How many ways to add the newly online onts in the OLT
There are two ways to add the newly online ONTs: auto-find and add manually. The activated process is nearly:
1. ONT receives US_OVERHEAD message from OLT and adjust its parameters;
2. OLT gets the SN of the newly ONT(by Broadcasting and Randam delay );
3. OLT assignes ONU-ID to ONT;
4. OLT measures the arrived phase from the upstream of ONT(mearure RTD);
5. ONT account the sending windows by the value of EqD and BW Map;
The process implentes communication exchange by the flag field and PLOAM message in the up and down stream.
