The field of telecommunication is no doubt one of the most exciting occupational fields that modern society has to offer. New technology is constantly being developed and finds its applications in the technical systems that make up a telecommunications network. This creates opportunities for developing existing services further, and introducing completely new ones - for the benefit of customers and society as a whole. The telecommunication industry is often referred to as an "enabling industry". That is, it creates opportunities for societal development in the broadest sense.

    As with all inventions, the road had not been smooth. For years, Graham Bell (as he liked to be called) had been experimenting with a harmonic telegraph. It should be possible, he reasoned, to send six tones over the same wire at the same time and cause six reeds attached to the receiving end to be operated. Furthermore, if all worked well, varied combinations of these six pitches could reproduce human speech.
