ABSTRACT:
An audiographics conferencing arrangement for use in a business communication system allows the conferees to exchange displayed text and/or graphics stored locally in their respective data terminals. The conferees may change the displayed text and/or graphics and such changes are automatically distributed to the other data terminals so that all of the conferees view the same information. Moreover, a data terminal and its associated telephone station set may be included in an audiographics conference connection even though they are not directly served by the business communication system. In addition, one of the conferees may establish concurrent with the original audiographics conference connection a second audiographics conference connection with one or more other data terminals and transfer information obtained from one conference connection to the other conference connection.
