<p class="MsoNormal">Dear SLP WG,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">SLP WG and the C&S WG held a joint telecon today regarding the three issues listed below (taken from Massimo Bertinelli’s email):<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"-webkit-standard",serif;color:black"><br>
</span><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">- 1) introduction of OID random pattern</span><span style="font-size:13.5pt;font-family:"-webkit-standard",serif;color:black"> </span><span style="font-size:11.0pt;font-family:"-webkit-standard",serif;color:black"><br>
</span><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">- 2) possible alignment of terminology in the TC books regarding retransmission </span><span style="font-size:11.0pt;font-family:"-webkit-standard",serif;color:black"><br>
</span><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">- 3) additionally, SLP would like to discuss adding USLP to the TC coding book and assessing its impact (other books are mentioned in the presentation, but agreement on these ones
has already been reached)</span><span style="font-size:13.5pt;font-family:"-webkit-standard",serif;color:black"> </span><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Massimo will provide a short summary of the telecon minutes which I will share with you all, once I have received them.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">From the perspective of impact on the SLP WG, here are the take aways:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Concerning Item 1 above, SLP WG recommended that a mandatory OID random pattern be added as a proposal for pink sheets to agency review. Further details on the way forward will come from the C&S WG.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Concerning Item 2 above, no area consensus achieved on changing the term, “systematic retransmission” in the associated SLP WG blue book. Therefore that term will remain unchanged. However, in the proposal, the clarifications to the types
of telecommand frames used e.g., AD vs BC vs BD frames did achieve consensus within the SLP WG, so those changes will go forward. The revised word document containing those changes have been posted to the CWE at
<b><span style="font-size:11.0pt"><a href="https://tinyurl.com/sbdeh3w">https://tinyurl.com/sbdeh3w</a>
</span></b>with the date, Dec 5 in the filename.<o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal">Concerning Item 3 above, an action was taken by Matt Cosby and Greg Kazz to confirm with Wallace Tai about the actual CCSDS agency need for the use of USLP over the CCSDS 231.0 TC Sync & Channel Coding specification. As pointed out during
the telecon the CCSDS 732.1 USLP BB defines an interface to 231.0.<o:p></o:p></p>
