Abstract

Danas se sve više napušta analogni prijenos informacija i teži se digitalizaciji svih dijelova telekomunikacijske mreže. Osnova digitalnog prijenosa je vremensko multipleksiranje i PCM (Pulse code modulation). Od digitalnih sustava prijenosa prevladavaju PDH i SDH hijerarhija. Razvojem tehnologija mijenjaju se međusobne relacije, tako je proizvodnja poluvodičkih memorija i vremenskih komutacijskih blokova postala ekonomičnija od proizvodnje prostorne komutacije s logičkim elementima. Veću praktičnu primjenu našle su strukture TST (Time-Space-Time) i STS (Space-Time-Space) komutacije. I na kraju smo razmatrali probleme sinkronizacije PDH (Plesiochronous digital hierarchy) i SDH (Synchronous digital hierarchy) mreža.

Abstract (english)

Today, more and more, the analogue transmission of information is being abandoned and the digitization of all parts of the telecommunications network is intensifying. The basis for digital transmission is time multiplexing and pulse code modulation (PCM). PDH and SDH hierarchy prevail over digital transmission systems. By developing technologies, they change their relationships, so the production of semiconductor memories and time switching blocks becomes more economical than the production of spatial commutation with logical elements. More practical applications have been found in TST (Time-Space-Time) and STS (Space-Time-Space) structures. Finally, we have considered the problems of synchronizing PDH (Plesiochronous digital hierarchy) and SDH (Synchronous digital hierarchy) networks.
