Dear All,<br>
<br>
I have responded to the edits and comments of both Marjorie and Ignazio
based<br>
upon their latest edits to the TC Space Data Link Protocol with SDLS.<br>
<br>
Please see the following URL that contains proposed changes to both TC
and<br>
AOS. (TM will follow essentially the same types of changes as AOS, so after<br>
we have consensus, I will modify TM.)<br>
<br>

Your Figure 6-c Marjorie in the TC book is quite innovative. You have also<br>
clearly identified all the processes and functions involved in the TC SDLS<br>
case. Under the Notes in Section 6.3.7, I had to change the reference to<br>
6.3.2 since the order of processing for SDLS does not follow Section 4.3.5<br>
(which was correctly called out in the text of 6.3.2).<br>
<br>
I decided not to include any figure such as 6c in the AOS book, simply<br>
because the COP-1 is not an issue for AOS and we are only dealing with
the<br>
order of processing of the AOS functions and SDLS, which I believe is handled<br>
easily with text. I added a section "Error Reporting" to discuss
the<br>
verification issues in lieu of the order of processing discussion in TC.<br>
<br>
For both documents in Section 6.4.2, I softened the text to say that the<br>
Virtual Channel Reception Fct will not deliver (in lieu of discard ) the<br>
frame if SDLS reports an error. In my mind, I want to prohibit the function<br>
from delivering the frame to the user, but not prohibit the capability
for<br>
future forensic analysis by a select group of analysts. I think this best<br>
adresses Ignazio's concerns and questions. (Change also added to AOS).<br>
<br>
Please let me know if the text for both TC and AOS is now consistent and<br>
acceptable. If so, I will procede to make the changes to TM as well.<br>
<br>
Best regards,<br>
<br>
