Abstract: An ATM communication system with a modular structure for the switching of packeted cells (Z) between ATM communication terminals (KE) over dial-up or fixed connections has a switching device (SB) and a remote control device (CB). Arranged in the switching device (SB) is an ATM switching matrix module (ASN), at least one subscriber line module (SLMP), a communication module (KM) and a clock module (TM), and the control device (CB) is formed by a personal computer (PC) which controls the switching device (SB) in terms of operation, switching and administration and in which a processor-controlled communication adaptor (CA) is provided for the exchange of information with the switching device (SB).

Abstract: An ATM communication system (KS) for the connection of ATM communication terminals (KE) is formed by a switching device (SB) and a control device (CB). In the switching device (SB), a transport program module (TSP), and also a dependability subprogram structure (DEP-SB), an operation subprogram structure (CP-SB) and a switching subprogram structure (AM-SB) and a message distribution program module (MD) are provided in a multi-tasking operating system (OSS). The control device (CB) has a multi-tasking operating system (OSC) with a transport program module (TSP), a process management program module (PVP), and also a switching program structure (CP), a dependability program structure (DEP), an operation program structure (AM) and a communication program structure (KMP).

Abstract: Circuit-associated programming signals and at least one additional, circuit-associated programming routine are generated and are then arranged in a testing device. The function check of printed circuit boards equipped with programmable integrated circuits is provided by measuring sensors which may be, for example, needle adapters. A programming of programmable integrated circuits on equipped PC boards results within the framework of the function test. A considerable cost reduction in the manufacture of PC boards for assemblies with programmable integrated circuits may be achieved. Separate programming at a special programming location may be avoided as well as avoiding a program-associated storing of the programmed integrated circuits.
