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 8).

– 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 8) 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

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.

– 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.

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.

Figure4.1: Example: Switch-levels

2017.12 | V1.6 | Hardware Installation Manual Bosch Security Systems B.V.

DICENTIS System installation design and planning | en 15

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
