ABSTRACT
The facsimile transmission has grown into the modern fax system and has become a viable telecommunication information exchange technique. In the modern context of telecommunications, the wireline connection is conceived via electrical conduction through a copper conductor or by optical transmission in a fiber. Optical fiber transmission is a state-of-the-art method used widely in high-speed telecommunication links. High-speed networks offering a desired quality of service and bandwidth on demand have become the target architectures in telecommunication. On the networking side, the introduction of digital telephony and the perpetual growth in local traffic warranted new interoffice transmission fusibilities. The success of analog voice telephony stems from the standardized interfaces and well-defined functional hierarchy. The teletypewriting-based wireless transmission was also developed during the 1930s through the 1940s using a short-wave radio frequency band. The transmissions pertinent to a ground-station are assigned specific uplink and downlink frequency bands within the allotted satellite bandwidth.
