DOCUMENT NUMBER:   CCSDS 131.3-P-1.1        Pink Sheets, Issue 1.1
DOCUMENT NAME:     CCSDS Space Link Protocols over ETSI DVB-S2
DATE ISSUED:       April 2021
PAGE NUMBER:       2-1            PARAGRAPH NUMBER:  Figure 2-1
RID SHORT TITLE:   Scope of the Recommended Standard does not cover all of Physical Layer
------------------------------------------------------------------
DESCRIPTION OF REQUESTED CHANGE:  (Use From: +ACI-...+ACI- To +ACI-...+ACI- format)

Change Figure 2-1 so that the scope of the thick-bordered box (RECOMMENDED STANDARD CONTENT) extends only partially into the area corresponding to the CCSDS Physical Layer but not to the bottom of the Physical Layer, and insert a regular-thickness-lined box labelled +IBw-Radio Frequency and Modulation Systems+IB0- beneath it.

------------------------------------------------------------------
CATEGORY OF REQUESTED CHANGE:
     Technical Fact +AF8AXwBf-    Recommended +AF8-X+AF8AXw-    Editorial +AF8AXwBf-
NOTES:
TECHNICAL FACT:  Major technical change of sufficient magnitude as to
 render the Recommendation inaccurate and unacceptable if not
 corrected.  (Supporting analysis/rationale is essential.)
RECOMMENDED:  Change of a nature that would, if incorporated, produce
 a marked improvement in document quality and acceptance.
EDITORIAL:  Typographical or other factual error needing correction.
 (This type of change will be made without feedback to submitter.)
------------------------------------------------------------------
SUPPORTING ANALYSIS:
As currently presented, figure 2-1 implies that the Recommend Standard specifies all aspects of both the Sync and Channel Coding Sublayer and the Physical Layer +IBM- e.g., frequencies, polarization, EIRP levels. etc. Correcting the figure to show the existence of an underlying +IBw-Radio Frequency and Modulation Systems+IB0- sublayer (the term used in figure 2-1 of CCSDS 131.0) informs the reader that the content of this Recommended Standard does not indeed cover all aspects of the RF Physical Layer, and must be sought elsewhere in order to create a full +IBw-stack+IB0-. 

NOTE +IBM- this recommended change also applies to CCSDS 131.2 (+IBw-Flexible Advanced Coding and Modulation for High Rate Telemetry Applications+IB0-) and CCSDS 431.1 (+IBw-Variable Coded Modulation Protocol+IB0-)
