Claim:
1. A method of processing a digital signal, including at least digital radio data frames, for transmission, the method comprising: compressing digital data frames, wherein the compressing comprises reducing redundancies in the digital data frames, scaling a block of samples output from the reducing by a scaling factor and quantising the scaled samples to produce scaled, compressed samples; and generating, via at least one processor, an optical data unit for transmission comprising multiple of the compressed digital data frames, said multiple of the compressed digital data frames being from multiple links and the optical data unit being configured for transport by an Optical Transport Network, OTN, wherein the compressed digital data frames are concatenated into a plurality of composite frames, and the composite frames are encapsulated to form a respective optical data unit and wherein the generation is by concatenating multiple of the compressed digital data frames into a composite frame and encapsulating the composite frame to form the optical data unit.
