	Bell System Technical Journal
		This is economically significant in the Bell System toll plant, where an average of 1.4 transmission links comprise a trunk.
		In-band signaling systems tend to be more complex because of the need for protection against speech-generated signals, but the Bell System type of in-band signaling provides protection adequately and economically by signal-to-guard arrangements in the signaling receiver.
		Present standard voice-frequency signaling systems employ tones of 1600 to 2600 cycles and use all frequencies, except the signaling frequency, to guard against false operation of the signaling receiver on speech currents.

	Bell Labs: A Brief Introduction
		Foremost among them was the development of the UNIX operating system, which, along with the transistor, is often considered to be one of the two greatest inventions to come out of Bell Labs.
		The C programming language, which was written at Bell Labs in the early 1970s chiefly by Dennis Ritchie, is in many ways the most important of the hundreds of programming languages that have been developed in the world to date.
		Bell Labs' main facility consists of a vast complex of buildings located in the tranquil-looking town of Murray Hill, New Jersey, which is about 20 miles west of New York City.

	A Mathematical Theory of Communication
		Claude Shannon's ``A mathematical theory of communication'' was first published in two parts in the July and October 1948 editions of the Bell System Technical Journal [1].
		The text of the latter is a reproduction from the Bell Telephone System Technical Publications, a series of monographs by engineers and scientists of the Bell System published in the BSTJ and elsewhere.
		Prefaced by Warren Weaver's introduction, ``Recent contributions to the mathematical theory of communication,'' the paper was included in The Mathematical Theory of Communication, published by the University of Illinois Press in 1949 [4].

		A Bell Labs chairman described him as “a person of limited patience, for he often regarded patience as an obstacle to action.” And an ATandT board chairman recalled that “Mervin was always and forever pushing the operating management, and the heads of ATandT as well, to get on with new things.
		The Bell System belonged to its stockholders, and though ATandT was a prime investment, no entrepreneur could hope to own a significant portion of the company.
		In addition, Bell scientists had to sign all patent rights to their inventions over to the company; in Silicon Valley, on the other hand, scientists launching a start-up could enjoy both corporate ownership and patent rights.

		The cost of such a system would be high, Pierce estimated it at $500 million in his 1961 article, but that was not a detriment from AT&T's standpoint.
		The costs of the satellite system would be passed on to consumers just as the high costs of undersea cables were.
		Bell Labs had developed much of the technology required for satellite communcations including transistors, solar cells, and TWT amplifiers.

		When Bell Labs realized its mistake, they quickly pulled as many copies of the journal in question as they could, but it was a futile effort.
		While some saw it as tools that should be used for purely technical means, namely exploring the growing network of telephones and computers, others saw it as a way to strike a blow against the telephone company, which was seen by some as a greedy, inefficient monopoly.
		Faced with the difficult lifestyle of prison, their technical skills were their only means of survival; they were forced to hold classes on phreaking and hacking in order to ensure their safety.

	The Beginnings of ``Information Theory"
		Publishing in the same journal as Nyquist, the Bell System Technical Journal, and yet not citing Nyquist (or any one else, for that matter), Hartley developed the concept of information based on ``physical as contrasted with psychological considerations" for use in studying electronic communications.
		Hartley was aware of a relationship between the amount of energy in an information system and the amount of information that could be transmitted.
		Shannon describes a communication system, while the more general hierarchical model can encompass communication, observation, and, in fact, any process that can produce a change in the universe.

		NASA was able to claim Telstar as a NASA supported project and even publish the report on the results of experimentation as a NASA publication (SP-32, a reprint of the Bell System Technical Journal articles about the project), as well as getting rights to any patentable inventions arising from the experiments.
		To achieve the early establishment of a communication satellite system which can be used on a commercial basis is a national objective which will require the concerted capabilities and funds of both Government and private enterprise and the cooperative participation of communications organizations in foreign countries.

		A quick reading of Harry Nyquist's classic Bell System Technical Journal article of 1924 (Reference 1) does not reveal the true significance of the criterion which bears his name.
		The system shown in Figure 1 is a real-time system, i.e., the signal to the ADC is continuously sampled at a rate equal to f
		Finally, there are slower speed industrial process control systems where sampling rates are much lower–regardless of the system, the fundamentals of sampling theory still apply.

	THE BELL SYSTEM
		One of the chief advantages of the use of the vacuum tube to sustain oscillations in a mechanical system is that the variable friction of the contact mechanism is avoided.
		As already discussed in relation to the pendulum, the amount that the rate of oscillation may be disturbed in a given structure is proportional to this energy and, to first order, on the departure from the ideal phase condition of the applied driving force.
		The early scaling circuits operated on the binary system, but recently various circuits have been developed that give the count in scale-of-ten notation with certain advantages, chiefly that of convenience, associated with the common decimal system of notation.

		Performance of this new transistor is described in technical articles published in the July issues of the Bell System Technical Journal, the Physical Review, and the Proceedings of the Institute of Radio Engineers.

		At the time, MIT was one of a number of prestigious institutions conducting research that would eventually formulate the basis for what is now known as the information sciences.
		In 1941, Shannon joined the Bell Telephone Laboratories, where he became a member of a group of scientists charged with the tasks of developing more efficient information transmitting methods and improving the reliability of long-distance telephone and telegraph lines.
		He applied his earlier research to the problem at hand, again using Boolean logic to develop a model that reduced information to its most simple form--a binary system of yes/no choices, which could be presented by a 1/0 binary code.
