    Symptoms Connection between DCN server and operator client will disconnect. This is occuring when using windows 10 PC's with SSD-disks. Diagnosis After restart of the DCN services it will work for a while. Also windows 10 has the 'fast startup' option enabled. This option will store settings and running services to have a fast startup. Because of this our services will start to fast and are not properly connected to the other services. And the use of SSD-disk in the server PC can cause a start up that is to fast for the services. Solution  In windows 10 there is the option enabled to store some services when the system has been shut down and start up again. This can cause problems with our services: 1: disable fast start-up option in the win 10 PC: go to the control panel of windows then go to 'power options' then click on 'choose what the power buttons do' then click on 'Change settings that are currently unavailable' then disable 'Turn on fast startup' Also the use of an SSD disk in the server PC can cause some startup problems with our DCN-NG software. You can fix this by doing the following: go to the services right-click on 'DCN-SW Server' click on 'Properties' Change startup type to 'Automatic (Delayed start)' Now restart the PC and test with these settings.

    If accidentally a wrong country code is chosen during setup, there is no other way to change it in except for re-doing the setup, which in effect erases all prior  changes made to the configuration. This article describes a way to set the country code without having to re-run the setup completely.

    DCN-NG Database Backup Note the name of the database files that need to be backed up. To check what those files are called, open the “Bosch DCN Conference Software Server Console” from the Windows notification area and note the name of the active database. Shut down all DCN-NG-related programs like ‘DCN-SW Operator Application’ and ‘DCN-SW Configuration Application’. Stop the DCN-NG service; Press the Windows button and search for ‘Services’ Open the Windows Services window Select the service called ‘DCN-SW Server (DCNNG) Right click and choose ‘Stop’. Still in the Services window, stop the services ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’ in the same way as outlined above. Open the folder that contains the DCN-NG database. On Windows 7 and 10, it’s located by default at “C:\Program Files\Microsoft SQL Server\[MS SQL Express version]\MSSQL\data”. Replace the line between [] with the right name, this can change. Right now it’s ‘MSSQL10_50.SQLEXPRESS’ Make sure that the user that is logged in is able to read/write from/to this folder. If this is not the case, the following step will not work. It’s possible to change permissions to folders for users within Windows, but that’s outside the scope of this document. Logging in to the server with an administrator account should be sufficient. Copy the right files to a safe location – make sure to copy both the file with extension ‘mdf’ as well as with the extension ‘ldf’.   DCN-NG Database Recovery Short version: simply follow the backup steps, but copy the files back to the database folder. Shut down all DCN-NG-related programs like ‘DCN-SW Operator Application’ and ‘DCN-SW Configuration Application’. Stop the DCN-NG service; Press the Windows button and search for ‘Services’ Open the Windows Services window Select the service called ‘DCN-SW Server (DCNNG)’ Right-click and choose ‘Stop’. Still in the Services window, stop the services ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’ in the same way as outlined above. Open the folder that contains the DCN-NG database. On Windows 7 and 10, it’s located by default at “C:\Program Files\Microsoft SQL Server\[MS SQL Express version]\MSSQL\data”. Replace the line between [] with the right name, this can change. Right now it’s ‘MSSQL10_50.SQLEXPRESS’ Make sure that the user that is logged in is able to read/write from/to this folder. If this is not the case, the following step will not work. It’s possible to change permissions to folders for users within Windows, but that’s outside the scope of this document. Logging in to the server with an administrator account should be sufficient. Copy the right files back to the database folder  – make sure to copy both the file with extension ‘mdf’ as well as with the extension ‘ldf’. Start all services once more; ‘DCN-SW Server (DCNNG)’, ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’. Run the ‘Repair’ function from the DCN-SW installation package. The Repair Wizard will run through the procedure of creating a new database or selecting an already existing one. Choose the existing database; If the repair process is successful, the following window will be shown: The “Bosch DCN Conference Software Server Console” from the Windows notification area will show the system is running correctly:

    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.

    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.
