since both the connections are in ur name i dont think that even if they detect it they'll do much..but using one account on another line is not something that MTNL permits which is why they have implemented the port binding thingy..However, i do know that they regularly check user accounts to find out if anybody is using 2 mbps on a 256k/512 kbps unltd account and reduce their speed accordingly..this checking period can range from a week to abt a month or even more. In short even if u access 2mbps speed on a 2 mbps line by using a 256 K unltd account.. they will detect it, reduce its sync rate to 256 K and port bind it to the account which is being used on the line. So u will be stuck with 2 lines at a sync rate of 256 K , one limited another unlimited, port binded to each-others account.When this will happen no one can tell..but it will happen..sooner or later... i know that from experience...so its ur call..if u want to go thru the headache just for 1-2 months of unltd downloading @ 2mbps..
