Connecting

What is a Bridge?

  • A Bridge is a special computer that is required for a videoconference (VC) when more than two VC machines have to be linked, or to join incompatible VC machines.
  • The videoconferencing Bridge is located in the Edward Ford Building A27, at the University of Sydney (Room 220).
  • At AVIT, we have our own centralised Bridge, controlled by the AVIT Videoconferencing Coordinator at Sydney Medical School.

What can the AVIT Bridge do?

  • Join multiple sites
  • Join sites using different speeds
  • Join incompatible machines
  • Control the way the conference is viewed by all of the sites
    Can dial, or be dialled, by participating sites
  • Our Bridge is an Ezenia! 2020 MCS Workstation running Version 6.3

The AVIT Bridge is able to connect a maximum of 12 sites (any combination of the following):

  • Max 8 ATM sites
  • Max 5 ISDN sites
  • Max 4 IP sites
  • Max 12 telephone
  • 8MB (bandwidth)
  • 1 continuous presence call/conference
  • 1 Collaborates Conference (can collaborate a number of rates in one call - multiple speeds of connection can be linked at once)

Direct Dialling

  • If there are only two sites in your conference, you might be able to direct dial each other
  • To do this, both VC machines will have to be either: both ISDN; or both IP (IP and ISDN are transmission types)
  • If you want your conference to be direct dial, you will have to do a test call between the two sites beforehand.
  • Even if your conference will be direct dial, a booking form must still be submitted for the conference.
