2DCN design
2.1 Introduction
The DCN Wireless has three parts: the wireless
network, the DCN, and the optical network. This
chapter tells how to design the DCN.
2.2 Limits
For the DCN limits, refer to chapter 1 in the “DCN
Next Generation, Installation & User Instructions”. The
DCN-WCCU has the same limitations with the
following deviations.
Make sure the following limits are not exceeded when
you design the DCN:
Limit 1: Control capacity
The DCN-WCCU wireless central control unit can
control a maximum of 95 active wired devices. The
number of passive devices is without limit. The
following wired active devices can be connected in any
combination:
• DCN-DIS Discussion Units
• DCN-CON Concentus Delegate Units
• DCN-DDI Dual Delegate Interface
• DCN-IDESK Interpreter Desks
• DCN-DDB Data Distribution Board
• DCN-FVU Voting Unit
The connected wired active devices have the same
limitations as the wireless devices with respect to the
number of audio channels (refer to section 12.4.1).
Limit 2: Single CCU only
The DCN-WCCU Wireless Central Control Unit
cannot be used in a multi CCU system.
Limit 3: Software Packages
Only use the following software packages in
combination with the DCN-WCCU Wireless Central
Control Unit:
• LBB4162/00 Standalone Automatic Camera Control
Software
• LBB4187/00 Open Interface Software
• DCN-SWSMV Synoptic Microphone & Voting
