virtually every arpa director, and most arpa personnel at all levels, have encountered friendly and not-so-friendly "why arpa?" and " what is arpa?" questions throughout its history. this report seeks to explain some of the "whys" and "whats." | Barber Associates, Richard J.: The Advanced Research Projects Agency 1958-1974, report prepared for the Advanced Projects Research Agency under contract MDA 903-74-C-0096.

UK Post Office: 800bit/s, 3.2, 12.8 and 64kbit/s USA AT&T: 2.4, 4.8, 9.6, 48 and 56kbit/s (costumer data rates) French PTT: 800bit/s, 3.2, 12.8, 64kbit/s Switzerland proposed 160kbit/s

all of them seemed to agree in regard to multiplexing that 64bit/s should be standardized. While AT&T would use the same multiplexing techniques for national and international use, the british post office made a difference between national and international channels ...
