They have, however, a unique con®guration of zero and one bits which are interpreted as the syn character. Once a group of syn characters is transmitted, the receiver recognizes and synchronizes itself onto a stream of those syn characters. 21 Synchronous transmission. In synchronous transmission, one or more syn characters are transmitted to establish clocking prior to the transmission of data After synchronization is achieved, the actual data transmission can proceed. 21. In synchronous transmission, characters are grouped or blocked into groups of characters, requiring a buffer or memory area so characters can be grouped together.
Asynchronous transmission normally is used for transmission at speeds at or under 33 600 bps over the switched telephone network or on leased lines, while data rates up to 115 200 bps are possible over a direct connect cable whose distance is normally limited to approximately 50 feet. The term asynchronous TTY, or TTY compatible, refers to the asynchronous start±stop protocol employed originally by Teletype1 terminals and is the protocol where data are transmitted on a line-by-line basis between a terminal device and a mainframe computer.
Top: the term half-duplex terminal mode implies that data transmitted is also printed on the local terminal. This is known as local copy. Bottom: the term full-duplex terminal mode implies that no local copy is provided 26 _______________________________ FUNDAMENTAL WIDE AREA NETWORKING CONCEPTS software program they are using. Thus, the term `echo on' during the initialization of a communications software program would refer to the process of displaying each character on the user's screen as it is transmitted.
