Abstract: In a switching center controlled by two computers operating, for example, in the load-sharing mode, each of said computers has an access to each peripherical unit through an interface circuit. This interface has two functions: Retiming between the computer clock and the PCM clock, Preselection of the address concerned, in a peripheral unit, by an instruction sent by the computer and transmission of the data contained in said instruction.

Abstract: signalling Instructions connected to a PCM switching network in the same way as a number of trunks. The information it receives is in the form of program instructions supplied from a central processor. The signalling unit is so organized that it may process simultaneously 96 instructions controlling as many different operations in a selected exchange (supermultiplex of 192 channels). Three different types of instructions are provided. These instructions may be grouped into programs capable of controlling the functions of a telephone central exchange. The instructions are as follows: 1. INSTRUCTIONS WHICH CONTROL A DATA TRANSFER BETWEEN THE SIGNALLING UNIT AND ONE JUNCTOR, 2. Instructions which control the supervision of the line and establish the digit analysis and the digit transmission, and 3. Instructions which control the switching network path check.
