Abstract

A communications network having a multiport data conference system is disclosed. The data conference system includes a multilevel processor arrangement with the lower level port processors communicating directly with data terminals and higher level processors controlling conference configuration. Data to be conferenced is put in a buffer memory which is shared by all levels of processors. The ports can be configured to be compatible with different type terminals that operate at different data speeds.
