[8023-10GEPON] FEC vectors adhoc



Per Glen's request, here is an outline for the work on FEC test
vectors...

1. The following people have indicated interest in the FEC vectors work:

  Fumio Daido	-   Sumitomo
  Frank Effenberger -   Huawei
  Dongning Feng	 -   Huawei
  Ryan Hirth -   Teknovus
  Seiji Kozaki -   Mitsubishi Electric

Additional participation is welcome.

2.  Work items

The discussions in Orlando did a lot to clarify the bit order and text
interpretation issues.

I am currently preparing revised vectors that incorporate the TF's
Orlando decisions on bit order and some additional text to disambiguate
the notation and processing for each step as much as possible.

There are basically two work items:

	a) Arrive at an agreed-upon set of parity blocks for a
particular set of input blocks
		- this may involve some additional discussion to clarify
bit order etc.

	b) Resolve any issues of vector presentation:

		- ie. mainly the issue of notation for presentation of
input and output 66b blocks, but there may be other issues

3.  Schedule

March 30 - Distribution of revised vector text (Jeff)

March 30 - April 3  
	
	* Email discussion of algorithm issues 
		- these should be minimal, since we did a good job of it
in Orlando and afterward
	
	Confirmation of parity results (hopefully) 
	
	Updates to text (hopefully early in the week rather than later)
		- issues of presentation can be dealt with between the
submission deadline and the Tokyo meeting

April 4 - Submission of vector text for Tokyo

Dear ah hoc leaders:

I am requesting you to make announcements of your planned activities on
the reflector, outlining the issues to be solved and plan of work.

2) Mathematical analysis of impact of FEC codeword invalidation
   - Expected post-FEC BER - Seiji Kozaki
   - Probability of receiving a corrupted frame - Raymond Leung
(tentative)
3) Analysis of Tx and Rx PCS delay - Eric Lynskey
   - Impact of IDLE insertion
4) Clause 64 ad hoc - Marek Hajduczenia
