If one or more operators are required to control and manage the meeting, the required software modules can be installed on a PC.

A few examples are:
• Microphone management or synoptic microphone control – to configure and control delegate microphone status and determine microphone operating mode
• Delegate database – to compile a database of conference participants and specify conference-related parameters like authorizations, language of individual microphone unit display, vote weight, groups, etc.
• Electronic voting – to allow parliamentary voting, multiple choice, for and against, rating, opinion poll, etc.
• Simultaneous interpretation – monitoring and configuring the interpreter desks
• Attendance registration – to provide electronic access control and a means of delegate registration
• Message distribution – to create and send messages to individuals or audience screens
• Access control – to authorize each delegate to use certain system functions
Other possibilities to control the DCN System are via a touch screen (using software developed by AMX or Crestron) or via a synoptic panel equipped with buttons.
