Excellent presentation, thanks for the good work.
I probably will not be able to be on next week’s call so here are a few comments/questions. 1)
Slide 5/1st bullet states “Each parameter is announced once, following the Discovery GATE” whereas slide 9/1st bullet states “OLT announces … before issuing DISCOVERY GATE MPCPDU”.
Please clarify. 2)
Slide 7 – So my understanding is that if SP Index is set to 1 the message applies to the AGC, 2 indicates CDR and 3 is for Burst Delimiter. So if SP Count = 2 (ACG+CDR & BD) then you would see SP Index
of 1 and 3 only. Is this understanding correct? 3)
Slide 8 – So if SP Balanced = 1 and Repeat is odd the pattern becomes (SP + !SP + SP… + SP) and the pattern has a very minor imbalance. Is that correct? 4)
Slide 9/4th bullet – I see this answers my Q2. It seems odd to me that SP Index meaning should change for BD, you might want to consider always using SP Index = 3 for BD. 5)
Slide 10/3rd bullet – definition of “a full set” is weak (will any 2 or 3 messages be OK regardless of how far apart they occur in the transmission stream?). I would suggest adding a requirement
that the SP messages be transmitted in order and in immediate succession. That way the ONU can avoid accidentally picking up SP1 from one message and SP2 or SP3 from a different definition set. This should be added to Slides 9 & 10. Another option would
be to add an SP_ID of 2-3 bits to the SP Info field to clearly id a full message set. Best Regards Duane From: Marek Hajduczenia [mailto:mxhajduczenia@xxxxxxxxx]
Dear colleagues, Attached please find the first pass at the at the Upstream Burst Delimiter and Sync Pattern Assignment proposal for the next TF meeting, including the format of the new SYNC_PATTERN MPCPDU, individual fields within the said message, as
well as a number of ONU and OLT behavior details expected. Please note that this is work in progress and comments / feedback are more than welcome. I would like to request a time slot during the next conference call we have scheduled so that I can go over
the deck as is, and address any questions and comments. When reviewing the deck, you will notice that the default values for SP1, SP2, and SP3 are currently marked as TBD on slide 3 and need a specific proposal. The remainder of the contribution does not change, irrespective of the actual values
assigned to SP1/2/3 elements. Regards Marek To unsubscribe from the STDS-802-3-NGEPON list, click the following link:
