[Sls-slp] Does SDLS apply to USLP truncated transfer frame ?

[Kazz, Greg J (US 312B)]

Dear Gilles and SLDS WG,

SLP WG has a question regarding the application of the SDLS protocol to truncated USLP Transfer Frames.
These truncated frames are envisioned for very short length telecommands or forward link Proximity-1 link commanding. This frame type provides backward compatibility with TC hardware commands or immediate commands. These commands are typically 2 octets long. We envision the truncated USLP frame length to be between 8 and 32 octets.
In that context, does it make sense for SDLS header and possibly SDLS trailer to apply to the USLP truncated frame.

The discussion of the proposed non-use of SDLS for truncated USLP frames is mentioned in Chapter 6, specifically  in Section 6.3.2. The definition of the truncated USLP frame is in Annex G of the attached draft document

The SLP WG did not think SDLS should be applicable to truncated USLP frames, but we would like your opinion on this matter.

Best regards,
Greg Kazz
Chair SLP WG
