摘要： The system uses a 3B2T line code, i.e. one in which sets of three or triplets of binary digits are converted into pairs or duplets of ternary elements. All nine of the possible ternary duplets are used, in such a way that the same ternary duplet does not occur twice consecutively. This is done in one version by using the ninth duplet 00 as a repeat indicator, and in the other version by a conversion process in which each conversion operation takes into account the result of the preceding operation.

摘要： A method for marshalling an additional outstation (3) of a time division multiple access (TDMA) telecommunications system including a basestation (4) and a plurality of outstations (1, 2), such as a passive optical network (PON). A sequence is transmitted from the additional outstation (3) to the basestation (4) at a level below the noise sensitivity of a receiver (49) of the basestation (4), detected at the basestation and its phase discrimated. From the discriminated phase the loop delay to the additional outstation is determined and the outstation instructed to realign its transmission accordingly. The sequence and its phases are detected by a correlation process.

摘要： A first (receiver), for example, pseudo random binary sequence (PRBS) generator (6) is synchronised with a second identical PRBS generator (2) at a tramsitter by adding a PRBS (u(x)) to a data stream (w(x)). The data stream includes a known value at periodic intervals. The received data is framed (5) and thus the position of the known data values determined. The received data is sampled at these positions to produce a sequence of samples (s(x)) comprising a sampled version of the transmitter PRBS. The phase of the transmitter generator (2) is determined for the samples and the phase of the receiver generator (6) adjusted to correspond. (Fig. 1). Implementation with sequence generators other than binary sequence generators are also discussed.
