<span style=" font-size:10pt;font-family:sans-serif">Dear Tom,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">after some iterations
within the RFM WG on the exact terminology to be used instead of bit, I
am pleased to be able and send you the WG approved editorial changes to
the TC recommendations.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I trust you can
include these in the upcoming B29 publication along with the approved revisions
of REC 2.4.17A, 2.4.18, 2.4.22A, etc. as per AD resolution.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">At the next meeting,
the WG plans to do the same exercise with the TM recommendations that will
also require a change in the glossary.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Best Regards,
Enrico</span>

<br><span style=" font-size:10pt;font-family:sans-serif">Dear All,</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">as you know all
our missions have used or are currently using the standard telecommand
BCH (63,56) encoding. For all these cases, the bandwidth expansion is 1.125
which basically means bit rate equals symbol rate. For this and other historical
reasons, all 401 recommendations for telecommand only talk about bit rates
assuming that they are actually symbol rates.</span>
<br><span style=" font-size:10pt;font-family:sans-serif">With the first
missions considering LDPC 1/2 for telecommand, there is a need to remove
the confusion by changing bit rates into symbol rates while keeping the
same limits as in present recommendations. I think this is just a purely
editorial issue.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Please let me
know if you agree with my proposal and if anything is missing in the attachments.
If I do not hear from you by December 12, I assume your concurrence and
will submit the attached document (or its amended version in case of suggestions)
to the CCSDS editor.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Best Regards,
Enrico</span>
