Very peculiar problem I am facing these days in my broadband connection.That when the connection was provided to me,it worked satisfactorily for a month.Later I did not get link even after several complaints lodged to BSNL authorities.Now what I observethese days that when there is no dial tone in my line,I get link and can connect to internet.But as soon as dial tone is restored the link lamp starts blinking.What could be the possible fault in my line.
