Multi-CCU system with audio disruptions - DCN-NG

Possible causes and solution(s)

Problem description:

Audio is disrupted in a multi-CCU system, most likely after first install, re-install or reset of a multi-CCU system.

Solution:

Audio can be disrupted if CCU’s do not have a unique slave ID assigned, but instead have no number assigned (--) or a duplicate.

In order to do this, select menu 8J CCU Mode on the slave CCU, choose Multi CCU and assign an unused slave ID.

Further information:

• Use Standalone for systems with only one DCN-CCU2.
• Use Single mode if one of the DCN-CCU2’s needs to be (temporarily) isolated from the optical network.
• Use Multi mode for a multi-CCU system with more than two DCN-CCU2’s.

Notice! For DCN-CCUB2, the 8J CCU mode is not selectable.

For more details on how to set-up a multi-CCU system, please refer to the DCN-NG Operation Manual.
