I think the correct phrase needs to be something like "Radio Biterr Rate Data Item is a mandatory TLV containing the chance (independently) for each bit to be changed in transmission. If you multiply the frame size (in bits) with the inverse biterror rate, you get the average number of changed bits in the frame." > == > question -- > > The rate here is as a percentage of bits transmitted rather than time period, > correct? The text seems to imply per time period in some way, but I'm pretty > certain it's actually per bit recieved in this case? Good catch... I have to make sure to explicitly state that we are talking about measurements (Biterror, SNR, ...) of incoming transmissions... > == > question -- > > The format of the Radio Biterror Rate Data Item is ... > The format of the Radio SNR Data Item is ... > The format of the Radio Signal Strength Data Item is ... > The format of the Radio Noise Data Item is ... > > Do these need length fields? It doesn't seem to adding any information? They are part of the way DLEP transmits parts of DLEP messages... see https://datatracker.ietf.org/doc/html/rfc8175#section-11.3 for more information.
