Abstract
In a time division multi-access communications system each burst in each slot commences with a preamble and the clocks used to control the sequence of operations are synchronized by means of these preambles. In particular the outstations control their transmissions to the node by timing pre-set delays from the receipt of the preamble. In a preferred embodiment the pre-set delays are adjusted by signals from the node so that bursts arrive at the node in correct sequence.
