Abstract

The telecommunication network is composed to a greater extent of ATM exchanges and to a lesser extent of STM exchanges. For reducing the packeting time for the through-connection across the ATM exchange, information coming from an STM exchange and to be switched via an ATM exchange to a further STM exchange is packeted either into message cells that are shorter in comparison to standardized message cells used for the transmission between ATM exchanges or into message cells of the same length wherein, however, respective message parts of a plurality of STM channels that are to be through-connected to the same ATM output are multiplexed in a message cell. Given local exchanges (ATM-V) having decentralized line units (SLUR) for the connection of subscriber lines, the message cells of a plurality of STM channels are packeted multiplexed thereat without taking the exchange destination into consideration. A conversion into one of the aforementioned message cells that deviate from the standard cells then occurs in the exchange.
