Editing ITT Inc. (section)

=== International telecommunications ===
International telecommunications manufacturing subsidiaries included [[Standard Telephones and Cables]] in the United Kingdom and Australia, [[Indosat]] in Indonesia, [[Standard Elektrik Lorenz]] (today part of [[Nokia]] Germany) and ''{{interlanguage link|vertical-align=sup|Intermetall|de}} Gesellschaft für Metallurgie und Elektronik mbH'' (acquired from [[Clevite]] in 1965; now TDK-Micronas) in Germany, [[Bell Telephone Manufacturing Company|BTM]] in Belgium, and CGCT and LMT in France. These companies manufactured equipment according to ITT designs including the (1960s) Pentaconta [[crossbar switch]] and (1970s) Metaconta D, L and 10c [[Stored Program Control exchange]]s, mostly for sale to their respective national telephone administrations. This equipment was also produced under license in [[Poznań]] (Poland), and in [[Socialist Federal Republic of Yugoslavia|Yugoslavia]] and elsewhere. ITT was the largest owner of the [[LM Ericsson]] company in Sweden, but sold out in 1960.

[[Alec Reeves]], an ITT employee in France in the 1930s, developed [[pulse-code modulation]] (PCM) innovations, upon which future digital voice-communication was based. [[Charles K. Kao]], working at STC in the UK, pioneered the use of [[optical fiber]] from 1966, for which he was awarded the 2009 [[Nobel Prize in Physics]].
