Abstract

In einem STM-4-Pulsrahmen der Synchronen Digitalen Hierarchie SDH werden im Overhead in der 2, 3, 6, 7 und 8ten Zeile Kontrollbytes eingefügt, die 5 Codierungsabschnitte (BLOCK 1 bis BLOCK 5) zugeordnet sind. Der verwendete BCH-Code kann 2 Fehler korrigieren. Durch die Fehlerkorrektur wird die Restfehlerrate wesentlich verringert, ohne daß hierfür die Payload eingeschränkt wird oder eine Erhöhung der Übertragungsrate erforderlich ist.
