<span style=" font-size:10pt;font-family:sans-serif">Dear colleagues,</span>
<br><span style=" font-size:10pt;font-family:sans-serif"> Marie and
I reviewed the DVB-S2 BB document for checking correct implementation of
dispositions.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">However, after
careful review, we realised that RID ESA-AM-01, accepted during the review,
was actually causing a technical discrepancy.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">For your convenience,
I remind you that the RID was asking for removing the entry "Unmodulated"
under the MODCOD table in ANNEX D with the rationale that an unmodulated
signal is not a DVB-S2 signal but rather an operational use of the transmitter.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">In reality, we
realised that the term unmodulated refers to a DUMMY PLFRAME as specified
in DVB-S2, Section 5.5.1, that is nothing else than a PLHEADER + 36x90
symbols with I=Q=1/sqrt(2). (see screenshot below)</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Hence our proposal
would be to change the ESA-AM-01 disposition and the BB as provided in
attachment. (i.e., keep Unmodulated but add a note for clarification)</span>
<br>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Could you please
let me know if there is any opposition to this approach by <u>no later
than 15th September 2021 (EOB)</u>?</span>
<br>
<br>
<br>
<br>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Kind Regards</span>
<br>
