also your internet connection needs to be activated from local exchange first to even establish ADSL link so go to your local exchange & ask them if your line has been connected to internet network for ADSL link & then get username/password.
as long as snr is above 15 & attn below 50 you will not face problem.DSL does not blink after link is established & internet light blinks every time there is data transfer.
^^sometimes it happens & in few lucky cases speed increase remains for 1-2 days.
@Ashok Verma,your values are fine & looks like you are not far from local exchange(<3km).
They said "As you have new landline(22 july ) and broadband connection(23 july ),so the user name and password will be available tomorrow"
Hopefully I will get them tomorrow
