Abstract
A communication system includes station ports for connecting station sets to the system. A port circuit includes a number of conference registers which are not dedicated to particular station ports but rather are assigned as needed to port circuits. When a request is made to form an N party conference call, N-2 available ones of the conference registers are then assigned to each port of the port circuit which is involved in the resulting conference call connection.
