RF/LF




Rich,
Unfortunately I missed the discussions about RF/LF (Had to be in the XAUI
sessions). From the least I sow at the end, I thought that only the Tx
machine in the PCS-PMA of the DTE-XGXS considering any of the faults (In
order to come to a state where you transmit POS after /A/). Is this correct?

And:
In the Rx direction you do not have to alternate the XGMII anymore-rather
you send the POS code whenever it comes, because the RS resets its machine
only after 128 non fault indicated bytes, and the max distance between POS
is 32 (Max A distance).

Is this correct?

Thx. for your help,
Boaz
