    The APS in question was running on v1.12 and needed to be upgraded to v2.60 and any firmware updates would continually fail (even other intermediate versions). The below procedure is not specific to this update and can also be used for updating from other older versions.

    Question Can a CCU be used in the same DCN-NG system as a CCU2 or CCUB2? Answer No, this is not possible. Mixing CCUs and CCU2/CCUB2s in a DCN-NG system is not supported. It’s also not possible to use a CCU as a spare unit in case of failure of a CCU2/CCUB2 in a DCN-NG system.

    Description: The RESTful API of the CCS1000D is used in order to get a clear view of the state of the discussion devices’ microphones (amongst other things). However, when a Priority call is made, the other speakers still show as active even though they are muted in reality. Solution: This is actually as it' supposed to work. The reason the speakers still show as active is because they remain in the speaker list while the priority call comes through (in this case, the chairperson making an announcement overruling all other parties) is that in the system there’s a difference between speakers being muted and speakers being removed from the speaker list. In this case, after the priority call ends, the speakers are unmuted and can resume the discussion. It’s also possible to configure the system to stop all speakers and remove all waiting participants from the request list. If the system is setup in this way and the chairperson starts speaking, the system will indeed erase all other speakers and waiting speakers. The API can be used to create a custom interface. This means that logic can be added so the preferred outcome is created. In this case it means that the custom interface needs to poll for the speakers list but also needs to take in account that when a priority call comes through (also pollable) this means the others are muted. Using these two givens can then be used to for example change the icons of the speakers to a ‘muted’ state in the custom interface.

    DCN-NG is set-up in a multi-PC environment, all required licenses are installed. When trying to connect to the server from the secondary PC, the Operator Application takes a long time to start and once it does, the screen is simply blank and the server icon mouse-over shows the application is disconnected. When pinging the server from the secondary PC, the ping goes through without issues.

    Product(s) affected: DCN-NG systems with master & slave CCU set-up Version(s): all Problem description: A DCN-NG system will be installed in a building which uses different VLANs for different floors in the building. They want to be able to have interpreters on one floor (in one VLAN) and the rest of the system on another floor (in another VLAN). To this end they have connected their Master CCU to another VLAN than their Slave CCU. This set-up does not work. Question is; should this work and if not, why not? Solution: This cannot work in a DCN-NG system because of the way the system is designed. The communication between the CCU’s, at start-up of the system, uses broadcast messages which are not routed by network devices. These messages have a time-to-live (TTL) of 1, which means that once they attempt to cross into another (V)LAN, the messages are not propagated by the routing (L3) switch. The reason is that the TTL of the packet is decreased every time it traverses from one network to another. When the TTL’s value reaches 0, the packet is dropped by the routing device. Therefore, the broadcast packet will never reach the other CCU, resulting in error messages like “No Master CCU” on the Slave CCU. Therefore the system should be installed on the same (V)LAN. This usually does not pose any technical problems as (V)LANs can be distributed over multiple network devices without issue, it’s just that the predictability of where a device is physically located is less in this instance.

    If something is not working well in the Microsoft Windows Server it will be recorded in the Event Viewer (log files) and can indicate where the error occurs. This is a good tool for the Technical Support to figure out if there are considerable issues in the Windows and other programs.

    The DetectDevices script was developed to give a fast feedback on connection problems or any other failure within the DICENTIS wired system. It will simulate a device and give out an advanced log file which can be used to track sporadic or normal connection problems. The technical support will provide this tool to get a deeper look into some issues if needed.
