Abstract: For a dual leaky bucket ATM bit rate monitoring wherein the peak bit rate is monitored in a first leaky bucket unit and the maximum cell plurality of a full rate burst is declared, the duration of peak rate bursts is monitored in a second leaky bucket unit with a first counter respectively reset to 0 when the counter reading returns below a defined value.

Abstract: For dual leaky bucket ATM bit rate monitoring, a peak bit rate is monitored in a first leaky bucket unit and a maximum cell plurality of a full rate burst is defined. A duration of peak rate bursts is monitored in a second leaky bucket unit with a first counter respectively reset to 0 when the counter reading returns below a defined value. An average bit rate is monitored with a further counter having a lower response value that is incremented with a cell rate which is smoothed dependent on a degree of filling in an additional cell counter.

Abstract: A broad-band communications network having at least one packet switching network, wherein the transmission of communications signals occurs in packets of a fixed length. Packing/depacking units are provided at the network interfaces to form and break up the packets. After trunking, the degree of packet filling of the packets provided for communications signal transmission is adjusted on the basis of the trunking information transmitted and on an individual connection basis in a packet switching system associated with the packet switching network. Information regarding the control signal containing the adjusted degree of packet filling is transmitted to all packing/depacking units involved in the connection to be established to set the packing/depacking units accordingly.

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.

Abstract: With the switching node at least one coupling element is associated which has a number n of input lines and n output lines optionally connectible to the input lines via a space switch with a buffer store being assigned to the input lines in which k data packets occurring sequentially on the particular input line are storable before being routed further to the output lines indicated by the address signals contained in the particular data packet. The buffer stores have each a plurality m.ltoreq.k output terminals via which simultaneously m data packets stored in the particular buffer store and to be routed further to m different output lines are suppliable to a space switch having m.times.n input terminals and n output terminals.

Abstract: The present invention is directed to a method for user prompting at a digital telephone station, comprising a twelve-key keyboard for subscriber selection and further keys, here eight, for subscriber services, and comprising a display for written or oral messages deposited in a mailbox assigned to the telephone station an a one-line or multi-line display, and whereby at least a portion of the keys can be represented on a touch sensitive liquid crystal surface in the form of pictograms.
