Abstract: The bus occupation arbitrator controls the situation when processors occupy packet bus to send or receive the data. This arbitrator enhances quality of service providing many bus occupation opportunities to the packet controller. Packet subscribers are connected to the packet switching system through a time switch (6) and the packet switching system is connected to an inter-process communication bus (5). This arbitrator provides services through X.25 protocol controlled by high-level processor (4) connected to the inter-process communication bus. A packet switching system is composed of the bus occupation arbitrator (1), a packet call controller (2) and a packet processor (3).
