Procedure for switching digital signals.

THIS PROCEDURE IN CONNECTION SIGNAL (DS) IN A DIGITAL HIERARCHY (SDH) or Synchronous Digital Hierarchy (PDH) DIGITAL PDH, digital signals are within structures INSERTS (PR1) PULSE OF BASE DSM. THIS STRUCTURE CONSISTS IMPULSE 9 lines (Z) Y 100 COLUMNS (S). THE WORDS OF DATA TRANSMITTED DSM UNDERSTAND EACH ONE BIT 9, of which 8 BITS OF INFORMATION FOR SIGNIFICANT AND A BIT FOR ADDITIONAL DATA. By interlacing of various structures (PR1) IMPULSE DSM, STRUCTURES CAN BE CAUSED (PRN) PULSE OF HIGHER ORDER DSM-N.
