Review of Functional Resource Model</span>
<br>
<hr noshade>
<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=1><span style=" font-size:10pt;font-family:sans-serif">Only the
Master Channel and VC Mux functions of the TC, AOS, TM, and Unified SLPs
are covered by this initial FR set. FRs representing the upper functions
in these protocol stacks will be covered in a (near?) future set of FRs</span>
<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
Transmission, VLF USLP Reception, and FLF USLP Reception will be covered
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
are most associated with the products of their WGs, we welcome comment
on all contents of the candidate FR registry and the FR Reference Model
