ABSTRACT:
An interconnection element for an asynchronous time-division multiplex transmission system which transmits cells supplied by auxiliary lines (14a to 14d) and destined for a trunk line (10). The element comprises cell filters (11a to 11d) coupled each to an auxiliary line. The filters pass the cells to be stored in intersection buffers (12a to 12d) coupled to each cell filter when the path identification is allocated to the trunk line for controlling the reading of the cells from the intersection buffers onto the trunk line the system includes allocation circuit comprises a chain of hierarchically structured allocation elements (13a to 13d) associated each to an intersection buffer and having each its control buffer (17a to 17d). When a cell is stored in the associated intersection buffer each allocation element stores a first status in the associated control buffer and the hierarchically lower allocation element a second status in the associated control buffers. In reverse hierarchical order each allocation element evaluates the associated control buffer and releases, when a first status is available, the allocated intersection buffer for a cell to be read out.
