System installation overview
It is advisable to participate in the DICENTIS Conference System training before you install,
configure, prepare, and operate a DICENTIS Conference System.
The DICENTIS Conference System is an IP based conference system which runs on an OMNEO
compatible Ethernet network. It is used for distributing and processing audio, video and data
signals.
The DICENTIS Conference System can be quickly and easily configured as a daisy‑chain
configuration or as a star configuration:
–
Daisy‑chain configuration: Uses dedicated cabling, consisting of CAT‑5e cables including
two additional power conductors (see Typical system setup, page 10).
–
Star configuration: Each DICENTIS device is connected with an individual standard
CAT‑5e cable. An Ethernet switch is also required for providing Power over Ethernet
(PoE).
Notice!
When Power over Ethernet is used, DICENTIS devices cannot be daisy‑chained. Please use
unshielded cable for the DICENTIS discussion devices.

An ARNI (Audio Routed Network Interface) is used to increase the number of DICENTIS
devices on a single subnet and to connect multiple DICENTIS system subnets. If more than
one subnet is required, two types of an ARNI must be used.
–
OMN-ARNIS (ARNI‑S OMNEO interface): The ARNI‑S is required for increasing the system
size above 100 DICENTIS devices. It supports up to 450 DICENTIS nodes in its subnet. It
also acts as a DHCP server in its subnet.
–
OMN-ARNI‑E (ARNI‑E OMNEO interface): The ARNI‑E is required for increasing the system
size above 450 DICENTIS nodes. It supports up to 450 DICENTIS nodes in its subnet. It
also acts as a DHCP server in its subnet. It can connect up to 40 subnets, each with an
ARNI‑S.
Defining subnets and subnet masks
A subnet is a logical, visible subdivision of an IP network. The number of DICENTIS devices
that can be in the same subnet depends on the subnet mask.
A standard class C subnet (255.255.255 or /24) can contain 254 IP addresses. Some
DICENTIS devices have 2 IP addresses. For this reason, Bosch advises to use 255.255.252.0
(or /22) as a subnet mask. This allows you to have 1018 IP addresses. The following table lists
the number of IP address per DICENTIS device in a DICENTIS Conference System.

Maximum number of DICENTIS devices in a string:
–
The max age timer should be set to 22 when RSTP is used for cable redundancy to
prevent a defective cable or powering switch from influencing the system.
–
Each time data hops from one switch to another, the age is increased by one. This timer
can be reached or exceeded, because a daisy chain can be used to loop through the
DICENTIS devices.
–
This timer (or restriction) cannot be reached when there is no cable redundancy. This is
because the power limitation will be reached before the max age restriction is reached.
–

The timer can be reached when:
–
you use cable redundancy,
–
the system is incorrectly wired.

System installation design and planning
Before you start to install system devices and connect system cabling, you should make a
system design and planning:
–
Familiarize yourself with the product and system capabilities.
–
Make a cable (connection) plan:
–
Calculate the system network cable length.
–
Calculate the system power consumption.
–
Calculate the required power capacity of the system.
Notice!
The DICENTIS Conference System uses the RSTP protocol when redundant cabling mode is
enabled. If the DICENTIS Conference System needs to be connected with the locally present
network, please consult the local IT department before continuing with the installation
design.
Notice!
Make sure that the cable lengths and power consumptions do not exceed the specifications.
Not doing so will result in malfunctioning at any moment of the DICENTIS Conference System
and products.
4.1
System capabilities
The capability of the DICENTIS Conference System and DICENTIS products depends on:
–
The lengths of the system network cables.
–
The number of connected devices.
–
The system power supply capacity.
Cable length
System network cables (DCNM‑CBxx-I) lengths (2, 5, 10 or 25 m) have a direct effect on the
available power supply capacity. The longer the system network cable, the less power supply
capacity is available to drive the connected devices. Therefore, choose the lengths of the
system network cables carefully.
Notice!
Custom network cables must never exceed the maximum Ethernet specification of 100m
(IEEE 802.3ab).
Keep your network hierarchy as flat as possible. This means having as few levels as possible.
It is recommended not to exceed 7 levels. See the following example: 1: 1st level = Root
switch, 2: 2 nd level = switch, 3: 3 rd level = switch.

DICENTIS
Power supply capacity
The total system network cable length and connected devices determine the required power
supply capacity. The power within the DICENTIS Conference System is supplied by:
–
The Audio processor and powering switch and the Powering switch, or
–
Off‑the‑shelf PoE Ethernet switches.
Calculation tool
The calculation tool can be used to calculate the total power capacity of the system. This
makes the design and planning of the DICENTIS Conference System easier. The calculation
tool uses the power consumption of the devices and the system network cable lengths to
calculate the needed system power supply capacity.
The calculation tool is on the DVD supplied with the Audio processor and powering switch and
is part of the DICENTIS software DCNM.iso file. The DCNM.iso file can be downloaded from

Switches
The following minimum requirements and recommendations apply to switches used in a
DICENTIS:
Requirement
Standard
Settings
Gbit Ethernet
IEEE802.3
Switch latency is maximally 10µSec with Gbit.
Valid for both copper and/or fiber ports.
Packet forwarding in
n.a.
If SW is responsible for packet switching, this would
HW per port
result in variable latency which is unacceptable.
>1.2Mpps
Quality of Service
DiffServ
With strict priority
To make sure PTP synchronization packets and
audio packets get priority over control packets.
OMNEO uses QoS on IP level to avoid
synchronization and audio problems on busy
networks. Although the system does work without
problems on relatively quiet networks (< 10%
network load) it is important to configure your
network switches correctly.
The used QoS is Differentiated Services or DiffServ,
which is part of the Type of Services field (ToS) in
the IP header. For more details on DiffServ & IP
header, see Wikipedia.
Warning: IEEE802.1p is also used for QoS, but is limited to layer 2. Since OMNEO uses IP
communication, this mechanism is not suitable, so make sure the used equipment uses
DiffServ QoS!
The table below gives an overview of the used DSCP values which need to be configured in

Disable EEE
IEEE 802.3az
Most implementations of EEE cause problems
because of implementation flaws. A good
implementation should work, but does not save
energy since the PTP synchronization avoids this.
Therefore, EEE must always be disabled.
Disable RSTP (when
Rapid Spanning Tree Protocol (RSTP) is required
no cable loops are

used)
no loops are created, RSTP needs to be disabled for
optimal operation. When enabled, it can cause slow
connections to the switch.
Possibility to create
n.a.
VLANS
VLAN separation is recommended instead of IGMP
snooping, because most switches are unable to
handle the multicast changes in the system. Filtering
multicast data may be necessary for some devices,
such as 100 Mb devices (Sony cameras, TVOne, AMX,
and others).
IGMPv3 IGMPv2
IGMPv3 or IGMPv2 snooping. To optimize bandwidth
snooping in
usage, IGMP snooping can be used. This is useful in
hardware
systems with >10 multicast streams, although not
absolutely required. Sufficient performance for
handling a large number of IGMP query responses,
depends on the number of (directly or indirectly)
connected devices to that switch. Hardware support
for IGMP snooping is strongly recommended.
Requirements when Standard
Settings

Calculation examples
The following example gives you an indication of the maximum load to each socket of an Audio
processor and powering switch or Powering switch.
–
Socket 2: 50 m cable + DCNM-MMD2 = 12 W1
–
Socket 3: 10 m cable + DCNM-MMD2 + 9x (2 m cable + DCNM-MMD2)
= (4.5 + 12) + 9x(1.19 + 12) = 135.21 W2.
–
Socket 4: 10 m cable + DCNM-D + 19x (2 m cable +DCNM-D)
= (4.5 + 3.1) + 19x(1.19 + 3.1) = 89.11 W2.
–
Socket 5: 10 m cable + DCNM-DE + 19x (2 m cable + DCNM-DE)
= (4.5 + 5) + 19x(1.19 + 5) = 127.11 W2.
4.3.2
For socket 2, the cable power consumption of the cable does not need to be counted if only one device is connected to this output.
The shortest redundant cable does not need to be counted.
Calculation using PoE switches
Select one or more PoE Ethernet switches to supply power to the DICENTIS devices. Each
DICENTIS device must be connected to an individual PoE enabled output of an Ethernet
switch.
Notice!
Some PoE Ethernet switches can only supply power to a limited number of ports. Others can
supply power to every port, but the total power the Ethernet switch can supply is limited.
Please consult the documentation of the PoE Ethernet switch used.
Notice!
Using PoE, DICENTIS devices cannot be daisy‑chained connected. Using PoE does not provide
redundant cabling.

Redundancy options
DICENTIS Conference Systems can be created with network redundancy. This ensures that the
system will continue to work if:
–
a network cable is defective or accidentally disconnected.
–
one of the components fails.
Different levels of redundancy can be created in the system depending on:
–
the type of unit used in the system (DCNM-APS / DCNM-PS or DCNM-APS2 / DCNM-PS2)
–
the number of redundant components used in the system.
–
the amount of redundant network cabling.
The following sections explain the redundancy options that can be used when designing your
DICENTIS Conference System. Each option can be combined in the DICENTIS Conference
System, providing you observe the redundant cabling limitations. Refer to:
–
Redundant cabling for DCNM‑APS/DCNM‑PS units, page 27.
–
Redundant cabling for DCNM-APS2/DCNM-PS2 units, page 28.
–
Redundant server PC, page 30.
Notice!
Rapid Spanning Tree Protocol (RSTP) must be enabled in the DICENTIS Conference System
for these redundancy options to work correctly.
Notice!
Follow these steps when setting up redundancy options for your system:
1.
First, set up your system without cable redundancy and RSTP configuration in the system
and DICENTIS.
2018.09 | V1.8 |
2.
Secondly, configure RSTP in the switches and DICENTIS.
3.
Thirdly, enable the cable loops.

Redundant cabling for DCNM‑APS/DCNM‑PS units
This section describes how to create redundant cabling for DCNM-APS or DCNM-PS units. The
maximum number of Ethernet devices in the loop (including the root switch) is 22. In a system
with no Ethernet switch(es), the APS is the root switch.
The total number of devices allowed in a loop depends on:
–
The type of device connected in the loop (for example, DCNM-MMD2 devices consume
more power than DCNM-DE devices).
–
The length of the loop (cable also consumes power).
The figure shows how to calculate the number of devices in the loop. The red line shows the
largest loop. The # sign shows the way the devices are counted.
In the example below up to 21 (22 - 1 = 21) discussion devices can be connected.

DCNM-CBCPLR Cable couplers
Cable couplers can be used:
–
to extend cables,
–
in a floor pod as break-out box,
–
as an interface between DICENTIS cable and “standard” CAT-5E cable combined with a
separate power cable,
–
to insert power locally to the participant devices,
–
to switch the system on by using two cable couplers and a switch.
Cable couplers are delivered in a box that contains 6 cable couplers. They can be used for all
types of DICENTIS cables.
5.5.1
Using a cable coupler to extend a cable
The DICENTIS Cable coupler can be used to extend cables, as it allows you to connect
DICENTIS Cable assemblies together. This way, it is possible to connect, for example, three 25
m (DCNM-CB25-I) cables together to form a 75 m cable.
Note:
–
The cable length is not allowed to exceed 100 m.
–
No more than 2 cable couplers can be used in one trunk.
