ABSTRACT:
In a data transmission system of the TDM type both circuit-switched and packet-switched connections can be set up. Circuit-switched connections, being real time, e.g. voice, are given priority, but all time slots are available for packets when not in use for circuit-switched connections. Thus the ratio of the two types of connections is automatically adjusted according to traffic conditions.
