Classification: CPC H | IPC H

Claim 0:
1. A network adapter for unidirectional transfer of a payload data stream to a bidirectional network interface, comprising
a first connection unit, which is physically connectable to a bidirectional network interface of a first device;
a second connection unit, which is physically connectable to a bidirectional network interface of a second device; and
a terminating unit comprising at least one bit transfer assembly and configured in such a way as to establish a bidirectional data connection to the network interface of the first device, to receive the payload data stream from the first device exclusively unidirectionally via the data connection, and not to transmit a payload data stream to the first device;
wherein the terminating unit comprises a first bit transfer assembly, which terminates the bidirectional data connection in relation to a bit transfer mode and comprises a media-dependent interface and a media-independent interface, the media-dependent interface forming a mechanical connection of the first bit transfer assembly to the first connection unit;
wherein the terminating unit further comprises a second bit transfer assembly, which is connected via a unidirectional data connection to the media-independent interface of the first bit transfer assembly;
wherein the first bit transfer assembly communicates the payload data stream unidirectionally to the second bit transfer assembly via the unidirectional data connection to a media-independent interface of the second bit transfer assembly, and the second bit transfer assembly terminates a second data connection to the second device.
