startup. The following
can also be carried out:
Features and benefits
• Setting master volume levels
• Opening, closing and deleting Installation File
• Configuring the Startup program to automatically load selected DCN modules
• Accessing, acknowledging and printing error messages
• On-screen help facility
When Startup is loaded, it presents the user with a desktop window that is the DCN NG opening screen. The
other DCN NG modules are represented by icons in this
opening screen, and can be activated simply by clicking
5.2 LBB 4185/00 DCN NG System Installation
The System Installation software is a powerful and effective tool for installers and system operators when
installing and setting up the DCN NG system. System
installation, set-up and functions are brought entirely
under PC control through its easy-to-use, Windows-based
software.
Features and benefits
• Single-point control of system installation
• Facilities for assigning functions to audio channels
• In-conference warning message when installation configuration changes
• On-screen help facility
The DCN NG System Installation software provides – in
an easy yet methodical way – to specify the number of
audio channels dedicated to interpretation and intercom
facilities.
on them. Startup also has a facility which allows other
DCN NG modules to be loaded automatically.
This saves having to manually select modules that are
used virtually every time the DCN NG system is in
operation. The user can specify any combination of
modules for automatic Startup.

5.3 LBB 4172/00 DCN NG Simultaneous Interpretation
Simultaneous interpretation is an essential component
in the international congress venues of today. The
Simultaneous Interpretation program supports the
preparation of simultaneous interpretation facilities and
the monitoring of interpreter activities during a conference. It can accommodate 31 interpreter booths, each
with up to 6 interpreter desks.
Features and benefits
• Can accommodate 186 interpreter desks
• Online monitoring of interpretation activities
• Facilitates normal and relay interpretations
• Microphone mode options
• Specifying a language for each of the system interpretation
channels
• Determining the microphone interlock mode
• Online monitoring of interpreter activities during a conference
• Onscreen help facility
The main window has two display modes, both rich in
graphics for easy assimilation of information. One gives a
channel-oriented overview of system status, such as
which language is present on that channel, the mnemonic
for that language, on which language the interpretation is
based, and the number of the desk and booth generating
that language. The other display mode gives the same
information in a different form, providing an overview of
the status of each desk in each booth. This includes booth
and desk status (active or non-active), and the language
in and out of each active desk.
In addition, the software enables the operator to establish
microphone interlocks, between booths and within
booths, with or without using an override facility. In
interlock mode, the active microphone must first be
turned off before any other microphones can become
active. In override mode, any microphone can automatically override the current active microphone and become
active.
The interpreter system settings are stored in an interpreter configuration file. There are a number of options
available to the user for working with these files, all of
which are standard DCN NG file options. These consist
of opening, creating and saving files under a new name.
A print function enables a hard copy printout of desk
and channel language assignment – ideal for use as a
reference to current system settings.

Examples
• The total DCN cable length (using standard
LBB 4116/xx cable) between the central control unit
and the last unit in any branch of the system must not
exceed 250 m (820 ft 2 in). This includes all extension
cables and the 2 m (78.74 in) long cable attached to
each system unit
• The total number of units from the central control
LBB 4100/00 unit to the first regenerative tap-off (i.e.,
from Trunk Cable Splitter LBB 4114/00 or Extension
Power Supply Unit LBB 4106/00) must not exceed
50 pieces (100 m [328 ft 1 in])
• The total length of the extension cable between regenerative tap-offs outputs must not exceed 100 m (328 ft
1 in)
• The maximum distance between units is normally
160 cm (62.99 in). This distance can be increased by
using the LBB 4116/xx Extension Cable
• The total Plastic Optical Fiber (POF) length (using
standard LBB 4416/xx cable) between two units is 50 m.
When more than 50 and less than 1500 meter is
required, fiber interfaces LBB 4414/00 and Glass
Optical Fiber (GOF) must be used. Only multimode
GOF with a maximum attenuation of 2 dB/km and a
wavelength of 1300 and terminated with SC connectors
is supported.
It is also possible to increase the 50 m by inserting a
network splitter LBB 4410/00 every 50 m or less.
• The maximum length of all optical fibers together (POF
& GOF) depends on the number of nodes in the system. The graph below shows the relation between the
number of nodes and the fiber lengths.
The examples given below of the LBB 4100/00,
LBB 4106/00 show the following:
• Maximum number of units that can be connected to a
single output
• Maximum number of units that can be connected to all
outputs
• Maximum DCN cable length from an output to the last
unit

In these examples, the following annotations are used:
ID = Interpreter desks
CS = Channel selectors
AEX =Audio Expander
It can be seen by the maximum number given for each
type of unit that a Channel Selector requires less power
than a Interpreter desk, and therefore more Channel
Selectors can be connected to central control equipment.
Interpreter desks require more power than the Channel
Selectors.
