<font size=2 face="sans-serif">Greg,</font>
<br><font size=2 face="sans-serif"> the
approach of some proposed modifications seems to be extending the Frame
Sublayer of Proximity-1 to be able to generate USLP Frames.</font>
<br><font size=2 face="sans-serif">This may (might?) introduce some conflicts
for over specification and an alternative approach may be introducing informative
changes that the Frame Sublayer of Proximity-1 may be replaced
by the USLP Space Data Link Protocol as specified in the USLP Blue Book.</font>
<br><font size=2 face="sans-serif">I think this could be managed with a
Corrigendum (most likely Technical and not simply Editorial) once USLP
is published.</font>
<br>
<br><font size=2 face="sans-serif">The WG (and Tom) may explore this alternative
approach.</font>
<br>
<br><font size=2 face="sans-serif">Regards</font>

<br><font size=2 face="Calibri">Dear SLP WG,</font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">There will be a need to slightly modify
the CCSDS Proximity-1 Space Data Link Protocol (CCSDS 211.0-B-5) dated
Dec 2013, in order to accommodate the use of the Version-4 Transfer Frame
(defined in USLP) over the proximity link. </font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">These changes involve the optional use
of the Version-4 (USLP) Transfer Frame format over the proximity link.</font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">Please review my draft changes to the Prox-1
Space Data Link Protocol Blue Book (which you can now find on the CWE at
the URL below) and send me your comments and any additional updates you
feel are required that I may have missed.</font>

<br><font size=2 face="Calibri"><b> </b></font>
<br><font size=2 face="Calibri">My goal is to incorporate any comments
or changes you may have into the next version, that we need to discuss
at the Fall 2017 meeting in the Hague, so that we can come to consensus
there on the actual Pink sheets to be send to agency review directly thereafter.</font>
<br><font size=2 face="Calibri"> </font>
<br><font size=2 face="Calibri">Please note that we have already discussed
and have agreement with the C&S WG concerning the set of pink sheets
to the Proximity-1 Coding & Synchronization Sublayer Blue Book (CCSDS
211.2-B-2) which allows the Version-4 frame in the C&S sublayer.</font>
