Abstract (en)
[origin: WO02082713A1] Local source data is first sampled (20) at an original sampling rate and the resampled (30) at first sampling rate which is equal to the framing rate for transmitting said data to the remote source. The resampled local source data is then delayed (40) by the transmission time (36) between the local and remote data sources. The data from the remote relay which is resampled (48) at the remote source at the first resampling rate (48) and the delayed resampled data (42) at the local source are both then resampled (46) at a second resampling rate, at an original sampling rate, to produce aligned data at the local source.
