Abstract
The invention relates to an asynchronous time-division multiplex transmission system comprising an interconnection element, which element transmits cells supplied by auxiliary lines (6) and destined for a trunk line (8) at a preset interconnection element transmission rate and which comprises cell filters (7) coupled to each of the auxiliary lines, which filters pass the cells for storage in intersection buffers (15) coupled to each cell filter when the path identification contained in the cells is allocated to the trunk line. An output buffer (17) supplying cells to the trunk line is connected to the outputs of the intersection buffers. The cells are transmitted between the intersection buffers and the output buffer at a temporary transmission rate which is increased relative to the element transmission rate.
