Recently i bought the same ONT for BSNL FTTH. But they are not able to help to configure it. Since you are famililar with it, could you guide me through this ONT configuration. It would have been a huge help for me.Good news. I am now able to login with telecomadmin/admintelecom !!!
Submitted following two commands as suggested by the vendor in given sequence
reset (not sure this was required)
After the login I was able to setup the BSNL internet.
Thanks for the support Mayank!
