PROCEDURE FOR THE VERIFICATION OF THE SWITCHING ELEMENTS OF A SPACE PHASE UNIT OF A COUPLING NETWORK OF A DIGITAL INSTALLATION OF TELECOMMUNICATIONS SWITCHING IN MULTIPLE MODE BY TIME DIVISION.

摘要

A MULTIPLEX TIME TELECOMMUNICATION INSTALLATION IN A TEST MODE IS GUIDED TO THE UNIT ENTRIES (MUXS0 UP TO MUX15) OF SPACE STAGES DURING A COMBINATION OF TEST BIT, WHERE A BIT SHOWS A BINARY VALUE AND THE REST OF BIT BINARY VALUES. EACH BIT IS TRANSCONED ONE BEHIND ANOTHER IN EACH OUTPUT (SLT0 TO SLT15). BELOW IS THE REPETITION OF PROCESSES WITH COORDINATION OF INVERTED TEST BIT. THE REPETITION OF THE PROCEDURE IS PERFORMED UNTIL A SINGULAR BIT OF ONE AND OF THE OTHER BINARY VALUES IN EACH OUTPUT HAS BEEN TRANSCONNED FROM EACH ENTRY. INSPECTION IS MADE ON THE OUTPUT SIDE IN THE APPEARANCE OF EXPECTED EXTENSION BIT COMBINATIONS.
