Abstract
A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.
