Dear Greg,
        please be informed that the WG, discussing RID ESA-GPC-27, decided 
to remove the longest block size to be studied.

Best regards

Dear Greg,
        there are some "historical" reasons for that TBD that would take 
long to write.

On the same topic I have subimmeted  a RID ESA-GPC-27 (see below for the 
CWE location)

Therefore the matyter is under WG discussion and I take the occasion to 
silicite WG Memebrs to provide their position with respect to the above 
mentione  RID ESA-GPC-27.

[Sls-cc] Maximum Frame size for Turbocodes?






Dear CCSDS Coding & Sync WG,
 
I just want to confirm that the maximum allowable transfer frame size is 
1115 octets when one uses a Turbo code. 
 
A NASA mission in pre-phase A has approached me to ask if CCSDS has 
completed any further studies per the comment in the current standard 
below to  allow missions to use the 2048 octet frame size.  Have any 
further studies  been carried out or are planned by CCSDS ?
 
Currently Section 8 of the TM Sync and Channel Coding  (CCSDS 131.0-B-1 ) 
states:
 
 
8.6.2 Performance for only the following information block lengths (i.e., 
Transfer Frame lengths) has been validated by CCSDS and approved for use 
(values are in octets): 
a) 223; 
b) 446; 
c) 892; 
d) 1115; 
e) 2048. 
NOTE – Interleaver parameters for the length 2048 octets are under study 
by the CCSDS. Until finalized, use of this option is not recommended.
 
 
Looking over the pink sheets (ccsds 131.0-P-1.1) I did not see any new 
information on this section.
 
Thanks and best regards,
