Abstract
The present invention relates to a data transmission system and concerns a method for transforming user frames into fixed length cells, e.g. ATM (Asynchronous Transfer Mode), such that the fixed length cells can be transported through a cell handling switch fabric (11). A hardware implementation of this method consists of two parts, a transmitter (12.1) and a receiver (13.1), both being part of a switching subsystem (10) comprising a switch fabric (11). The transmitter (12.1) buffers user data and segments them into fixed length cells to be transported through said switch (11). The receiver part (13.1) reassembles user data on reception of these cells.
