ABSTRACT:
A device realizing a method for handling incoming data packets first forwards these data packets from a first unit towards a second unit, extracts within the second unit the header and user information, and performs a step of selecting and processing the header and user information thereby providing selected information in accordance with predetermined information. A selection of at least predetermined part of the selected information is followed by a step of looping back this at least predetermined part of the selected information from the second unit to the first unit. A device realizing a method for assembling and transmitting data packets first generates header and user information within a first unit, transmits this information towards a second unit, which further processes and assembles it to generate therefrom data packets. These are then transmitted back from the second unit via the first unit to an output terminal.
