Abstract

A conferencing bridge provides conferencing capabilities for a plurality of input lines and for a plurality of output lines. The conferencing bridge has a signal processor which processes the audio information transferred between the input lines and the output lines. A plurality of codecs analog to digital conversion and digital to analog conversion for interfacing the signal processor to the plurality of input lines and output lines. A control processor is operatively connected to the signal processor and controls and operation of the signal processor as well as the conferencing bridge through number codes that are inputted to the conference bridge via the telephone key pad. A tone converter converts the inputted tones to digital information to which the control processor will respond. The signal processor provides not only identification of the telephone line on which a speaker is talking but also performs an amplitude adjustment so that there is a minimum loss involved for the conferencing network.
