DESCRIPTION OF THE IMPROVEMENTS MADE IN
COMMUNICATION CIRCUITS OVER THE LAST DECADE
1.
There was a time in the experience of many communicators when "any old
telephone line" would do, so long as they could talk over it. Those days
are rapidly disappearing.
In this age of high-speed computers and rising
speeds of transmission, such a simple approach to communication will not
suffice. Not only must the quality of circuits remain high; they must also
be conditioned to accept and transmit the various types of complex signals.
2.
Over the past decade our engineers have produced and delivered large
numbers of highly sophisticated devices for communication between stations.
However, the capability of the telephone facilities did not keep pace with
equipment developments.
The reason is largely economic: telephone
facilities already exist.
Why provide expensive duplication of existing
lines? Let us use the lines we already have.
3.
Now the circuit conditioner enters on the stage of communication
history.
As he plies his new trade he is able to make ordinary quality
telephone lines accept and transfer information at a higher rate than he
could ever have hoped for in the past.
