ABSTRACT:
Resequencing system for a switching node (SN) of a cell switching system wherein cells or packets, of fixed or variable length, transmitted from an input to an output of a switching network (SNW), are subjected in the network to variable initial time delays for instance because they follow different paths therein. To restore at the output the sequence with which the cells were supplied to the input the cells at the output are subjected to additional variable complementary time delays which are so chosen that for each cell the sum of the two time delays is substantially equal to a predetermined total value.
