RE: Link Status thoughts


In X-PCS/XGXS, I have seen the following fault indicator candidates:
(please correnct me If I am listing wrong names)

(1) send N fault indicators and N /A/K/R/ Idles alternately (Shimon, Rich)
(2) replace /A/ with the fault indicator (Pat)
(3) put the fault indicator in after each /A/ (Pat, Shimon)
(4) send a fault indicator once every N /A/K/R/ Idles (Rich, Osamu)

You can find Rich's 10GFC proposal in

Best Regards,
