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.

1.1Contribution 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.

1.2Central Control Equipment

The Central Control Unit (CCU) forms the heart of the DCN system.The CCU can operate standalone 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.

1.3Simultaneous 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.

1.4Information 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.

1.5Application 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 trunkline 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 includes:

•Microphone management

•Synoptic Microphone control

•System installation

•Parliamentary voting

•Multivoting

•Delegate Database

•Simultaneous Interpretation

•Text/Status Display

•Attendance Registration

•ID-Card Encoding

•Message Distribution

•Intercom

•Video Display

•Automatic Camera Control

•DCN Start-up

•Multi-CCU

1.6Installation 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 multicore 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.

1.7Quick reference to DCN’s functions

Stand-alone System

A discussion system; delegates control their own microphone actions - without the need of a nonparticipating 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 delegate 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.

1.8DCN 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 with Voice activation

REFERENCE: For more information refer to the LBB 3570 software manual

1.8.2 Synoptic Microphone Control

Synoptic microphone control software provides a graphical solution using pictograms of microphone units. Run under Windows® the operator controls microphone units by simply pointing and clicking a mouse on the desired unit. Synoptic microphone control is icon based. It relies on the location of seats and uses pictograms that show icons with seat numbers or with names.

REFERENCE: For more information refer to the LBB 3571 software manual

1.8.3 Simultaneous Interpretation

Interpretation is the term used where the language of the ﬂoor speaker is interpreted by interpreters using interpreter desks into the languages of the other conference participants.

1.8.5 Voting

Parliamentary voting

Parliamentary voting allows delegates to vote ‘NO’,‘ABSTAIN’ or ‘YES’. It provides facilities for vote registration and display, with a choice of ‘OPEN’ (non-secret) and ‘CLOSED’ (secret) voting modes and selectable interim voting functions. Up to 9999 voting motions can be prepared in advance in a single script ﬁle and recalled instantly during a voting session (available with PC systems only). In PC based systems, editing facilities are also provided to simplify the preparation of updating script ﬁles. REFERENCE: For more information refer to the LBB 3575 software manual

Display facilities for video signals and graphic information such as seating plans and statistical voting representations can also be added to the system, using hall displays such as projection or direct view TV receivers, or giant-screen VidiWalls for larger audiences. Personal video displays can also be added in the form of LCD TV displays.

REFERENCE: For more information refer to the LBB 3583 software manual

1.8.9 Automatic Camera Control

Automatic camera control allows the speaker to be displayed on one or more video displays connected to a video control switcher. One or more dome cameras’ with a fast moving pan and tilt, zoom lens and a large number of pre set positions are automatically activated by the microphone control signals of the contribution units.

REFERENCE: For more information refer to the LBB 3588 software manual

1.8.10 Delegate Database software

Multi voting

Multi-voting software allows up to 6 voting methods to be selected,‘Parliamentary, ‘Audience response’, ‘Multiple choice’, Opinion poll, Rating and For/against. Vote related parameters can be speciﬁed for each individual voting method, such as: vote type, result display type, interim display, screen and print legends, hall display, vote weighting, roll call, voting LEDs and abstain options.The user is able to print the ﬁnal result and automatically export it to an MS-DOS ﬁle.

For more information refer to the LBB 3576 software manual. REFERENCE: For more information refer to the LBB 3576 software manual

1.8.6 Attendance Registration and Access Control

To register delegates to the DCN system, personnel ID-cards can be programmed and allocated to participating delegates.The card ensures that only authorised delegates are able to access the functions of a microphone unit, participate in a voting session and to make an intercom call.This facility is only applicable to units ﬁtted with an ID chip card reader.

REFERENCE: For more information refer to the LBB 3578 software manual

1.8.7 Intercom

An intercom handsets allows two-way vocal communication between conference participants, interpreters and operator.

REFERENCE: For more information refer to the LBB 3573 software manual

1.8.8 Text/Status Information Displays

Information displays range from hall displays for rooms of all sizes, down to personal displays for individual delegates.

Most of the displayed information is in the form of alphanumeric messages, shown on microphone units equipped with LC-displays, as well as on hall displays. A choice of solutions are available for hall display information like voting motions and results, delegates’ names and afﬁliations, request-to speak lists, personal messages, public announcements and multiple choice questions.

Delegate Database software is used to create names ﬁles of conference participants. It is used by several other DCN software modules to identify the conference participant and to control the delegates access to DCN functionality, i.e. microphone control, voting, use of intercom facilities. REFERENCE: For more information refer to the LBB 3580 software manual.

1.8.11 ID-Card Encoder software

Digital Congress Network \| Installation and Operating Manual \| Chapter 2 - Contribution Equipment	en \| 2-2

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.

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 backlit 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.

In portable systems, discussion units can be free-standing on a level surface - such as a table-top. In permanent installations, the units can be nut/bolt mounted using the 2 x M3 threaded holes under the unit. In such an installation, the units cable securing clamp can be removed from its cable entry and modiﬁed, allowing its 2 m cable to be neatly run through a hole directly under the table-top surface (see opposite). For cable clamp modiﬁcation, remove the cable clamp at the rear of the unit by unscrewing the clamps two securing screws (A) . Once removed, use a sharp cutting tool to remove the small insert (B) from its housing. Run the units cable through the cable run and secure it into the free cable entry using the removed insert (B) as shown in (D).

2.8Flush-mounted Contribution equipment

DCN’s broad range of ﬂush mounted units form the building blocks for creating individual system contribution units for use in custom built solutions.The ﬂush-mounted units are intended for use in ﬁxed installations, where portability is not required.The units can be neatly installed in to either tabletops or seat armrests.The range of ﬂush-mounted units available, provides all the functions and facilities offered by the table-top contribution units. For example a delegate unit can be created by combining a Multi-purpose connection unit LBB 3540/15 or Dual Audio Interface Unit LBB 3535/00. These units being the main components when creating ﬂush-mounted solutions in combination with

the following units:

FIG. 2-14 Orientation ﬂush-mounted units

All ﬂush-mounted units are available in standard sizes of 40 x 120 mm (1.57 x 4.72 in) with the exception of the ﬂush-mounted loudspeaker unit LBB 3538/00 which has a dimension of 80 x 120 mm (3.14 x 4.72 in) and the Delegate/chairman voting control panel LBB 3542/00 which has a dimension of 80 x 240 mm (3.14 x 9.44 in).The dimensions of the ﬂush-mounted units allow units to be neatly installed and positioned along side each other in either a portrait or landscape type conﬁguration.

Mounting

All DCN’s ﬂush-mounted units include a ‘click-to-ﬁt’ mechanism, enabling units to be secured into cutouts on table-tops or the armrest of seats in a landscape or portrait type format.

Two methods are used to mount the ﬂush-mounted units. Method 1 is used when mounting units into a metal surface and method 2, used when mounting units into a wooden surface.

Method 1 (mounting into a metal surface)

The ‘click-to-ﬁt’ mechanism available on all ﬂush mounting unit is used to secure the units into cutouts on table-tops or the armrests of seats etc. Additional screws are needed when mounting LBB 3537/xx Control Panel with microphone.The recommended method when installing the units, is to install them into a 2 mm (0.07 in) thick metal panel.The metal panel is used as the platform for securing the units.The panel needs to be cut-out according to the units template.

NOTE: Table top mounting is also possible for certain units with the Table-top housing LBB 3527/00. Refer to Chapter 2.24.

Method 2 (mounting into a wooden surface)

Units are secured by screws using the holes available on each unit. All units include drill guide holes located under the front cover of each ﬂush-mounted unit.The guide holes are used for guidance when drilling the units screw holes.

General

For cut-out templates and dimensions when physically installing the units refer to Chapter 13. “Mechanical data”.
