Abstract: The invention includes a signal receiving and a signal transmitting unit (61) adapted for converting an information-carrying signal (70c) received at a first transmission rate to an information-carrying signal (70d') transmitted at a second transmission rate which differs from the first transmission rate. One signal receiving input (70c, 70d, 70e) of several available inputs, where each input is adapted to a transmission rate which differs from the transmission rates of remaining inputs, can be connected (93) to one signal transmitting output of several available outputs (70d', 70e'), where each output (70d', 70e') is adapted to a transmission rate which differs from the transmission rates of remaining outputs, in dependence on signals occurring on one or more control conductors (71), wherein a selected control conductor and/or selected signal information selects and initiates a conversion mode having a selected conversion index.

Abstract: The invention relates to a tele- and data communication system, including circuits (8, 14) containing transfer paths (10, 12, 16, 18) for data flows, and having functionality for error isolation of parts of the system. At least partially, where possible, parts of the circuits of the system are error isolated by logical partition into function blocks of two types. More particularly there is a first type, in which a complete corresponding function block (18, 20) need not necessarily become eliminated by an occurring error, and a second type (22, 24) in which the contrary is true. The transfer paths (10, 16) of a function block of the first type are isolated from each other for enabling shutting down such an erroneous transfer path from traffic by software control.

Abstract: In a packet switch, which is intended for packets of constant length, and which, between switch ports, is divided into a number of nodes (12) and transmission links (14), where the nodes carry out space selection and the transmission links offer point-to-point transmission between the nodes, link grouping is carried out. More particularly, from multiple parallel physical links coming into the switch, link groups are produced, each in the form of a logical link with a bandwidth that is the sum of the bandwidths of the physical links included in the link group, said logical link being restored to outgoing parallel physical links from the switch. One or more link protocols (G1, G2) are used according to which a label in the packet's header is made to describe a route that holds together the grouped links through the entire switch, such that bits in the label describing the route over a certain transmission link are the same for packets belonging to the same link group.

Abstract: The present invention relates to a multiplexing/demultiplexing unit constructed as an integrated circuit and as a block on a sub-surface of a silicon surface, such as a digital Bi-CMOS circuit and utilizing a CMOS section laid on said circuit, wherein a first sub-surface of a silicon surface carries a first array (41') of signal input and output circuits, and a second sub-surface carries a second array (41') of input and output circuits. A region (50) is located on the silicon surface between the first and the second sub-surfaces or located in some corresponding manner and is intended to carry control logic (51), memory stores (52), buffer circuits (53), synchronizing circuit arrangement (54) and the requisite conductors and functions to process signals, store signals and transmit the processed signals on selected output circuits both when multiplexing and demultiplexing signals.
