摘要： A communication system working according to an asynchronous transfer mode comprises ATM communication equipment units connected to one another, whereby a plurality of concentrator equipment units are connected to at least one of the ATM communication equipment units. The concentrator equipment units together with the corresponding ATM communication equipment units are thereby arranged in a ring line system. Within this ring line system, each of the concentrator equipment units is connected via a separate virtual path to, on the one hand, the corresponding ATM communication equipment unit and, on the other hand, to each of the remaining concentrator equipment units. A plurality of virtual connections having defined transmission capacities can be respectively conducted via the individual virtual paths. Particulars with respect to the transmission capacities already occupied for established virtual connections are kept separately for the individual virtual paths in the corresponding ATM communication equipment units and are updated with every set-up and clear-down of a virtual connection. According to the measure of these particulars, a new virtual connection is thereby allowed only given a transmission capacity on the respective, virtual path that is still adequate.

摘要： Coupling circuitry for multistage coupling fields in telecommunications networks, especially time-multiplex telephone switching systems, with switching matrices and intermediate lines that connect them from coupling stage to coupling stage.The multistage coupling field has intermediate-line wiring wherein a number of intermediate lines extends in parallel in a group of intermediate lines from every switching matrix in the first coupling stage to every switching matrix in the second coupling stage, the number being large enough to prevent interior blockage even while multichannel connections are being established. The number of switching matrices in the second coupling stage is for this purpose one more than double the quotient, rounded off to a whole number, of the difference between the connecting lines connected to the input end of one switching matrix in the first coupling stage and the maximum number of connecting lines or intermediate lines to be seized per multichannel connection and the difference between the number of intermediate line per group of intermediate lines increased by one and the maximum number of connecting lines or intermediate lines to be seized per multichannel connection.
摘要翻译：用于电信网络中的多级耦合场的耦合电路，特别是时分复用电话交换系统，具有将它们从耦合级连接到耦合级的开关矩阵和中间线。多级耦合场具有中间线路，其中多条中间线在从第一耦合级中的每个开关矩阵到第二耦合级中的每个开关矩阵的一组中间线中并联延伸，该数量足够大以防止即使在建立多通道连接的同时内部堵塞。第二耦合级中的开关矩阵的数目是为了这个目的，将连接到第一耦合级中的一个开关矩阵的输入端的连接线之间的差异的整数乘以商数的一倍以上，每个多通道连接要连接的连接线或中间线的最大数量以及每组中间线的中间线数之间的差增加一个，并且每个多通道连接将要占用的连接线或中间线的最大数量。

摘要： For a virtual connection set up using an asynchronous transmission method which transmits information cells with a rate which is not constant over a relatively long period, the maximum rate may be limited, on the one hand, and the access of the information cells to a trunk line carrying information cells of a plurality of virtual connections may be regulated, on the other hand. As a result, the rate of information cells of a virtual connection is limited.

摘要： To the switching node belongs at least one coupling element which has n input lines and n output lines optionally connectable to them via a space switch. To each of the input lines a buffer store is assigned in which k data packets are storable and which has m.ltoreq.k output terminals via which m data packets are simultaneously suppliable to the space switch having m.times.n input terminals and n output terminals. The storage addresses, under which the data packets to be routed are stored in the individual stores, are stored in accordance with the address signals contained in the data packets and stored in queue buffer stores assigned to the output lines. The queue buffer stores are cyclically accessible by a central control device for making available storage addresses. On the basis of storage addresses made available in such manner the central control device, on the one hand, controls the setting of the space switch and, on the other hand, the output of data packets from the buffer stores.
