 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><span lang="FR"><o:p></o:p></span></p>

 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><span lang="FR"><o:p></o:p></span></p>
