Abstract:
A character block or logic circuitry is disposed between the line unit receiving telegraph characters on several lines and a central processing unit of a telegraph switching center. The character block reads out the characters stored in the line unit and, during transfer to buffer stores, analyzes the characters and send corresponding signals to the central processing unit. This arrangement reduces the work load on the central processing unit.
Abstract:
An auxiliary translator is added to the main translator of a system for analysing telegraph characters. The auxiliary translator has a number of inputs equal to the number of different telegraph characters of the alphabet employed and a plurality of outputs each providing a binary value made up of a number of binary elements lower than the number of binary elements making up the telegraph character. This arangement reduces the size of the main translator employed in prior art systems to analyse telegraph characters.
