This is an approximation. The correct value is not exactly 123 us, it is for the longest PRP frame 123,36 us (6,168 ms), but without PRP it is 122,8 (6,144 ms). Let's put 6,168 ms. 19 Jan 18 final proposal 2018-02-28
Will be considered in edition 2 of TR90-4, what is already in process. 16 Nov 17 red
