<span style=" font-size:10pt;font-family:sans-serif">Reminder - I have
not received any inputs to date. If you are busy and think you have no
time this week, I can propose an extension of the deadline by some 2/4
weeks given we have not seen this big document before, etc. I could even
propose that Holger did a webex presentation for us before we look at it.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">I must confess
that I tried to read it at least 3 times but got something with higher
priority and stopped all 3 times. Therefore, basically I have to start
from scratch.</span>

Review of Functional Resource Model</span>

<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Dear CCSDS Colleague,</span>
<br><span style=" font-size:10pt;font-family:sans-serif">This is a kind
request to participate with your Working Group(s) in the review of the
Functional Resource Model created by the CSS/CSTS WG. The review is based
on a word document hosted on CWE, review instructions and further explanations
can be found inside the document:</span>
<br><a href="https://cwe.ccsds.org/css/docs/CSS-CSTS/SANA/functional_resources_css_tier_1.docx?Web=1"><span style=" font-size:10pt;color:blue;font-family:sans-serif">https://cwe.ccsds.org/css/docs/CSS-CSTS/SANA/functional_resources_css_tier_1.docx?Web=1</span></a>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Optionally also
the Functional Resource Reference Model Magenta Book, accompanying the
Functional Resource review can be reviewed by including comments and changes
in a copy:</span>
<br><a href="https://cwe.ccsds.org/css/docs/CSS-CSTS/SANA/FunctionalResourcesRefModel_MagentaBook-W-04-200717.docx?Web=1"><span style=" font-size:10pt;color:blue;font-family:sans-serif">https://cwe.ccsds.org/css/docs/CSS-CSTS/SANA/FunctionalResourcesRefModel_MagentaBook-W-04-200717.docx?Web=1</span></a>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">The end of the
review is 19th October 2020.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif">Your review of
the Functional Resources will help ensure that inter-agency cross support
is properly stated in technical terms and will be much appreciated.</span>
<br>
<br><span style=" font-size:10pt;font-family:sans-serif"><b>Background</b></span>
<br><span style=" font-size:10pt;font-family:sans-serif">The Functional
Resource Model (FRM) defines, in abstract terms, the functions that a ground
station performs to provide Tracking, Telemetry and Command (TT&C)
services to a spacecraft. The goal is to arrive at a standard representation
of TT&C services, thereby facilitating standards for inter-agency cross
support. The functions are organized around logical strata including Aperture,
Physical Channel, Synchronization and Channel Coding, SLS Radiometric Data
Production, Data Transfer Services, SLS Data Delivery and Production and
others. The functions are defined via configuration parameters, monitored
parameters, notifiable events, and associated control directives.

<li value=2><span style=" font-size:10pt;font-family:sans-serif">For USLP,
only the Fixed Length Frame (FLF) USLP Transmission FRs are covered in
this initial set. FRs representing the Variable Length Frame (VLF) USLP

in a (near?) future set of FRs</span>
<li value=3><span style=" font-size:10pt;font-family:sans-serif">While
we are asking specific WGs to primarily review the FR Sets and FRs that
