On the Wikipedia page for Soviet N1, it says of the control system:
The telemetry system relayed data back at an estimated rate of 9.6 gigabytes per second on 320,000 channels on 14 frequencies. Commands could be sent to an ascending N1 at the same rate.
There was a source for that claim though, a book available on Google books. https://books.google.com/books?id=nVeY7vMCtOkC&pg=PA226#v=onepage&q&f=false
This send pretty unbelievable to me considering general technology of the time, and the similar page on the Saturn V mentions about 200 channels of telemetry and 2 or 3 different transmitting frequencies.
Does this make sense? If so, how was this achieved in the late 60s/early 70s?
