ABSTRACT:
Arrangement for generating pulse code modulation values in a telephone set, comprising a microprocessor which includes a working store, in which the microprocessor and the working store are connected by a data bus and an address bus, further including an output circuit for outputting the pulse code modulation values, an output memory connected thereto for storing the pulse code modulation values to be output, the working store and the output memory being incorporated in a single memory circuit. The arrangement is preferably structured in such a way that it comprises an addressing device for generating, in response to the microprocessor's addressing of a random location of the output memory, an address of an output memory location to be read out.
