Binary Signal Transmission via Synchronous Leased Line with G703.1/X.21 Connection
The application shows the optical connection of an I/O mirror to a communication converter (KU-XG) 7XV5662-
0AA01, which establishes a connection to a multiplexer with G703.1 interface (64 kbit/s) or X.21 interface
(64 kbit/s up to 512 kbit/s).
Transmission between the binary signal transmission with the KU-XG takes place interference-free via
62.5
μ
m/125
μ
m multimode fiber optic cable. The fiber-optic cables are prepared with ST plugs. The electric
G703.1 or X.21 connection to multiplexer takes place via short distances.
KU-XG has a wide-range power supply unit DC 24 V up to 250 V and AC 115 V/AC 230 V.
The asynchronous baud rate of the binary signal transmission depends on the available synchronous band
width of the transmission route. This also essentially influences transmission time.
A maximum of 6 binary single signals can be transmitted bidirectionally.
