TANDBERG Videoconferencing System

General use

The system has a built-in multipoint conference unit (MCU), MultiSite, which has the capability to establish
meetings with up to 4 video sites (5 if at least one site is a telephone call, ISDN/analogue/mobile).

The video calls in a conference must be connected using the same bandwidth.

A conference can consist of any combination of ISDN/IP
sites.

It is possible to have telephone meetings with up to 5
participants.

The MultiSite supports both Voice Switched and
Continuous Presence mode (see ‘MCU Services’ in
‘Advanced use’ for description of these modes).

Establishing a conference is done by first making a call
to one site. When a call is established with the first site,
the other sites are connected one by one.

It is possible to either dial out to the sites or the sites
can dial in to the MultiSite.

Both ISDN, IP and mixed ISDN/IP conferences can be

      encrypted if all systems supports encryption.

For encrypted calls, there is a maximum bandwidth of 768 Kbps for the whole conference. This means that a 3
site conference will have a maximum bandwidth of 384Kbps per connection, while a 4 site conference will have a
maximum bandwidth of 256 Kbps per connection.
