TIS-B anonymous address I could not understand what is the difference between ADS-R with anonymous address (CF=6, IMF=1) and TIS-B CF=5, which on ICAO Doc 9871 is described,

for Version 1 as:


  Fine TIS-B Message AA field contains a non-ICAO 24-bit address


and for Version 2 as:


  TIS-B messages that relay ADS-B Messages using anonymous 24-bit
  addresses


Any specific example when CF=5 is used?

Thanks!
My question was due to the confusing mention of ADS-B in what was supposed to be either TIS-B or ADS-R.

I've now confirmed that the text on ICAO Doc 9871 Version 2 I quoted was due to a error.

In fact DO-260B, and even Doc 9871 Version 2 at table C-37 specify that TIS-B CF=4 is "Fine TIS-B message, AA field contains a 24-bit anonymous aircraft address".

ICAO e-mailed me confirming that this has been fixed into their working document.
