|ftth and P2V,|
Good Stuff, indeed, from both of you. Thanks for shining some light in a few places that have always intrigued me, but apparently not enough for me to get off my duff and do the necessary research to unravel it all.
The discussion concerning the methods of equalization used was also of special interest to me. I spent the better part of a year during the late sixties equalizing secure government data lines (using both active and passive r-c and r-l-c type equalizer units) between NYC and Goonhilly (UK), Raisting (GE), Etam, WV, Andover, ME. Pottstown, PA, where an underground spring-supported central office lay in hiding. There were patch-able sections of three different hot lines to Moscow among those facilities (whose primary contractors were the International Record Carriers: WU Intl., RCA Global and ITT Worldcom).
You see, it was a time of considerable drama during the first cold war, too, albeit, of a different blend than we have today (sans Twitter and twits:)
