Dear CESG Members,

Conditions for approval to release CCSDS 901.3-R-1, Functional 
Resource Model (Red Book, Issue 1) for CCSDS Agency review have 
either been explicitly disposed to the satisfaction of the AD(s) who 
voted to approve with conditions or have been deemed disposed due to 
lack of response within the period of time allowed in CCSDS 
A02.1-Y-4, Organization and Processes for the Consultative Committee 
for Space Data Systems. The Secretariat will now proceed with CMC 
polling to authorize publication.

Approval to release CCSDS 901.3-R-1, Functional  
Resource Model (Red Book, Issue 1) for CCSDS Agency review 
Results of CESG poll beginning 28 April 2022 and ending 12 May 2022: 
                Abstain:  0 (0%) 
Approve Unconditionally:  2 (50%) (Barkley, Wilmot) 
Approve with Conditions:  2 (50%) (Merri, Aguilar Sanchez) 
Disapprove with Comment:  0 (0%) 
    Mario Merri (Approve with Conditions): 
1) Section 1.3 "Scope" states that the scope is  
limited to IOAG service cat 1 and 2. 
"FRs are abstract representations of the  
functionality needed to provide space  
communication and tracking services, defined at a  
level of granularity sufficient to specify the  
configuration parameters, monitored parameters,  
and notifiable events associated with that functionality. 
FRs exist to represent such information as it  
applies to a cross support interface. If a  
processing function does not have unique  
monitored parameters, notifiable events, or any  
configuration parameters that need to be set  
(possibly through configuration profiles),  
queried, or reconfigured (via real-time control  
directives), then it does not have an FR to  
represent it. It should be noted that only one of  
these facets needs to be present in order for a  
function to need to be represented by an FR." 
It should be clarified in the text that the FRs  
shall be limited to hw/sw that is immediately and  
directly related to communication and shall not  
be used for abstract representation of other  
devices onboard or on the ground, e.g. a Camera  
or a Gyro.... for such devices MO services should  
be the prime choice for abstract representation  
of the interface. This is consistent with the so called "London agreement". 
2) It should be also clarified in the text  
(Section 1.3 Scope?) that, when it goes on-board  
even for the RF elements, the aspects of TM/TC  
and operations in general should be handled  
through MO M&C services rather than using FRM for  
monitored parameters, notifiable events, or any  
configuration of those devices. This is  
    Ignacio Aguilar Sanchez (Approve with Conditions): 
Positively impressed with the organisation, depth  
and detail of this draft standard. Will review it  
carefully during Agency Review. Nevertheless, a  
couple of minor editorials (will not use the PID form): 
-Ref [6]:  There is a very recent issue 4  (April 2022); 
- Page 2-5, paragraph b): the terms 'channel bits' shall be replaced by 
'symbols'; on the next sentence the term 'bits' shall be replaced by 
- Page 2-5, paragraph c): the term 'bits' shall be replaced by 'symbols'. 
    Jonathan Wilmot (Approve  
Unconditionally):  Document is really for agency  
review. May submit comments during agency review process.
