Abstract

In a transmission system in which redundant message cells are forwarded via redundant transmission paths according to the Asynchronous Transfer Mode, a transmission path is blocked after the occurrence of a small number of errors in the sequence of the transmitted message cells, while for an admission of a transmission path a large number of successive message cells without error in the sequence is required.
