Apparatus for transmitting data between two parties belonging to at least one narrow band integrated services digital network
First Claim
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.

Abstract
For transmitting digital data between any parties of an N-ISDN network, the latter is interlinked with an ATM network. Two network adaptors are connected in each case with one node of each of the networks over incoming and outgoing lines of the respective network norm. The network adaptors are constructed on the side of the N-ISDN network for receiving and sending out time-multiplexed octets and, on the side of the ATM network, for receiving and sending out cells, which serve as addressed carriers for octets and have the same destination direction. The network adaptors operate free of blockages and losses.
