Abstract

The telecommunication network is composed to a greater degree of ATM exchanges (ATM) and to a lesser degree of STM exchanges (STM). Information coming from an STM exchange (for example, STM1) ad to be switched to a further STM exchange (for example, STMy) via an ATM exchange (for example, ATM1) are packeted in short cells for through-connection through the ATM exchange (ATM1) in order to reduce the packeting time. These short cells have a shorter length when compared to the standardized message cells used for information transmission between ATM exchanges.
