1 Wireless network design
1.1 Introduction
The DCN Wireless has three parts: the wireless
network, the DCN and the optical network. This
chapter tells how to design the wireless network.
1.2 Limits
Limit 1: Control capacity
The maximum number of devices in the wireless
network that the central control unit can control is 150.
Limit 2: Coverage area
For a good operation of the wireless part, all wireless
discussion units need to be in range of the wireless
access point. The wireless access point has a typical
maximum coverage area of 30 m by 30 m. To
determine the exact coverage area the coverage test kit
can be used.
1.3 Frequency band
1.3.1 802.11g specification
The wireless network is based on the 802.11g
specification for WiFi technology. Devices that comply
to the 802.11g specification operate in frequency bands
between 2.4000 and 2.4835 GHz.
Note
Although the system operates on frequencies
which are license free world wide, you must be
aware of country specific limitations and follow
them.
1.3.2 Wireless computer networks
Wireless computer networks are also based on the
802.11g specification for WiFi technology. In the
wireless computer networks, 13 overlapping channels
are available (refer to figure 1.1).
Note
You can change the power value of the wireless
access point (refer to section 11.6.4).
Limit 3: Frequency
The wireless network must operate in a different
frequency band than adjacent wireless computer
networks (refer to section 1.3).
1.3.3 Carriers
In the wireless network of DCN Wireless, three
non-overlapping wireless carriers are available (refer to
figure 1.2).
1.3.4 Interference
The wireless network of DCN Wireless can cause
interference on wireless computer networks. You must
make sure the DCN wireless carrier does not overlap
the WLAN channel.
1.3.5 Example
Refer to figure 1.3. In the example, the WLAN channel
is 3. WLAN channel 3 overlaps DCN wireless carriers 0
and 1. Therefore, use DCN wireless carrier 2.

2DCN design
2.1 Introduction
The DCN Wireless has three parts: the wireless
network, the DCN and the optical network. This
chapter tells how to design the DCN.
2.2 Calculation tool
The calculation tool makes the planning and design of
the DCN easier. You can find the calculation tool on the
CD-ROM that is supplied with your system.
2.3 Concepts
2.3.1 Introduction
This section gives necessary data to understand the
limitations in section 2.4.
2.3.2 Trunk and tap-off sockets
The DCN uses two types of socket:
• DCN trunk sockets
Use the DCN trunk sockets to make a loop-through
in the trunk of the DCN.
• DCN tap-off sockets
Use the DCN tap-off sockets to make more branches
in the DCN. A DCN tap-off socket always
regenerates the digital DCN signal.
2.3.3 Cables
Many devices used in the DCN have a 2 m cable. If
necessary the extension cable (LBB4116) can extend the
device cables.
2.4 Limits
Make sure that these limits are not exceeded when you
design the DCN:
Limit 1: Control capacity
The maximum number of active devices that the central
control unit can control is 95:
• Max. 93x DCN-IDESK
• Max. 2x DCN-DDI:
• 1x with intercom handset
• 1x with ambient microphone
The number of passive devices is without limit (refer to
section 2.5).
Limit 2: Power capacity
• The maximum power that one DCN socket of the
central control unit can supply is 65 W.
• The total power that the DCN sockets of the central
control unit can supply is 130 W.
• The maximum power that one DCN socket of the
extension power supply can supply is 85 W
• The total power that the DCN sockets of the
extension power supply can supply is 255 W.
Refer to section 2.6.
Limit 3: Loop-throughs
The maximum number of loop-throughs in succession is
50. If there are more than 50 loop-throughs, the signal
must be regenerated with a trunk splitter (LBB4114/00).
Limit 4: Tap-off connections
The maximum number of tap-off connections in
succession between the central control unit and the last
tap-off in a branch is four. If there are more than four
tap-off connections in succession, the system does not
operate correctly.
Bosch Security Systems | 2007-02 | 9922 141 70691 en
Page 15
DCN Wireless | Installation and User Instructions | System Design and Planning en | 15
Limit 5: Cable lengths
Refer to section 2.7:
• With regenerative tap-offs, the maximum cable
length is 250 m from the central control unit to the
furthest device in any branch of the DCN.
• The maximum cable length from the central control
unit to the first regenerative tap-off is 100 m.
• The maximum length of the cable between
regenerative tap-offs is 100 m.
• Open-ended cables can cause an incorrect operation
of the system.
Note
The total cable length includes the 2 m long
device cables.
2.5 Control capacity
2.5.1 Active devices
Active devices are devices that can:
• Receive data from the central control unit.
• Transmit data to the central control unit.
Note
Active devices must have an address (refer to
section 12.2).
2.5.2 Passive devices
Passive devices can only receive data from the central
control unit.

2.6.4 Overload indication
Each DCN socket of the central control unit and
extension power supply has a red LED that comes on to
show that there is a power overload. An overload occurs
when:
• The necessary power for the devices is greater than
that is supplied.
• A short-circuit occurs.
When an overload occurs, the sockets are deactivated
and the connected devices do not operate. The socket
checks every 8 seconds (DCN-WCCU) or 30 seconds
(DCN-EPS) for power overloads.
2.6.5 Extension cables
Extension cables (LBB4116) have a direct effect on the
available power. The longer an extension cable, the less
power is available to drive the connected devices. You
must chose the length of the extension cables carefully
(refer to section 2.7.5).
2.7 Cable lengths
2.7.1 Maximum length
The cable length between the central control unit and
the furthest device from the central control unit must
not be more than 250 m. The cable length includes the
device cable and extension cables.
2.7.2 To first regenerative tap-off
The total cable length between the central control unit
and the first regenerative tap-off socket must not be
more than 100 m. This includes the device cables and
extension cables.
2.7.3 Between regenerative tap-offs
The total cable length between two regenerative tap-off
sockets must not be more than 100 m. This includes the
device cables and extension cables.
2.7.4 Open-ended DCN cables
‘Open-ended’ DCN cables are DCN cables of which the
socket is not connected to a device in the DCN.
‘Open-ended’ cables can cause an incorrect operation of
the system. You can ‘close’ the extension cable with a
termination plug (refer to the DCN Next Generation
Installation and User Instructions). When the
‘open-ended’ cable is connected to a termination plug,
the system operates correctly.

The necessary power from a DCN socket of the central
control unit and the extension power supply is affected
by:
• The type and number of connected devices.
• The lengths of the connected extension cables.
The power correction graph (refer to figure 2.3) corrects
the power level to compensate for the extension cables.
2.7.5.2 Calculation
To find the correction for each DCN socket of the
central control unit and the extension power supply
with the graph, you must first calculate:
• The total power consumption of the devices that are
connected to the socket. Refer to section 2.7.5.3.
• The length of the longest extension cable sequence.
Refer to section 2.7.5.4.
Page 18
DCN Wireless | Installation and User Instructions | System Design and Planning en | 18
2.7.5.3 Total power consumption
Do as follows:
1 Find the power consumption of each device from the
consumption table (refer to table 2.2).
2 Add together the power used by all the devices. The
result is the total power consumption of the devices
that are connected to the socket.
2.7.5.4 Length of the longest extension cable
sequence
Do as follows:
1 Add together the lengths of all extension cables in
the longest sequence.
For example, an extension cable of 20 m is connected
directly to a DCN socket of the central control unit. To
the extension cable, a trunk splitter is connected. To
each tap-off socket of the trunk splitter, an extension
cable is connected. One extension cable has a length of
10 m, the other extension cable has a length of 40 m.
The length of the longest extension cable sequence is, in
this example: 20 + 40 = 60 m.
2.7.5.5 Graph
The power correction graph (refer to figure 2.3) corrects
the power level to compensate for the extension cables.
Do as follows:
1 Find the total power consumption (refer to section
2.7.5.3) on the vertical axis (Y) of the power
correction graph. For example, 40 W.
2 Find the length of the longest extension cable
sequence (refer to section 2.7.5.4) on the horizontal
axis (X) of the power correction graph. For example,
60 m.
3 The intersection of both values gives the necessary
power from the socket. For example, 53 W.

3.5.4 Overload indication
Each optical network socket of the central control unit
has a red LED that comes on to show that there is a
power overload. An overload occurs when the
necessary power for the devices is greater than that
supplied. The sockets are deactivated and the devices
connected to the central control unit do not operate.
The socket checks every 8 seconds for power overloads.
Note
If only one of the optical network sockets has a
power overload, the two overload LEDs come
on.
3.6 Cabling
3.6.1 Introduction
Many devices in the optical network have two optical
network sockets that are interchangeable. You can use
the two optical network sockets to make a redundant
ring.
Note
The two optical network connectors are the
same.
figure 3.1: Optical network power supply
If more power is necessary, you must install external
power supplies in the optical network. The devices
below can connect to external power supplies:
• LBB4410/00 Network Splitter (refer to the DCN
Next Generation Installation and User Instructions).
• LBB4414/10 Fiber Interface (refer to the DCN Next
Generation Installation and User Instruction).
Bosch Security Systems | 2007-02 | 9922 141 70691 en
3.6.2 Definitions
The optical network uses two types of cable:
• POF
Plastic Optical Fiber.
• GOF
Glass Optical Fiber.
Page 24
DCN Wireless | Installation and User Instructions | System Design and Planning en | 24
3.6.3 Optical fiber length
Because of optical attenuation, the maximum length of
optical network cables (LBB4416) is 50 m. You can use
GOF and fiber interfaces to increase the distance
between devices to a maximum of 1500 m.
Note
If the distance between two devices is less than
100 m, use a network splitter between devices
to remove the use of fiber interfaces. Use only
the trunk sockets of the network splitter in this
case.
3.6.4 Cable couplers
You can use the LBB4419/00 Cable Couplers to
connect optical network cables to each other. A cable
coupler causes optical attenuation. Each cable coupler
decreases the maximum distance between two devices
in the optical network (normally 50 meters) with
20 meters.
3.6.5 Maximum cable length
The maximum cable length (LBB4416 and GOF) of the
optical network is dependent on:
• The number of nodes
• The number of LBB4414/10 Fiber Interfaces
Do as follows:
1 Find the number of nodes of each device from the
node value table (refer to table 3.1). Add together the
nodes of all devices.
2 With the value of step 1, use the graph (refer to
figure 3.2) to find the maximum cable length without
LBB4414/10 Fiber Interfaces.
3 Count the number of LBB4414/10 Fiber Interfaces.
Each fiber interface decreases the maximum cable
length from step 2 with 18 m.

3.7.4 Redundant cables
The example of the extended optical network (refer to
figure 3.6) has no redundant cable. If the cable between
the central control unit (DCN-WCCU) and the wireless
access point (DCN-WAP) breaks, the central control
unit cannot transmit data to the wireless access point. A
solution for this problem is to use redundant cable (refer
to figure 3.7 for an example).
3.7.3 Extended optical network
Refer to figure 3.6 for an example of an extended
optical network.

The example of the system without redundant cable
(refer to figure 3.6) has no connection between the
cobranet interface (LBB4404/00) and the central control
unit (DCN-WCCU). The example of the system with
redundant cable has a connection between the Cobranet
Interface and the central control unit. This connection
makes a ring. If a cable breaks, the optical network
continues to operate.
The maximum total power of all devices in the
redundant optical network is 65 W. If the optical
network is defective near the central control unit, the
other socket can supply power to all of the optical
network.

3.7.5 Tap-offs
The network splitter (LBB4410/00) lets you make
tap-offs (refer to figure 3.8 for an example). Tap-offs
cannot be redundant. If the cable between the network
splitter and the digital audio expander (PRS-4DEX4)
becomes defective, the digital audio expander has no
connection to the central control unit.

6 CobraNet
CobraNet is a standard for the transport of real-time
digital audio and control data through an Ethernet
network. A CobraNet network can transport a
maximum of 64 channels of 48 kHz, 20-bit audio
through a 100 Mbit link connection in each direction.
Many manufacturers of professional audio devices
support the CobraNet standard.
The DCN Wireless digital congress network can
connect to CobraNet networks with the LBB4404/00
Cobranet Interface. For example, you can use the
LBB4404/00 Cobranet Interface to:
• Benefit from Ethernet infrastructure
• Transport audio signals over large distances
Note
Refer to the DCN Next Generation Installation
and User Instructions for the LBB4404/00
Cobranet Interface.
PC data, for example data from the DCN Wireless
Open Interface can co-exist with CobraNet data on the
same Ethernet network when you use managed
Ethernet switches that are approved by Peak Audio.
Note
Refer to the website of Peak Audio
(www.peakaudio.com) for:
• More data about CobraNet networks.
• A list of approved Ethernet switches.

8 Device set-up
8.1 General
Caution
Do not put objects on top of devices. Objects
can fall through the airflow holes. A blockage of
the airflow holes can cause a risk of fire.
Caution
Do not put the devices near or above a radiator,
heat grill or in direct sunlight.
Caution
Do not cause vibration of the devices.
• Make sure that the area is clean.
• Make sure that the air is sufficiently cool.
• Make sure that there is sufficient lighting.
8.4 Ventilation
Keep a good airflow. Airflow holes are in the front, right
and left sides of all 19-inch devices (for example, the
central control unit and the audio expander).
• Put the devices on a hard and level surface.
• Put the central control unit at minimum distance of
0.10 m from walls to let sufficient air flow.
8.5 Cleaning
Caution
Do not use alcohol, ammonia or petroleum
solvents or abrasive cleaners to clean the
devices.
1 Disconnect the mains power supply from the
devices, if you want to clean the devices.
2 Use a soft cloth that is not fully moist with a weak
soap and water solution.
3 Let the device fully dry before you operate the
device again.
8.6 Storage
8.2 Cables
Use different cable ducts for the extension and mains
cables. Identify each cable with a label and divide
trunks to manageable geographic locations. In public
areas where people can touch or move above the
connectors and cables, use metal protection covers.
Refer to the applicable protection specification of the
protection covers.
8.3 Temperature
When devices are in a 19-inch rack, make sure there is
rack space between the devices to let sufficient air flow.
Forced airflow may be necessary to keep the
temperature of the devices below the maximum
temperature (refer to section 9.2). This extends the
lifetime of the devices.
Note
If the central control unit is stopped or
disconnected from the mains power supply for
more than 100 days, the values of all system
parameter are erased. This includes all the
values of the parameters of the interpreter desks
and the wireless access point. This does not
include the subscription list.
1 Disconnect the mains power supply from the
devices, if you do not use the devices for a long time.
2 Keep the devices in a clean and dry area with a
sufficient airflow.

8.7 Acoustic feedback
Acoustic feedback (‘howling’) occurs when the sound of
the loudspeakers or headphones in the system is sent to
the system again by activated microphones.
table 8.1: Acoustic feedback
Source Quick solution Structural solution
The acoustic feedback is caused by
the loudspeakers of the contribution
devices.
Decrease the volume level of the
system. For example, with the knob
on the front of the central control
unit (refer to section 10.6.3).
Do as follows:
1 Install a feedback suppressor
between audio input 2 and audio
output 2 of the central control
unit.
2 Set the audio routing mode of
the system to Insertion (refer to
section 12.6).
The acoustic feedback is caused by
an external public address system
that is connected to the DCN
Wireless digital congress network.
The acoustic feedback is caused by
the headphones that are connected
to the contribution devices.
Decrease the volume level of the
public address system or the DCN
Wireless digital congress network.
Tell the chairmen and the delegates
to decrease the volume level of their
headphones with their contribution
devices.
Install a feedback suppressor
between audio output 1 and the
input of the external public address
system.
Install and configure the
headphones level reduction of the
contribution devices. (Refer to the
section about the contribution
devices.)
