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?

That claim is rather dubious. First, there is the claim of 320,000 channels of telemetry, while one paragraph earlier it lists 13,000 sensors on board. There will be setpoints in addition to sensor data, but 20x as many?
The earlier 5L mission had 10,000 telemetry channels.
I found these specifications for the S-530 computer:
speed: 0.1 MIPS
RAM: 256 13-bit words
ROM: 8,192 20-bit words
components: hybrid ICs Tropa
design: NII AP
I don't see how a computer with these specs could possibly generate Gbits/s of data.
Speculation: the 9.6 Gbit/s is an estimate by US intelligence analysts who listened in on the launch. Maybe they got something wrong and their recordings were garbled for a reason other than excessive data volume.

I suspect this confuses "bandwidth available" with "bandwidth that can be used concurrently at any one time". It certainly could not be processed at that rate by the ground based systems, let alone on-board.
