Competition and Deployment of New Technology in U.S. Telecommunications Howard A. Shelanskit Participants in regulatory and antitrust proceedings affect- ing telecommunications have, with increasing frequency, asserted that policy decisions designed to promote or preserve competition will have unintended, negative consequences for technological change.1 The goal of this study is to determine the initial pre- sumption with which regulators and enforcement agencies should approach such contentions. To that end, this Article examines how the introduction of new technology in U.S. telecommunica- tions networks has historically related to market structure. It analyzes deployment data from a sample of technologies and finds that innovations have been more rapidly deployed in tele- communications networks the more competitive have been the markets in which those networks operated. This positive correla- tion between competition and adoption of new technology sug- gests that regulators and enforcement officials should be wary of claims that, by adhering to policies designed to preserve competi- tion, they will impede firms from deploying innovations or bringing new services to consumers.2 f School of Law, University of California at Berkeley. -
Listing of Various Vintage Switching, Telecom, and Teletype Tools, Part 1
C.O. and Strowger Switch/Other Telecom Tools Part 1 Etelco BT The following are some of the tools in the collection of the Telephone Museum of P.E.I. - they are not for sale. I am posting this on the site, as it provides a good listing of the tools available from each manufacturer, plus descriptions of the designed usage from the manufacturer's catalogs. This is by no means a complete listing of all tools manufactured and used in the telecom industry. There was a specialty tool designed for just about every job. You may note some items marked as not yet received. These are items on order, or that are in the mail to me. I am continually looking for tools to add to this collection - Dave Hunter, [email protected]: I have only listed a few of the Butt sets in the collection. I have 20-30 in the collection, but have only listed a few of the more common types. I have a number which were conversions of non-dial butt sets which have had dial shrouds added as well. The early items I put on this list do not have accompanying photos. Recent additions do have photos, and as I get time, I will gradually re-vamp the listing to include photos for all items listed.

“Mr. Watson- Come Here- I Want to See You!” These Were the First Words Ever Spoken on a Telephone by Inventor, Alexander Graham Bell on March 10, 1876
“Mr. Watson- Come here- I want to see you!” These were the first words ever spoken on a telephone by inventor, Alexander Graham Bell on March 10, 1876. Many people do not know that the telephone was also being invented at the same time by two other individuals. With only hours separating the two inventors, Alexander Graham Bell patented the device before competitor Elisha Gray could file for his patent. Through the invention of the telephone other technological inventions have been able to be created such as the internet, fax machines, and cellular phones. With the ever-changing habits of communication, the telephone has allowed the transformation of technology to adapt to the ever-increasing needs of the consumer. Wall Mounted Phones Wood Wall phones were among the first phones that were made available to the public by the early telephone companies of the late 1900s. Most of these phones had self contained batteries to provide transmission power, and a magneto to generate the electricity required to ring the bells of the party being called. This strategy enabled telephone users to communicate with each other without the requirement for a centralized power supply. An added benefit was derived from the fact that the local batteries provided a stronger more consistent power source compared to common battery power that suffered from line attenuation in the extended line runs common in rural settings. The manufacture of local battery phones with magneto ringing was essentially This wood wall phone was manufactured discontinued in the US during the 1940s. The rural nature of Canada, however, created an by the Century Telephone Construction ongoing need for these phones. -

THE BELL SYSTEM TECHNICAL JOURNAL volume xxxvii March 1958 number2 Copyright 195S, American Telephone and Telegraph Company Telephone By E. T. GREEN This article, which appeared in the 1957 printing of the Encyclopedia Brilannica* has been reprinted by special permission for readers of the Bell System Technical Journal. All statistics have been corrected to the latest available figures. An objective account of the invention of the telephone itself is given, and the subsequent development and growth of telephony are described. A statisti- cal summary is presented of the intensity of development in different parts of the world. This is followed by a comprehensive review of technical develop- nients, including progress in station instrumentalities, and transmission and switching principles and methods. The article concludes with a predic- tion of trends to he anticipated in telephony as a result of recent technical advances. The term 'Telephone" (from the Greek roots rfjXe, far, and (puvh, sound) was formerly used to describe any apparatus for conveying sounds to a distant point. Specifically, the word was applied as early as 1796 to a megaphone, and not long afterward to a speaking tube. Subse- quently the name "string telephone" was given to the device invented long before by Robert Hooke (1607), in which vibrations in a diaphragm caused by voice or sound waves are transmitted mechanically along a string or wire to a similar diaphragm which reproduces the sound. Still later, devices employing electric currents to reproduce at a distance the mere pitch of musical sounds were called telephones. Nowadays, how- ever, this name is assigned almost exclusively to apparatus for reproduc- * Copyright 1957 by Encyclopedia Britaonica 2S9 290 THE BELL SYSTEM TECHNICAL JOURNAL, MARCH 1958 ing articulate speech and other sounds at a distance through the medium, of electric waves. -
