Introduction
to Digital Transmission
Telephone
service has been one of the primary methods of communication in
the last half of the Twentieth Century. When computers began to
send data, they passed in through the telephone network by
converting it into analog signals. Technology has now shown it is
easier to create a network of digital transmission and convert the
voice signals to move them. In essence, the telephone companies
have become digital companies. This video training program
consists of almost 2 hours of video on 2 tapes and a student
manual and will get you started in the digital revolution.
