32-262 Video Conference Room


Please, let us know a day or two in advance if you'd like our help in setting up a video conference.

Quick Start: Initiating a video conference call

The videoconference unit is a Tandberg 85MXP video conference system (please see below for the technical specifications).

The unit can connect to a total of 4 video and 3 audio sites at the same time. Before you begin, the system must be in a state to make the call.
We leave our system on 24/7/365 to make it easier for users to place and receive their calls.

Note that the Tandberg’s system’s input should be set to Video 1. Use Sony Remote, TV/VIDEO Button to change the Video input.
You could also do the same by pressing the Menu button, choosing External Inputs from the selection and then choosing Video 1.


The only things you normally have to do is turn on the TV and make certain the camera is facing the correct direction (and is on).
The system is controlled and run through its remote control. If the remote is not in the room, please contact TIG immediately.

To initiate a call:
1. Press green phone handset button on Tandberg remote contro, which will bring up the call window.

Use the numeric pad on the remote to type in the number / IP adddress you are trying with whom you wish to connect (for IP addresses, press the asterisk, *, button to toggle between * and . )

To hang up a call:
1. Press the red handset button , followed by the OK button in response to the resulting window.

2. Followed by the OK button in response to the resulting window which will pop up.

Presentations


You can transmit presentations from laptops via the VGA cable on the table. Connect your machine to the video cable and press the “Presentation” button on the Tandberg to transmit it to the other side of the call or the “Self-View" button to project your display on the video screen.

Using the Video Conferencing Unit

Our Tandberg Video Conferencing system is H.320* and H.323* compliant.
  • For H.323 (IP) calls, the "phone number" to use is 128.30.30.43

  • Client software which will work with the unit:
    • NetMeeting? which can be downloaded from www.microsoft.com
    • XMeeting which can be downloaded from http://xmeeting.sourceforge.net
    • Ekiga which can be downloaded from http://ekiga.org/
    • To use these videoconference applications to connect to the Tandberg system from a computer, one can make “calls” to either 128.30.30.43 or conf-262.csail.mit.edu address.

  • H.320 is an ITU-T standard addressing video telephony specifications over ISDN and other circuit switched networks and services.

    For H.320 (ISDN) calls, the phone number(s) needed depend on the age of the connecting system and types of lines
    installed. Most video conference systems only require the primary number: 617-258-0340.

    The systems will then negotiate their bandwidth and set up additional connections as needed. Each phone number represents 2 B Channels of an ISDN line. Occasionally, the person coordinating the call mentions needing a 2x64 or 2x56 connection. This means their system dials each B channel separately. They need only dial the phone number above twice to make the connection.

    Far less often is the need for the other numbers for the system, but just in case they are:
    617-258-0341
    617-258-0354
