<p class="MsoNormal"><o:p> </o:p></p>
<p>I put the HPE coding & sync layer and HPE phyiscal layer prototype test reports (Yellow Books) in CWE, under<o:p></o:p></p>
<p>SLS-OPT/CWE Private/Draft Documents/Blue Book Optical Comm HPE Coding and Synchronization<br>
SLS-OPT/CWE Private/Draft Documents/Blue Book Optical Comm HPE Physical Layer<o:p></o:p></p>
<p>The prototype testing revealed two minor editorial oversights in the proposed HPE coding standard.  This is described in the coding Yellow Book.  There was also a request to reword the way the physical layer frequencies are described in the HPE physical
 layer book.  (The allowed frequencies are the same; only the wording has been changed.)  These updates have also been uploaded to the same folders in CWE.<o:p></o:p></p>
<p>If everything is in order, I would like to request at the April 16 VITS for consensus for the working group to issue a resolution to proceed with publication of the HPE Blue Books.<o:p></o:p></p>
