DCN 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
Control Software
