implementing your RID to move the definitions of terms from annex C to

<b>Physical Layer: </b>The layer below the Synchronization

to create and operate the channel. At the receiving end it provides
the reception, demodulation, and symbol synchronization for the channel.</span></p>

The terms above are listed in 1.6.1.1 as terms from OSI Basic Reference
Model, the annex-C definitions do not precisely match those of OSI Basic
Reference Model terms, and it makes no sense to claim use of the OSI terms

colleagues,</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
I did not received additional comments on the RID dispositions.</span><span style=" font-size:12pt;font-family:Times New Roman">
<br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
Hence, I believe the agency review of CCSDS 231.0 can be considered closed
with final dispositions as by attachment.</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
Additionally, there is the editorial noticed by John Pietras (but not reported
as a RID)</span><span style=" font-size:12pt;font-family:Times New Roman">
<br>
<i><br>
In Section 2.2.3, the last sentence of the first paragraph currently says,
“This is described in section 4.” It should say, “This is described
in section 5”.</i> <br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
I kindly ask the AD to issue a resolution.</span><span style=" font-size:12pt;font-family:Times New Roman">
<br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
Please notice that given the nature of the update, and considering what
reported in the Charter, a prototype is not required.</span><span style=" font-size:12pt;font-family:Times New Roman">
<br>
<br>
</span><span style=" font-size:10pt;font-family:Arial"><br>
@Tom, given the simple changes, can you implement directly the dispositions

Andrea, <br>
<br>
Sure enough, your email messages about RIDs to the “TC Coding” Blue Book
did not reach me, or presumably the rest of the working group. There
were two more RIDs submitted by NASA (one by David Ni, one by John Pietras),
but both are duplicates of the JAXA RID, which noted the error between
“Sending” and “Receiving” in the captions of Figures 2-4 and 2-5. <br>
<br>
John Pietras also noted that there’s an incorrect cross-reference in the
document, though it's outside of the material covered by the RIDs. In
Section 2.2.3, the last sentence of the first paragraph currently says,
“This is described in section 4.” It should say, “This is described
in section 5”. <br>
<br>
I hadn’t seen your two RIDs before, but both look like good ideas to me.
By preference, I’d change the wording of each of them slightly as
follows, but I don’t feel strongly about it. <br>
<br>
RID AM-01 <br>
I would change the “To:” text to be: </span><span style=" font-size:12pt;font-family:Courier New"><br>
When BCH coding is used, the Pseudo-Randomizer defined in this section
is required unless the system designer verifies proper operation of the
system if this Randomizer is not used. Its use is fixed for a Physical
Channel and is managed (i.e., its presence or absence is not signaled but
is known a priori by the receiver), per Table 8-2.</span><span style=" font-size:12pt;font-family:Times New Roman">
<br>
RID AM-02: <br>
I would change the “To:” text to be: </span><span style=" font-size:12pt;font-family:Courier New"><br>
6.3.1 <strike>The randomization shall be applied at the transmitting end,
and it</strike>When BCH coding is used with the Pseudo-Randomizer, randomization
shall be applied only…</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:12pt;font-family:Courier New"><br>
…</span><span style=" font-size:12pt;font-family:Times New Roman"> </span><span style=" font-size:12pt;font-family:Courier New"><br>
NOTES <br>
1</span><span style=" font-size:7pt;font-family:Times New Roman">
</span><span style=" font-size:12pt;font-family:Courier New">Requirements
for randomization of fill data are specified in 3.4.3 for BCH coding <strike>and
4.4.3 for LDPC coding</strike>.</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:12pt;font-family:Courier New"><br>
2</span><span style=" font-size:7pt;font-family:Times New Roman">
</span><span style=" font-size:12pt;font-family:Courier New">Randomization
for BCH coding is optional, and managed per Table 8-2.</span><span style=" font-size:12pt;font-family:Times New Roman">

Dear all,</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
with reference to the Agency Review of CCSDS 231.0 "TC Synchronization
and Channel Coding", we received the RIDs in attachment (1 SLS, 2
ESA, 1 JAXA).</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
<br>
From a quick review they all appear minor modifications. Hence I would
propose to draft dispositions by correspondence instead of having a dedicated
telco.</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
<br>
Please let me know if you have any issue with the proposed approach <u>no
later than 9th April EOB (PST)</u>.</span><span style=" font-size:12pt;font-family:Times New Roman">
</span><span style=" font-size:10pt;font-family:Arial"><br>
<br>
If I will receive no objections, I will then provide a first draft of dispositions
for the WG assessment.</span><span style=" font-size:12pt;font-family:Times New Roman">
