</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
That’s fine, but what do you propose we do with the existing inconsistency?
We have used two different terms to mean the exact same thing. In
one case (actually 4 cases) we call these two fields “MCID”, in the other
case we call the exact same two fields “SCID”. In your opinion
should we drop the term GSCID and use MCID everywhere, or should we bring
all of the protocols into line and adopt GSCID everywhere?</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
Or, probably the worst case, should we document this mistake we have made
so that it is clear that we have two terms for the same thing?</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
I’m asking you, in particular, because all of those protocol docs are
in your area. I’m also guessing that you will be resistant to changing
any of them, in which case the choice is likely to be “Keep MCID.” We
can do that, but then we will need to put something in the “GSCID doc”,
which should really in that case be called the “MCID doc”, that these
are actually one and the same.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
And I think, as I said, that we can call this field, concatenated with
the frequency bin, the “Extended GSCID” or E-GSCID (or E-MCID).</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
I’d like to get your opinion about this specific issue so I can include
it in the revised 320x0 that I submit for review.</font><font size=3 face="Times New Roman">

Dear Gippo,</font><font size=3 face="Times New Roman"> <br>
</font><font size=2 face="Calibri"><br>
In this case we seem to have a term, GSCID, defined in 320x0 that is used
only in that document and nowhere else. And we have the fields that
compose that term, the VN and SCID, defined in every other relevant document
as the MCID. The only exception to this, I have been informed, is
the new USLP which proposes to use the term GSCID instead of MCID.</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Calibri"><br>
In order to get this cleared up efficiently I propose that we use the term
MCID in the 320x0 document, thus fixing that obvious error, and that we
also bring the USLP in-line, before it sees the light of day.</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Calibri"><br>
At that point we can use the term GSCID as I proposed, without any risk
of confusing anyone, since no other document uses that term.</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Calibri"><br>
Or, if you wish, we can create a new term, Extended SCID (ESCID) and define
it to mean the concatenation of the Frequency Band with the MCID (or GSCID,
if you wish to persist that into the future). </font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Calibri"><br>
Or perhaps you want to change all of the other protocol docs to use the
term GSCID instead of MCID so that they are all consistent?</font><font size=3 face="Times New Roman">
<br>
</font><font size=2 face="Calibri"><br>
Which of these are acceptable, to you and the other CESG members?</font><font size=3 face="Times New Roman">

<br>
<br>
Dear Gippo,</font><font size=3 face="Times New Roman"> </font><font size=2 face="Calibri"><br>
<br>
I appreciate your attention to detail and looking at this early on, but
I have to differ re some conclusions. I note the following:</font><font size=3 face="Times New Roman">
</font><font size=3 face="Calibri"><br>
<br>
- </font><font size=2 face="Calibri">The
term GSCID was defined </font><font size=3 face="Calibri">as “</font><font size=3 face="Times New Roman">GSCID
= VN <b>. </b>SCID”</font><font size=2 face="Calibri"> where the “</font><font size=3 face="Times New Roman"><b>.</b></font><font size=2 face="Calibri">”
means concatenation.</font><font size=3 face="Times New Roman"> </font><font size=3 face="Calibri"><br>
- </font><font size=2 face="Calibri">The
terms SCID and GSCID are used more or less interchangeably in the CCSDS
320x0b document, but they mean different things. This is a flaw in
the current document that I have tried to remedy.</font><font size=3 face="Times New Roman">
</font><font size=3 face="Calibri"><br>
- </font><font size=2 face="Calibri">The
term SCID is defined specifically in the various protocol documents, 320x0
just references it.</font><font size=3 face="Times New Roman"> </font><font size=3 face="Calibri"><br>
- </font><font size=2 face="Calibri">The
term GSCID <b><i>does not</i></b> appear in any of our protocol documents,
TC, TM, or AOS. They tend to call the combination of the VN (actually
the TFVN) and the SCID an MCID, not a GSCID.</font><font size=3 face="Times New Roman">
</font><font size=3 face="Calibri"><br>
- </font><font size=2 face="Calibri">If
you search the CCSDS files you will find that the only reference to GSCID
is in this 320x0 document, and not in any others.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
All of that said, I think that there is really no impediment in the way
of extending the definition of GSCID to include the frequency band, because
globally, in fact, the frequency band has from the beginning been a part
of the actual physical and logical link layer signal. We just did
not acknowledge this until now.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>
But if you are worried about some confusion for others we could introduce
a new term for the FB </font><font size=3 face="Times New Roman"><b>. </b></font><font size=2 face="Calibri">VN
</font><font size=3 face="Times New Roman"><b>. </b></font><font size=2 face="Calibri">SCID
combination. I’m reluctant to call it a “Super” SCID, that sounds
like a kid’s toy. ;-} And in truth, I think that this is
more of a Global SCID than the current definition, and which the protocol
docs call an MCID. In effect we have given the same thing two different
names, surely that is not a good approach? Maybe we should align
this book with all of the existing protocol docs and call the VN </font><font size=3 face="Times New Roman"><b>.
</b></font><font size=2 face="Calibri">SCID combo an MCID and the FB </font><font size=3 face="Times New Roman"><b>.
</b></font><font size=2 face="Calibri">VN </font><font size=3 face="Times New Roman"><b>.
</b></font><font size=2 face="Calibri">SCID combo the GSCID?</font><font size=3 face="Times New Roman">
</font><font size=2 face="Calibri"><br>

Subject: </b>[CESG] Why renaming GSCID inf revised CCSDS SCID Code Assignment
Control Procedures?</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
<br>
Dear CESGers,</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
in order to gain time and not to delay eventual Poll and
start of Agency Review, I would like to anticipate that as SLS AD I wonder
about the need of renaming GSCID in revised CCSDS SCID Code Assignment
Control Procedures.</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
<br>
In fact the revised book includes a new definition of GSCID (see snapshot)
that is conflicting with the definition in the Blue Book in force (see
second snapshot) as the new one also refers to Frequency Band.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
<br>
First of all I think that it is not appropriate modifying a term used for
so many years (and for sure spread in "billions" of documents
from many agencies) also considering that the the prefix "Global"
is widely used for e.g. the Global VCID and Global MAP ID (for sure in
SLE and SLS books) without considering the Frequency Band.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
Therefore there would be a discrepancy of meaning about the term Global
between the GSCID and the GVCID</font><font size=3 face="Times New Roman">

Last, but not list the book title "CCSDS Global Spacecraft Identification
Field" points to a field i.e. a portion of data that is normally contained
in transfer frames. In other words while the actual GSCID matches completely
the contents of some bits of a Frame Header, the proposed future GSCID
will not.</font><font size=3 face="Times New Roman"> </font><font size=2 face="Arial"><br>
<br>
As a conclusion I would retain the current definition of GSCID while
adding a new definition for the concatenation of the frequency band
(FB), 2-bit Version Number (VN) and the SCID.</font><font size=3 face="Times New Roman">
</font><font size=2 face="Arial"><br>
This could be called Universal SCID, Super SCID, Supreme SCID, Frequenced
SCID or whatever you prefer. [Please consider some humour
in some proposed definitions.]</font><font size=3 face="Times New Roman">
