<p class="MsoNormal"><span style="font-size:12.0pt">Recommendations:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Definition of PLCW and CLCW should be removed from Proximity-1 SDLP and TC SDLP, respectively; both data units should be specified in a new document (their application being not limited to COPs).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Callout of PLCW should be changed from "Proximity Link Control Word" to "Protocol Link Control Word" (just as CLCW was changed from "Command Link Control Word" to "Communications Link Control Word" to make
it not specific to TC).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">Rationale: If USLP is ever going to replace existing protocols, it can’t be reliant on them.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;color:#1F497D">In addition, Tom thinks an argument could be made for vaguely categorizing CLCW/PLCW/SPDU as denizens of Layer-5 to justify moving their definitions en masse into the new session-control book.</span><span style="font-size:12.0pt"><o:p></o:p></span></p>
