PURPOSE: To provide the method and mechanism for communication between packet node support units which are mutually connected in the core of a communication equipment by point-to-point links which are physically structured and are subjected to time control in the same method. CONSTITUTION: A unit which wants transmission preliminarily sends a request to a destination unit, and a packet is transmitted between two packet mode support units of the equipment after the destination unit responds with a corresponding acknowledgment. A communication mechanism constitutes a distributed asynchronous switch; and in this switch, each packet mode support unit is provided with a packet communication circuit 9, and a point-to-point link L2 having the unit as a terminal is connected to the communication circuit 9 through a switching module 11. The communication circuit 9 gives a condition to each packet to be transmitted to another packet mode support unit of the equipment in a form of cell sequence and gives reverse conditions.
