Abstract
A circuit arrangement is disclosed for data conversion in an asynchronous, bidirectional data transmission between a serial data interface of a personal computer and a serial data interface of an expansion point of a communication equipment, particularly a subscriber terminal equipment. The procedures implemented in the microprocessor module of the circuit arrangement convert data for the selection of a telecommunication subscriber into a pulse sequence corresponding to the communication equipment, and also convert communication procedures between the personal computer and a communication equipment as well as status requests of performance features of the communication equipment.
