I am using broadband connection from BSNL with ADSL modem. I don't have dial up modem and hence i am using my moodem thru USB port. Is it possible to use it for dial-up connection? Please help.

Dont have a clue as to what you mean by dial-up. Cos ADSL is a broadband thru phone lines. So why would you want to use the modem for dial-up purposes ? Sorry mate you've completely lost me. Could you provide more information as to what your trying to do, perhaps we can help better then.

forget it.....
the modems do not have any capability to Dial any thing... as they are just recognised as a LAN device on your computer.... so ur computer does not know it is a modem!

alright since everyone has just said no ( including me ) lemme clarify this to u
as stated above by mario the pc detects it as a lan device
hence it has no drect access to your telephone line
APART from this if u realise isp's ( atleast some ) install a sort of splitter with ur modem
one line in
one phone out
one modem out

this is not simply so u have a parallel line
this splitter also has a filter in it which segregates the data channel and voice channel from ur telephone line
since adsl modems tend to make a high pitch noise this is a good idea obviously.

atleast thats what it says in the theory of dsl :p
so i guess these 2 points should be enough for everyone to understand as to "WHY AN ADSL MODEM CANNOT BE USED TO ACCESS PHONE LINES ( to make calls, dial up, fax etc. )" and as to "WHY A DIALUP MODEM CANNOT BE USED AS AN ADSL MODEM "
