<font size=2 face="sans-serif">Dear CSTS Colleagues,</font>
<br><font size=2 face="sans-serif">A preliminary version of the SLE PIDs
is on the CWE:</font>
<br><a href="https://cwe.ccsds.org/sls/docs/Forms/AllItems.aspx?RootFolder=/sls/docs/SLS%20Area/CESG%20Polls/2021-08%20SLE%20BBs&FolderCTID=0x012000439B56FF51847E41B5728F9730D7B55F&View=%7bAE8FB44C-E80A-42CF-8558-FB495ABB675F%7d"><font size=2 color=blue face="sans-serif">https://cwe.ccsds.org/sls/docs/Forms/AllItems.aspx?RootFolder=/sls/docs/SLS%20Area/CESG%20Polls/2021-08%20SLE%20BBs&FolderCTID=0x012000439B56FF51847E41B5728F9730D7B55F&View=%7bAE8FB44C-E80A-42CF-8558-FB495ABB675F%7d</font></a>
<br>
<br><font size=2 face="sans-serif">They are still prelimenary and not final.
But probably worth to have a look before our telecon next week to get an
idea. Glancing through, it seems mainly about the variable length frame
business on the downlink and the applicability of coding. Another topic
is scurity for the forward services, in particualar the Frame Security
Report which is a new OCF. Generally the PIDs are well described and make
concrete recommendations to solve the issues.</font>
<br>
<br><font size=2 face="sans-serif">Please have a look, such that we can
start the discussion how to address the PIDs in our telecon 22 of September.</font>
<br>
<br><font size=2 face="sans-serif">Best regards,</font>
