From what I have seen of the MTNL, the DSL modem is not tied to a specific tel. line. The PPPoE/PPPoA session login is based on userid/passwd, similar to a PSTN dial up scenario - it will work on any phone connection that is DSL enabled. When you used your home router @ work, your connection was logged against your "home" account programmed into your home router. Had you changed the password to some gibberish string, you would have got "authentication failed."
Does that mean if someone knows my password (and has DSL enabled on his line), he can misuse my account.
Absolutely, dial up accounts are vulnerable to this problem too. MTNL is setting the default password to the "CA" string for your tel. account (which shows up only your bill) but then it is _your_ responsibility to change it :)
What happens if router is attached to normal telephone line but account used is of DSL enabled line. Does it still work? May be MTNL might have activated DSL on all lines but not activated account for that NUMBER.
It is unlikely that MTNL has enabled all land lines to have ADSL.
OR other use can be is if my home usage is 350MB(400 scheme) I can use the remaining 50MB at office by changing username/password on router?
Yes in the current scheme of things.
I do not have MTNL DSL. Can someone who has it, check this? I am planning to get one. There can be uses and misuses of this bug/feature.
IMO, the security of your account is your responsibility. If you give out your password it is likely to be abused.
