3 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.

3.2 System extension
The DICENTIS Conference System is scalable from small to medium to large. This section
describes what a small, medium and large system is and what the requirements are for these
systems:
A small DICENTIS Conference System (see Typical system setup, page 10) consists of:
– up to 100 DICENTIS devices.
– all DICENTIS devices in 1 subnet.
– 1 DICENTIS Audio processor and powering switch for the audio processing.
– 1 Server PC which hosts the DICENTIS services.
A medium DICENTIS Conference System consists of:
– up to 450 DICENTIS nodes.
Refer to table X about the node count of DICENTIS equipment.
– all DICENTIS devices in 1 subnet.
– 1 DICENTIS Audio processor and powering switch for the audio processing.
– 1 Server PC which hosts the DICENTIS services.
– 1 ARNI-Standard to increase the size of the system.
A large DICENTIS Conference System consists of:
– up to 750 DICENTIS devices.
– multiple subnets connected by use of a router/L3 switch.
– Each subnet can have up to 450 DICENTIS nodes.
Refer to the following table for the node count of DICENTIS equipment.
– The first subnet has:
- 1 DICENTIS Audio processor and powering switch for the audio processing.
- 1 Server PC which hosts the DICENTIS services.
- 1 ARNI-Enterprise to increase the size of the system.
– All other subnets have 1 ARNI-Standard to increase the size of the system.
Note: There is no DICENTIS Audio processor and powering switch in the other
subnets.

ARNI‑S OMNEO interface 0
Tab.3.1: Nodes count of DICENTIS equipment
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.

DICENTIS System installation design and planning | en 17
Bosch Security Systems B.V. Hardware Installation Manual 2018.09 | V1.8 |
4 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.

3 3 3 3
Figure4.1: Example: Switch-levels

18 en | System installation design and planning DICENTIS
2018.09 | V1.8 | Hardware Installation Manual Bosch Security Systems B.V.
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
the Bosch website at: https://licensing.boschsecurity.com/software

Bosch Security Systems B.V. Hardware Installation Manual 2018.09 | V1.8 |
4.2 Hardware requirements
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
HW per port
>1.2Mpps
n.a. If SW is responsible for packet switching, this would
result in variable latency which is unacceptable.
Quality of Service
With strict priority
DiffServ 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
the switch:
Data DSCP dec DSCP hex DSCP Label TOS byte
(hex)
Switch
Priority
queue
PTP sync,
delay req
56 0x38 CS7 0xE0 Highest
PTP follow-
up, delay
response,
audio
46 0x2E EF 0xB8 High
(reserved) 8 0x08 CS1 0x20 Low
Control 0 0x00 Best effort 0x00 None
Warning: Please check thoroughly if your switch’s highest priority queue is label as #1 or e.g.
#8, because this may differ per brand. Unfortunately this is not consistent over the different
brands. Setting it wrong is worse than not having priority.

20 en | System installation design and planning DICENTIS
2018.09 | V1.8 | Hardware Installation Manual Bosch Security Systems B.V.
Switches must be configured to support DiffServ (DSCP) quality of service The switch needs
to have 4 priority queues for the DiffServ mechanism to work.
Warning: Never use VOIP QoS settings!
Requirement Standard Settings
MAC table >1000 n.a. To avoid the switch starts broadcasting unicast
packets because it runs out of space.
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
no cable loops are
used)
Rapid Spanning Tree Protocol (RSTP) is required
when (cable) loops are created for redundancy. When
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
VLANS
n.a. 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
snooping in
hardware
IGMPv3 or IGMPv2 snooping. To optimize bandwidth
usage, IGMP snooping can be used. This is useful in
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
Redundant wiring is
used
Standard Settings
RSTP IEEE802.1D-20
04
RSTP is used to allow the creation of loops for
redundancy. The switch must support changing the
following parameters to the listed values:
– Hello_Time = 9 seconds
– Forwarding_delay = 30 seconds
– Max_age = 22 seconds
Diagnostics
Link Layer discovery IEEE 802.1AB For network diagnoses using Network Docent.
SNMP SNMP For network diagnoses using Network Docent.
