<p class="MsoNormal"><span lang="EN-US">Please review my 4 modifications to the USLP BB (searchable in Word, when you use the term “Modified by GK”, that will bring you to them), if 131.0 (TM Sync & CC), 131.2 (SCCC), and 131.3 (DVBS-2) are modified to include
Variable Length Frames (VLFs) when the data stream is sliced. <o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Currently in the USLP BB online, we exclusively consider USLP limited to fixed length frames (FLF) whenever 131.0 (TM Sync & CC), 131.2 (SCCC), and 131.3 (DVBS-2) are in use.<o:p></o:p></span></p>
