Abstract
A broad-band communications network consists of at least one broad-band packet exchange for transmission of communications signals in packets of a fixed length and one telephone exchange connected to the broad-band packet exchange by means of at least one interworking unit. Packing/depacking units are provided at the interfaces of the packet exchange to the subscriber's sets and within the respective interworking units. A control signal is sent following trunking to the packing/depacking units involved in the connection to be established for connections with a network transfer. The control signal controls the packing/depacking units such that packets of a fixed length intended for transmission of speech signals are formed or broken up, in accordance with a adjusted degree of packet filling which is reduced in comparison with the full packet capacity.
