Synchrone Datenübertragung (HDLC,
HDLC NRZI)
Bei der synchronen Übertragung
erhält nicht jedes Zeichen
Synchronisationsinformationen,
sondern ganze Zeichenfolgen bilden
einen Block. Das vergrössert die zu
übertragende Datenmenge
wesentlich und ein höherer
Durchsatz resultiert. Auch die
synchrone Datenübertragung kommt
nicht ohne Zusatzinformationen aus.
Wie bei der asynchronen
Übertragung fügt man Steuerzeichen
ein, welche eine Synchronisation
und die Aufschlüsselung der
jeweiligen Blöcke ermöglichen. Die
synchrone Übertragung benötigt
ausserdem ein Taktsignal, welches
die Übertragungsgeschwindigkeit
vorgibt.
Diverse synchrone Übertragungs-
protokolle sind bekannt, vor allem
HDLC und HDLC NRZI. Um den TA
mit synchroner Datenübertragung
am PC zu betreiben, ist eine speziell
darauf ausgelegte Karte, mit einer
zugehörigen Software, erforderlich.
Hinweis:
Leitungen Transmitter Clock (TD,
CCITT 114) und Receiver Clock (RC,
CCITT 115) sind nur bei synchroner
Datenübertragung in Gebrauch.
