ABSTRACT:
A service switching point having a direct memory access controller is used for controlling a data transfer between a data memory and an input/output device. There is proposed to provide the direct memory access controller for generating a first part of an address, and a generator for cyclically generating a second part of the address. Such a service switching point can preferably be used in PCM 30 transmission networks when a subscriber device is coupled to the service switching point via a DSV2 connecting line while 2.048 Mbit/s data rates occur.
