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.
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
Note
Although the system operates on frequencies
which are license free world wide, you must be
aware of country specific limitations and follow
them.
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.
1.3.2 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
1.3.3 Carriers
Note
You can change the power value of the wireless
In the wireless network of DCN Wireless, three
non-overlapping wireless carriers are available (refer to
figure 1.2).
Limit 3: Frequency
The wireless network must operate in a different
frequency band than adjacent wireless computer
networks (refer to section 1.3).
1.3.4 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
is 3. WLAN channel 3 overlaps DCN wireless carriers 0
and 1. Therefore, use DCN wireless carrier 2.

Limits
Make sure that these limits are not exceeded when you
design the DCN:
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.
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:

Concepts
2.3.1 Introduction
Limit 2: Power capacity
This section gives necessary data to understand the
limitations in section 2.4.
•
•
•
•
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.
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.
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).
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.
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.

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.
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
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.
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
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.
2.7.5 Power correction
2.7.5.1
Introduction
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.

result is the total power consumption of the devices
that are connected to the socket.
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.
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.
3 The intersection of both values gives the necessary
power from the socket. For example, 53 W.
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.

3.6.3 Optical fiber length
3.6.5 Maximum cable length
The maximum cable length (LBB4416 and GOF) of the
optical network is dependent on:
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.
•
•
The number of nodes
The number of LBB4414/10 Fiber Interfaces
Do as follows:
Note
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.
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 Count the number of LBB4414/10 Fiber Interfaces.
Each fiber interface decreases the maximum cable
length from step 2 with 18 m.
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.

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).
