The point is not that the OLT has to use both bytes, the point is it legally can and the ONU is duty bound to accommodate that. Without some upper bound that can come to over 2 seconds of delay. Clearly this is excessive.

Duane,
What would be then "reasonable"? It is not like OLT has to use all 2 octets provided for specific values.

I previously commented on the 2 byte repeat parameter in the SP messages and, at the time, it was suggested that this really didn’t matter. However, I have to disagree with that opinion.
In 10G-EPON we incorporated the Data Detector mechanism to determine when the beginning of the burst should occur. The mechanism depended on a delay line that essentially matched the duration of burst preamble, burst delimiter and laser on time (i.e., sync time). In 10G-EPON this was a fixed duration. We have now made that duration variable and of arbitrary size through the setting of SP1, SP2 and SP3 and any repeats.
What will the ONU be expected to accommodate with respect to maximum delay needed?
Without placing a bound on this total time I don’t see how we can claim technical feasibility. If some OLT vendor decides a very long sync time is OK per the standard and an ONU cannot accommodate that long time interoperability is not achieved, neither device is non-compliant and we have not achieved our goals.
I suggest we place a reasonable limit on the total sync time in the standard and size the repeat parameters accordingly.
Best Regards
Duane
