Inventor: MARIGGIS ATHANASE
IPC: H04J3/16
Filed: 2000-01-21
Abstract: When SDH signals are transmitted, higher order signals such as STM-N (N~1) signals are transmitted. In order to avoid switching problems with the STM-1  switching networks that have been used until now, the STM-N signals are spli t into in N STM-1 signals according to the known virtual concatenation mode. However, these take different paths in the network which leads to different propagation times. The invention solves this problem by contacting FIFO memo ry devices at the receiving end with relative addressing so that the useful dat a stored there can be read out.
