Abstract: An ATM switching equipment is provided comprising a switching network (ASN) and at least one server switching unit (SSC). The server switching unit (SSC) contains an AAL2 switcher (ASW) that is configured for simultaneous processing of a maximum plurality (m) of incoming connections. An AAL2 routing list (RL1 . . . RLm) is provided for each of these connections, and a microprocessor (MPR) is configured to limit the allowable value range for VPI/VCI values in the header of the ATM cells according to the plurality of AAL2 routing lists, so that only the corresponding VPI/VCI coding bits are taken into consideration at an interface to the switching network.

Abstract: The invention relates to a method for determining an allocation time (NS) in a scheduler (9) with a fixed number (K) of allocation times, whereby a defined allocation time of the number of allocation times is determined for a time to be allocated using a hash function, and whereby the actual progression of time is represented on this fixed number (K) of allocation times also using the hash function. A method for determining a sending time (TST) for a data cell (13) over an output line (3) of a packet oriented transmission system, particularly in accordance with the ATM standard, is advantageous when a determined sending time (TST) is entered into a scheduler (9) as the time to be allocated for the data cell (13). This advantageously ensues by using the above-mentioned method. Additional areas of application are schedulers in machine installations, switching systems in, in particular, packet-oriented communications systems or multiplexers for multiplexing data.

Abstract: A method for optimizing the transmission of ATM cells via connection sections wherein, in order to decide which ATM cells stored in waiting ques are to be multiplexed onto further connection sections and at which point in time, connection information together with a respectively allocated time mark is stored in a sorted list according to the criterion of a predetermined ordering rule. Such rule is fashioned such that the time value assigned to the connection information is stored in a predetermined sequence in the sorted list and a check is carried out when new connection information is stored to see whether the time value allocated thereto can be entered into the sorted list.

Abstract: An ATM communication system for statistical multiplexing of message cells has a plurality of upstream interfaces, at least one multistage funnel of switching elements connected thereto, and at least one downstream interface. Each of the switching elements comprises a plurality of inputs and at least one output to which a logical queue is associated. The logical queue of each of the switching elements is common for different traffic classes. For the filling of the logical queues to each of the traffic classes, a predetermined threshold is defined. In case of exceeding the threshold for the respective traffic class by receiving a message cell for this traffic class, a back pressure signal is transmitted only to the switching element or upstream interface, respectively, just transmitting this message cell. The transmission of message cells is stopped by this switching element or upstream interface, respectively, for a predetermined period of time periodically until a resetting of the back pressure signal.

Abstract: The input and/or output device for process data has a mounting rack (1), as well as a plurality of modules (2) fastened on the mounting rack (1). A process connector (4) can be inserted into each of the modules (2) on the front side in each case. Each module (2) has a circuit board (17) which is arranged in a housing (8), as well as a terminal strip (18) which is connected non-positively to the process connector (4). The terminal strip (18) serves to receive contact pins (26) which interact with contacts of the process connector (4). The input and/or output device is intended to demonstrate a high degree of operational reliability even in the case of a high level of mechanical and electromagnetic stresses.

Abstract: The input and/or output device for process data exhibits a subrack (1) and at least one assembly (2) mounted on the subrack (1) and a process connector (4) which can be frictionally introduced into the at least one assembly at the front. The at least one assembly (2) exhibits a circuit board (17) arranged in a housing and a connector strip (18) which is frictionally connected to the process connector (4). This device is to be of simple and appropriate design and, at the same time, loading of the circuit board (17) with large mechanical forces is to be avoided. This is achieved by the fact that the connector strip (18) is mechanically rigidly connected to the housing and contains elastically deformable terminal pins (21) on which the circuit board (17) is supported.

Abstract: The connector keying system has a first connector housing (4) with a mating surface and a second connector housing (2) with a mating surface. The second housing (2) is movable relative to the first housing (4). In this system a programming of the keying shall occur automatically as the connector housings (2, 4) are mated together. This achieved as follows: A keying means receiving recess (23) is provided on the mating surface of the first connector housing (4) proximate an end thereof. A keying means is provided in the recess (23). The keying means has a first (22) and a second keying member (24). The first keying member (22) is secured to the first connector housing (4) by first securing means (50, 52). The second keying member (24) is frictionally maintained in corporation with the first keying member (22). The second keying member (24) has second securing means which are provided to cooperate with the second connector housing when the connector housings (2, 4) are mated together.
