1. An apparatus for transmitting digital data between any first party and a second party assigned to the first party, the parties belonging to a single, common or to two mutually independent N-ISDN networks, comprising:

  • said N-ISDN network or networks altogether having at least two ISDN nodes;

    an ATM network having at least two ATM nodes;

    at least two network adaptors, to which at least one ISDN node and at least one ATM node are connected over incoming and outgoing lines of a respectively assigned network norm;

    wherein each network adaptor includesa first code converter connected to a line coming in from the ISDN network for converting each time-multiplexed, incoming octet into an unambiguously allocated, destination-coded octet;

    a sorter, which is connected in series with the first code converter, for putting out each destination-coded octet on one of several outputs, which outputs correspond in each case to a destination allocated to the destination code of the respective octet;

    filling stations, which are individually connected in series to the outputs of the sorter for filling sorted, destination-coded octets into the payload of the respective cells, which are to be provided and are intended for the particular destination, which corresponds to the respective output of the sorter;

    an emptying station, which is connected to a line coming in from the ATM network for emptying the respective octet from the payload of the incoming cells and for reading this octet into the sorter;

    a second code converter, which is connected in series with the sorter for converting incoming, destination-coded octets into unambiguously allocated octets of the N-ISDN network, which are to be transmitted in time multiplex fashion; and

    at least one logic with assigned memories for controlling the first and the second code converter and the sorter,said network adaptors being constructed free of blockages for receiving time-multiplexed octets from the lines coming in from the respective N-ISDN network or sending out time multiplexed octets on the lines going out to the respective N-ISDN network;

    said adaptors for filling the octets received into several cells in the payload;

    said adaptors for sending out and receiving cells on the lines going out to the ATM network and from the lines coming in from the ATM network respectively;

    said cells, as carriers of octets of an N-ISDN network, being specially marked; and

    said adaptors also for emptying the octets from the payloads of incoming cells.
