[Sls-slp] Draft Modification to USLP if VLFs defined in 131.0 (TM sync & cc) etc are allowed

[Kazz, Greg J (US 312B)]

Dear SLP WG,

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.

I clarified the two cases:

  1.  the use case for fixed length frames without slicing the data stream
  2.  the use case for variable length frames including slicing the data stream

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.

The URL of that document (with Oct 26 in the filename) is:

Of course, the final text will be dependent upon your review as well as the actual changes to 131.0, 131.2, and 131.3 by the C&S WG.

I’m particularly keen on hearing back from the C&S WG members on this thread as well.

Thanks much,
Greg
