Hi,I am from Kerala. I am planning to go for DataOne on my existing BSNL Land line connection. I am living in a area where frequent power failure occurs. Is the DSL modem supplied by BSNL requires external power supply? If yes then, is there any provision for battery backup for the modem so that I can use my Phone during power failure ? Otherwise I will have to go for a separate line for DataOne and it is very difficult to get a new connection right now in my area.Harish.
