Circuit arrangement employing a microprocessor module for data conversion in a data transmission between a personal computer and communication equipment
First Claim
1. A circuit arrangement for data conversion in a data transmission between a serial data interface of a personal computer and a serial data interface of a communication equipment, comprising:
- a microprocessor module arranged between a level converting module and a decoupling module, said microprocessor module comprising a serial-to-parallel converter arranged at an input side thereof, a parallel-to-serial converter arranged at an output side thereof, and a control means for converting data according to a given desired procedure;
said level-converting module having its input side connected to the serial data interface of the personal computer and its output side connected to the serial-to-parallel converter; and
said decoupling module having means for electrical isolation of the communication equipment from the personal computer, and which has its output side connected to the serial data interface of the communication equipment and its input side connected to the parallel-to-serial converter.

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.
