<font size=2 face="sans-serif">Dear CSTS Colleagues,</font>
<br><font size=2 face="sans-serif">Please find on our CWE the RCF Book
Wolfgang updated for USLP support:</font>
<br><a href="https://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/SLE%20Services/RCF%20for%20USLP.doc?Web=1"><font size=2 color=blue face="sans-serif">https://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/SLE%20Services/RCF%20for%20USLP.doc?Web=1</font></a>
<br>
<br><font size=2 face="sans-serif">Please review the changes until our
subject meeting on 16th of July. In particular Wolfgang has raised these
questions:</font>
<br>
<ul>
<li><font size=3>Shall the RCF service also in case of USLP be limited
to the delivery of a Master Channel or a Virtual Channel? As the TC space
link protocol USLP supports the notion of MAP channels. The attached version
of RCF would not support the selection of a MAP channel. Shall delivery
of a MAP channel be a separate service given that only for USLP frames
such selection would be feasible. Also, there is no MAP frame counter and
consequently reporting of gaps in the stream of MAP channel frames is not
possible while we report such gaps for the frame stream of a VC channel.</font>
<li><font size=3>RCF reports the frame-sync-lock-status. For the case of
variable length USLP frames this parameter does not make sense. Shall we
simply specify that this parameter is set 'unknown' when variable length
USLP frames are to be delivered?</font></ul>
<br><font size=2 face="sans-serif">Looking forward talking to you in July.</font>
<br>
<br><font size=2 face="sans-serif">Best regards,</font>
