FAQ-How to check if ONT sends register message to GPON board

Publication Date:  2012-07-25 Views:  62 Downloads:  0
Issue Description
Q:

Sometimes we ever meet some issue that ONT cannot become normal on OLT, we want to know why, the configuration is not corect or ONT is really down or some other reasons? If we can know that ONT has mutual messages with OLT, we can focus on the configuration info. If there's no message from ONT at all, we need send FSE to site to check the optical power and power supply.
