Dear 10G-EPON TF members, Apology for late action, but here is
outline of issues to be solved for the Power Saving. I would like ask
Forks to make comment for this. 1. Reduction of numbers of Report
frame transmit An attached is two ideas which
describe how to realize the reduction of numbers of Report frame
transmission and summary of study items to be discussed in TF. As conclusion
of our study, in order to obtain merits of the Power Saving, current
CL93 have to be modified or specified with additional condition though it
looks like small modification. <Requirement for Common> -GRANT needs to be regularly
provided by GATE MPCPDU. -Maximize
report_periodic_timer from less than 50ms to 50ms. <Requirement for Proposal 1> - Usually, set GATE MPCPDU
which has Force Report flag =0. (It is allows that OLT sends GATE
MPCPDU which has Force Report flag=1.) - Specify that the ONU report
processing state diagram which allows transmission of A REPORT MPCPDU (Periodic
Transmission) with maximum interval if ONU requires no upstream traffic. < Requirement for Proposal 2> - Ignore for force report flag at
ONU. 2. Study of Suggested Remedy for
CL93 Still on going. It would be more
than welcome if someone can join in this task. 3. Other ideas for Power Saving Kuroda san proposed the reduction of
numbers of Report frame transmission, but if there may be other ideas,
please issue and discuss on reflector and upcoming Regards, kiyoshi Uematsu -----Original Message----- Dear Colleagues, March meeting minutes and
presentation materials have been posted on the web at

13-14: Comment resolution during
April Interim meeting In addition to commenting on draft
1.2, we identified the following big ticket items: 1) Damage threshold values ad hoc -
Frank Effenberger 2) Mathematical analysis of impact
of FEC codeword invalidation - Expected post-FEC BER

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 5) Jitter ad hoc - Ryan Hirth 6) FEC test vectors - Jeff Mandin 7) Power saving proposal - Kiyoshi
Uematsu The ad hoc leaders listed above will
make separate announcements on the reflector, outlining the issues to be solved
and plan of work. If you are interested in participation in one or more of
these discussions, please contact corresponding ad hoc leader listed above. Detailed information about April meeting
can be found here: http://www.ansl.ntt.co.jp/Interim_Meeting/index.html Please note that registration is
