<span style=" font-size:10pt;font-family:sans-serif">Dear all,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">following the
deadline, I've received comments only from DLR (email from Tomaso de Cola,
06 June), that I copied herein for your convenience:</span>

Massimo,</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Calibri"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Calibri">Just
few comments from my side:</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Calibri"> </span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Symbol">·</span><span style=" font-size:11pt;color:#004080;font-family:Calibri">I
understand the project is about the extension of the present 131.3-B-1
to allow interworking of DVB-S2 with USLP and AOS. However, the description
refers only to USLP. Similarly, the description provided in Annex 2 points
only to USLP and generically about space-to-space and ground-to-space links.
I’d suggest to explicitly mention AOS too.</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Symbol">·
</span><span style=" font-size:11pt;color:#004080;font-family:Calibri">In
general from the purpose and the description of the project, it is not
fully clear to me which technical work is planned here. Is it just about
adding a chapter about specifying the codes (as I read from the description)?
As such I understand, that new codes other than those of the ETSI DVB-S2
specification will be considered in this new chapter. Then, I also read
that this new chapter will also specify the space link protocols. What
does it mean exactly? Apparently I see something more than just “editing
work”, probably requiring validation through interoperability testing
(i.e. with the typical 2 prototypes). Why isn’t it the case?</span></p>
<p style="margin-top:0px;margin-Bottom:0px"><span style=" font-size:11pt;color:#004080;font-family:Symbol">·
</span><span style=" font-size:11pt;color:#004080;font-family:Calibri">In
the section dedicated to the schedule, I read October 2019-October 2020,
i.e. 12 months. However, immediately below it is stated “time to complete
17 months”.</span></p>

you in advance for the clarifications/comments to my doubts.</span></p>
