ABSTRACT:
A method and a packet network in which a transmitting user unit in the network transmits an information sequence either to one selected receiving user unit or commonly to a selected number of receiving user units. An information sequence is a data cell that is divided into a header and an information-carrying part. The data cell header includes a bit configuration that represents a destination address, while the information-carrying part includes a bit configuration that represents relevant information. The bit configuration in the data cell header is interpreted in accordance with the logic value of an indicated status bit, which is included in a bit field separate from the bit field that accommodates the actual address-dependent bit configuration. The logic value of the status bit is category indicative and determines whether a received destination address is interpreted as a directly coded address pertaining to a single receiving user unit or as a channel-number-coded address pertaining to a number of receiving user units.
