System installation overviewIt 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 OMNEOcompatible Ethernet network. It is used for distributing and processing audio, video and datasignals.The DICENTIS Conference System can be quickly and easily configured as a daisy‑chainconfiguration or as a star configuration:–Daisy‑chain configuration: Uses dedicated cabling, consisting of CAT‑5e cables includingtwo additional power conductors (see Typical system setup, page 8).–Star configuration: Each DICENTIS device is connected with an individual standardCAT‑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.See also–Typical system setup, page 8 3 DICENTIS System installation overview | en 7Bosch Security Systems B.V.

System extensionThe DICENTIS Conference System is scalable from small to medium to large. This sectiondescribes what a small, medium and large system is and what the requirements are for thesesystems: 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 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 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 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 Powering Switch in the other subnets.Device Node countDICENTIS server 0DICENTIS meeting application 0DICENTIS Audio Powering Switch 1DICENTIS Powering Switch 1DICENTIS multimedia device 2DICENTIS discussion device 1DICENTIS discussion device select language 1DICENTIS discussion device voting 1DICENTIS discussion device extended 1ARNI‑E OMNEO interface 0ARNI‑S OMNEO interface 0Table 3.1: Nodes count of DICENTIS equipment3.210 en | System installation overview DICENTIS2016.07 | V1.4 | Hardware Installation Manual Bosch Security Systems B.V.
An ARNI (Audio Routed Network Interface) is used to increase the number of DICENTISdevices on a single subnet and to connect multiple DICENTIS system subnets. If more thanone 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 systemsize above 100 DICENTIS devices. It supports up to 450 DICENTIS nodes in its subnet. Italso acts as a DHCP server in its subnet.– OMN-ARNI‑E (ARNI‑E OMNEO interface): The ARNI‑E is required for increasing the systemsize above 450 DICENTIS nodes. It supports up to 450 DICENTIS nodes in its subnet. Italso acts as a DHCP server in its subnet. It can connect up to 40 subnets, each with anARNI‑S. Defining subnets and subnet masksA subnet is a logical, visible subdivision of an IP network. The number of DICENTIS devicesthat 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. SomeDICENTIS 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 liststhe number of IP address per DICENTIS device in a DICENTIS Conference System.Device IP addressesDICENTIS server (optional Meeting Application) 1Client PC running DICENTIS meeting application 1DICENTIS Audio Powering Switch 1DICENTIS Powering Switch 1DICENTIS multimedia device 2DICENTIS discussion device 1DICENTIS discussion device select language 1DICENTIS discussion device voting 1DICENTIS discussion device extended 2ARNI‑Enterprise 1ARNI‑Standard 1IP camera 1SDI video switcher 1Table 3.2: Nodes count of DICENTIS equipment Maximum number of DICENTIS devices in a string:– The max age timer should be set to 22 when RSTP is used for cable redundancy toprevent 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 timercan be reached or exceeded, because a daisy chain can be used to loop through theDICENTIS devices.DICENTIS System installation overview | en 11Bosch Security Systems B.V. Hardware Installation Manual 2016.07 | V1.4 |
– This timer (or restriction) cannot be reached when there is no cable redundancy. This isbecause 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. 12 en | System installation overview DICENTIS2016.07 | V1.4 | Hardware Installation Manual Bosch Security Systems B.V.
Multi subnet DICENTIS Conference SystemThe following figure illustrates a typical multi subnet DICENTIS Conference System with a totalof 1200 DICENTIS devices.– The system is divided over four (4) subnets, where two (2) subnets having a maximum of400 DICENTIS devices and an OMN-ARNIS are connected.– The system has one OMN-ARNIS installed in the first subnet with a maximum of 400DICENTIS devices connected (Note that only one OMN-ARNIS is allowed within a multiplesubnet DICENTIS Conference System).– Subnet four (4): When using multiple subnets, make sure that all cameras needed tocapture video of the seats are all connected to the same subnet.192.168.64.xOMN-ARNI-E192.168.64.1VLAN64192.168.65.254Ports 1, 2, 3, 4L3 SwitchVLAN66192.168.67.254Ports 5, 6, 7, 8VLAN74 (internet)192.168.1.253Ports 17, 18, 19, 20VLAN68192.168.69.254Ports 9, 10, 11, 12VLAN70192.168.71.255Internal DHPC serverPorts 13, 14, 15, 16Internet Router192.168.1.254DCNM-APSDCNM server PCDCNM-PSDICENTIS devicesMax. 420 nodesDICENTIS devicesMax. 420 nodesDICENTIS devicesMax. 420 nodesDCNM-PSOMN-ARNI-S192.168.66.1OMN-ARNI-S192.168.68.1192.168.66.x192.168.1.x192.168.68.x192.168.70.x12Figure 3.2: Typical DICENTIS Conference System with multiple subnets–1: External video switcher.–2: Dome camera.

System installation design and planningBefore you start to install system devices and connect system cabling, you should make asystem 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 isenabled. If the DICENTIS Conference System needs to be connected with the locally presentnetwork, please consult the local IT department before continuing with the installationdesign. 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 Systemand products.System capabilitiesThe 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 lengthSystem network cables (DCNM‑CBxx) lengths (2, 5, 10 or 25 m) have a direct effect on theavailable power supply capacity. The longer the system network cable, the less power supplycapacity is available to drive the connected devices. Therefore, choose the lengths of thesystem 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 = Rootswitch, 2: 2 nd level = switch, 3: 3 rd level = switch.4 4.114 en | System installation design and planning DICENTIS2016.07 | V1.4 | Hardware Installation Manual Bosch Security Systems B.V.
12 2 2 23 3 3 3Figure 4.1: Example: Switch-levels Power supply capacityThe total system network cable length and connected devices determine the required powersupply capacity. The power within the DICENTIS Conference System is supplied by:– The Audio Powering Switch and the Powering Switch, or– Off‑the‑shelf PoE Ethernet switches. Calculation toolThe calculation tool can be used to calculate the total power capacity of the system. Thismakes the design and planning of the DICENTIS Conference System easier. The calculationtool uses the power consumption of the devices and the system network cable lengths tocalculate the needed system power supply capacity.The calculation tool is on the DVD supplied with the Audio Powering Switch and is part of theDICENTIS software DCNM.iso file.

Hardware requirementsSwitchesThe following minimal requirements apply to switches:– 1 Gbit or higher with hardware switching capabilities.– Quality of Service through differentiated services with 4 or more output queues and strictpriority packet scheduling.– (Optional) IGMPv3 or IGMPv2 snooping. To optimize bandwidth usage, IGMP snoopingcan be used. This is useful in systems with >10 multicast streams, although not absolutelyrequired. Sufficient performance for handling a large number of IGMP query responses,depending on the number of (directly or indirectly) connected devices to that switch.Hardware support for IGMP is strongly recommended.– (Optional) (Rapid) Spanning Tree support, in case redundant networks are used.– (Optional) SNMPv3 support for switch supervision purposes. RoutersThe following minimal requirements apply to routers:– 1 Gbit or higher Ethernet ports.– Supports PIM‑DM or Bidirectional PIM.– Performs IP routing in hardware (i.e. a ‘layer 3 switch’) to minimize the routing delay.– Packet forwarding rate > 1,000,000 packets per second per port (e.g. 8 Mpps for an8‑port router).– Non-blocking backplane per switching port, i.e. 2 Gbit per port (e.g. 16 Gbps for an8‑port router).– MAC address table of at least 1000 addresses per directly connected subnet. 4.216 en | System installation design and planning DICENTIS2016.07 | V1.4 | Hardware Installation Manual Bosch Security Systems B.V.

Redundancy optionsDICENTIS Conference Systems can be created with network redundancy. This ensures that thesystem 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 yourDICENTIS Conference System. Each option can be combined in the DICENTIS ConferenceSystem, providing you observe the redundant cabling limitations. Refer to:–Redundant cabling for DCNM‑APS/DCNM‑PS units, page 22.–Redundant cabling for DCNM-APS2/DCNM-PS2 units, page 23.–Redundant server PC, page 25. Notice!Rapid Spanning Tree Protocol (RSTP) must be enabled in the DICENTIS Conference Systemfor these redundancy options to work correctly. 4.4 DICENTIS System installation design and planning | en 21Bosch Security Systems B.V.

Redundant cabling for DCNM‑APS/DCNM‑PS unitsThis section describes how to create redundant cabling for DCNM-APS or DCNM-PS units. Themaximum number of Ethernet devices in the loop (including the root switch) is 22. In a systemwith 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 consumemore 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 thelargest loop. The # sign shows the way the devices are counted.In the example below up to 21 discussion devices can be connected. 1233#1#2 #22Figure 4.6: DICENTIS devices connected with redundant cabling to the same DCNM-APS / DCNM-PS typeunit1: DCNM-APS or DCNM-PS.2: DICENTIS devices.3: DICENTIS cabling (redundant loop).Cabling possibilities (DCNM‑APS/DCNM‑PS) Limitations/requirementsConnect the DICENTIS devices in a daisychain configuration from a high power socketon a DCNM-PS or DCNM-APS to another highpower socket on the same DCNM-PS orDCNM-APS.The redundancy is for cable only. If theDCNM-PS or DCNM-APS fails, all DICENTISdevices connected to that unit will also fail. If a single DICENTIS device fails, the otherDICENTIS devices in the daisy chain willcontinue to work. To enable redundancy, Rapid Spanning TreeProtocol (RSTP) must be enabled.You can use any of the high power sockets (3,4, or 5) to create the daisy chain.The redundant loop must be connected tothe same DCNM-APS or same DCNM-PS.See also–Power supply capacity calculation plan, page 17 4.4.122 en | System installation design and planning DICENTIS2016.07 | V1.4 | Hardware Installation Manual Bosch Security Systems B.V.
Redundant cabling for DCNM-APS2/DCNM-PS2 unitsThis section describes how to create redundant cabling for DCNM-APS2 / DCNM-PS2 typeunits. The maximum number of Ethernet devices in the largest possible loop (including theroot 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 consumemore 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.

Cabling possibilities (DCNM-APS2/DCNM-PS2)Limitations/requirementsCreate a redundant loop by connecting theDICENTIS devices in a daisy chainconfiguration from a high power socket on aDCNM-PS2 / DCNM-APS2 to a high powersocket on another DCNM-PS2. The redundant loop between two DCNM-PS2units is for power and signal. If one of theDCNM-PS2 units fails, the other DCNM-PS2unit will supply power and signal to theDICENTIS devices in the daisy chain.The redundancy is for cable only. If theDCNM-PS or DCNM-APS fails, all DICENTISdevices connected to that unit will also fail. To enable redundancy:– Rapid Spanning Tree Protocol (RSTP)must be enabled in the DICENTISConference System.– a network switch with redundant powersupply, should be connected to theDCNM-PS2 / DCNM-APS2 units, asshown in the previous figure.You can use any of the high power sockets (3,4, or 5) on either of the DCNM-PS2 units tocreate the daisy chain/redundant loop.For example, high power socket 3 on one unitcan be connected to high power socket 4 onanother unit.Note: The redundant loop must be connectedto another DCNM-PS2 type unit. You cannotuse DCNM-PS / DCNM-APS type units tocreate redundant loops for power.You can create a redundant loop for signalonly, by connecting the DICENTIS devices in adaisy chain configuration to the same DCNM-PS2 or DCNM-APS2, although this is notrecommended.The DCNM-PS2 unit is designed to reducecost of ownership, for example, by allowing amaximum of three redundant loops to beconnected between two DCNM-PS2 units.The redundant loop will function in the sameway as a DCNM-PS / DCNM-APS type unit.Refer to Redundant cabling for DCNM‑APS/DCNM‑PS units, page 22.

The maximumnumber of Ethernet devices in the largest possible loop (including the root switch) is 22.The total number of devices allowed in a loop depends on:– The type of device connected in the loop (for example, DCNM-MMD2 devices consumemore 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 thelargest loop. The # sign shows the way the devices are counted.In the example below up to 17 devices can be connected. #4 #20#2#3 #21#22#11144555322Figure 4.8: Redundant DICENTIS server PC with redundant components and cables1: DICENTIS system/client PC2: Network switch (with optional redundant power supply)3: DCNM-APS24: DCNM-PS25: DICENTIS cabling (redundant loop) For this option to work the DICENTIS Conference System has to be run in combination withEverRun Enterprise software from Stratus Technologies.
