Method for discontinuously transferring data in a point-to-multipoint access network, central unit, and network termination unit

摘要

An exemplary method and apparatus are provided for transferring data from a central unit in a network to a subscriber-sided network termination unit via a distribution network that connects the central unit with the subscriber-sided network termination unit and multiple of other subscriber-sided network termination units. Measures for providing correct data transmissions, such as scrambling or forward error correction, are applied to the data for the single subscriber-sided network termination unit before the data are combined with data for other subscriber-sided network termination units. As a consequence, there is no longer a need to completely process the transferred data at each and every subscriber-sided network termination unit.

1. A method for transferring data from a central unit in a network to a subscriber-sided network termination unit via a distribution network that connects the central unit with the subscriber-sided network termination unit and multiple of other subscriber-sided network termination units, comprising:
encoding individually multiple independent data input streams at the central unit; channel framing each of the individually encoded multiple independent data input streams after the encoding at the central unit; and performing, on each of the channel framed multiple independent data input streams individually at the central unit, scrambling and forward error correction prior to the combination of the multiple data input streams.
