ABSTRACT:
In a telecommunication network of ATM exchanges (V1, Vn) via which information transmitted in the STM mode can also be switched, error-detecting code words (EDCE) are respectively derived at an exchange input (EVi) from the content of information parts (PL) of a defined plurality of ATM cells in order to monitor the through-connections through an exchange. These error-detecting code words (EDCE) are transmitted to an exchange output in transition monitoring cells (DUZ) together with the plurality of information parts (PL) and are compared thereat to a newly formed error-detecting code word.
