The invention relates to a programmable ciphering analysing receiver for the Pentaconta Crossbar-type automatic telephone exchanges, destined to transferring the information received and processed by different equipments of an own or distant telephone exchange (CTA 1 and CTA 2 ), including a disk beat buzzer (TD), a call collecting unit (LTBS) and a local register (RL) within the assembly of its equipments, the programmable ciphering analysing receiver (RACP) being made up of an interface circuit (IA), for interfacing with the subscriber's private line (a and b), for permitting the selection information detection both in direct current and in alternating current, consisting in a number of maximum 20 figures, said information being processed by a processing unit (UC), made by using a microcontroller, having a database stored inside the main memory thereof, said database being modifiable from exterior by means of a user interface (IU), the processing being made depending on preset criteria, as well as on the calling subscriber's own number, the information being then stored and analysed, the result of the analysis being transmitted both towards the equipments of the own telephone exchange (CTA 1) and towards those of the distant telephone exchange (CTA 2 ), the processing unit (UC) being also connected to a standard interface (RS), which permits the data transfer between the processing unit (UC) and the calls connecting unit (LTBS) within the own telephone exchange (CTA 1).
