<p>Thanks, Peter. I think we will make faster progress with a webex
meeting rather than email. I would like to resolve each of the six

<p class="MsoNormal">Hi Jon and all our other SLS C&S and
RFM WG colleagues.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the context of the Space Communication
Cross Support (SCCS) Architecture Requirements Document (ARD)
we have this on-going discussion of the state of the SLS “VCM
Suite” of variable coding and modulation standards. Jon has
pointed out, at length, that there is no term “VCM suite”
defined within the C&S WG or within any of the SLS Area
literature. I have to agree that this statement, taken by
itself, is true.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What Jon has then requested is that this
term “VCM Suite”, and the diagram we have constructed to
explain the complexities of this situation, be replaced in the
SCCS-ARD by the single term “the VCM protocol” and also be
shown as three separate boxes in figure 6-1, Layering of CCSDS
link layer protocols. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Last week we held a 2 hour review of all of
the major changes we have introduced in the SCCS-ARD. These
changes are due to the usual 5 year document review and the
addition of many new standards, several of which had only been
forecast in the original edition. Among these were the DVB-S2
(CCSDS 131.1-B-2), the SCCC (CCSDS 131.2-B-2), and the VCM
(CCSDS 431.1-B-1). What cannot be in question is that all
three of these describe themselves as “VCM protocols”. Even
the 431.1 document describes all three of these, separately,
as VCM protocols.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">See the two attachments for screen shots of
the 431.1 document where these statements are made and where
some of the differences are described, in text.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The 431.1-B-1 document also makes this
statement, in Sec 1.2 Purpose and Scope<o:p></o:p></p>
<p class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in"><span
style="font-size:12.0pt;font-family:"TimesNewRomanPSMT",serif;color:#0070C0">The
purpose of this Recommended Standard is to specify various
combinations of coding and modulations in references [1],
[2], [4], and [5], that can operate under the VCM protocol
defined in references [2] and [4]. This enables, for
example, some of the CCSDS recommended channel codes
(reference [1]) and modulations (reference [5]) to be used
with the CCSDS VCM protocol.
</span><span style="color:#0070C0"><o:p></o:p></span></p>
<p class="MsoNormal">In reading through this 431.1-B-1 document,
again, I am struck fact that the document, in two different
sentences, says “there are three different VCM protocols”, and
then “there is one ‘CCSDS VCM protocol’”. Just looking again
at these documents, all three of them, three things are very
clear:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" type="1" start="1">
<li class="MsoListParagraph"
style="margin-left:0in;mso-list:l1 level1 lfo4">There are
three separate documents, each of which is defined as a “VCM
protocol”.<o:p></o:p></li>
<li class="MsoListParagraph"
style="margin-left:0in;mso-list:l1 level1 lfo4">The three
are similar, but, in detailed fact, are different and cannot
interoperate.<o:p></o:p></li>
<li class="MsoListParagraph"
style="margin-left:0in;mso-list:l1 level1 lfo4">The third of
these, CCSDS 431.1 cannot stand alone, it is meaningless
without heavy reliance on major parts of DVB-S2 and SCCC,
which it terms as Type 1 and Type 2 VCM schemes.<o:p></o:p></li>
</ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am not going to un-Earth the history of
how we got into this situation, but I firmly believe that if
we asked any knowledgeable, independent, reviewer with
relevant technical background to review these three standards
they would ask “Why do you have three nearly identical
standards when one would do?”. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But the facts are that we do have two
nearly identical standards and a third one that could not
exist at all without the other two, which it is (almost)
entirely dependent upon. This is unique in CCSDS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As for SCCS-ARD, the attached PPT file will
make clear how we propose to handle this situation. Instead
of showing the Telemetry S&C, and the Telecommand S&C,
and three separate, different, but admittedly nearly
identical, VCM protocols, we have chosen to call this set of
triplets the “VCM suite”, to show how these fit with the other
related standards, and to show their similarities and
differences. We think that this both provides visibility to
this VCM technique, allows us to state what value they bring
(primarily for high rate downlink missions), and also to not
overly complicate an already complicated diagram with three
essentially identical VCM protocols.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We called this trio of VCM standards the
“VCM suite”. If you all have a better name to suggest we are
open to hearing it. All of the other people we have had
review this agree that this is a suitably simple, and
effective, way to deal with this complicated situation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If we need to have a WebEx to discuss this
I am more than willing to set one up.<o:p></o:p></p>

<p>Thank you for the invitation to review the SCCS-ARD. I regret
that I will not be able to discuss the SCCS-ARD in person on
23 Nov. I will be on vacation that week. I give my comments
here, with the hope that this is enough in advance of the
meeting for each of the individual comments to be read and
discussed at the meeting.<o:p></o:p></p>
<p>My primary comment is that updating the SCCS-ARD is clearly a
large undertaking, and I would like to congratulate John
Pietras and Peter Shames for on the production of a quality
document. It is difficult to absorb such a large swath of
CCSDS standards and integrate them into a helpful summary of
the interfaces as this SCCS-ARD does.<o:p></o:p></p>
<p>My other comments primarily relate to the new VCM content.
There are six main comments, with more detailed description,
recommendation, and justification for each. These comments are
written based on the latest SCCS-ARD, but I also repeat
portions of my June-23 comments if they were not yet
addressed. I believe the SCCS-ARD will be much improved if we
adopt these recommendations.<o:p></o:p></p>

CCSDS does not have a "VCM suite" and I think it is
a mistake to invent this new concept here,
especially since it would risk confusing the reader
into thinking that there is more than one VCM

131.2 and 131.3 are not members of a supposed "VCM
suite." They are not even the same kind of thing
that 431.1 is. 431.1 is a protocol book, while 131.2
and 131.3 describes codes, modulation, and VCM.<o:p></o:p></li>
<li class="MsoNormal"

One VCM protocol. As we worked out in the C&S
and RFM WGs at the time we negotiated the VCM
protocol blue book (431.1-B-1), there is one VCM
protocol that can be used with multiple sets of
codes and modulations described in other blue books.
There are some variations and options in this
protocol, but it is fundamentally one protocol that
operates in the same way, namely, with a header
signaled with pi/2-BPSK and protected with a
specific RM code, followed by code symbols using a
higher order modulation. This is why the VCM blue
book has the title "Variable Coded Modulation
Protocol" with no plural word or "suite."

<li class="MsoNormal"
style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0

In other words, the protocol is singular. What is
plural is the set of VCM tables that can be used in
conjunction with the protocol. Incidentally, in
other areas CCSDS doesn't refer to a "code suite,"
or a "ranging suite" or a "frequencies suite" where
there are clearly multiple options. <o:p></o:p></li>

As we know, there are 4 CCSDS coding standards
that ingest TM/AOS/USLP frames (what we might
previously call space-to-ground links): 131.0
(turbo/LDPC), 131.2 (SCCC), 131.3 (DVB-S2 LDPC),
and 142.1 (SCPPM). These references should
appear together in Table 6-1 in the same way,
not with 131.0 in its own row and 131.2 and
131.3 relegated to a secondary category within
"VCM suite." The SCCS-ARD should be about
interfaces (in this case, ingestion of TM, AOS,
or USLP Transfer Frames). Treating them
differently in the table doesn't make sense. <o:p></o:p></li>
<li class="MsoNormal"

In particular, Table 6-1 as written calls out
142.1 and 131.0 as "coding" books and 131.2 and
131.3 as members of a supposed "VCM suite." But
131.2 and 131.3 are primarily about the codes
they define -- the SCCC codes and DVB-S2 LDPC
codes. When C&S negotiated their acceptance,
the discussion was primarily about the coding
performance, complexity, maturity, etc., and not
their associated VCM approaches (which are

The duplication mentioned above may confuse a

Few of the salient features of the VCM protocol
are actually present in the figure. The VCM
header is transmitted with pi/2-BPSK modulation,
for example. The pilots are optional. The header
has two parts, a sync marker and a signaling
structure (PLS or frame descriptor). The frame
descriptor is protected with a (32,6) code. All
of that is missing.

<p style="margin:0in">The Space Communications Cross Support
Architecture document (SCCS-ARD) is a cross-cutting Magenta
Book that largely covers the SLS, SIS, CSS, and SEA areas
and their working groups. We have being working on an
update to this document that primarily covers what are
called “ABA” mission configurations, which are those that
involve a single mission ops center, a single spacecraft,
and a ground station. The Solar System Internet (SSI)
configurations, which involve multiple spacecraft, mission
centers, and comm assets, and use the DTN (or IP) protocols,
will be in a future update that builds on this foundation.<o:p></o:p></p>
