On the MTNL's website it is mentioned that the previous plan:
[B]Stands closed from 16.8.2007 for new registration and migration[/B]

So, I suppose that the plan is still open for existing members but no new registration or migration is possible. The speed is up to 2mbps so MTNL might not offer complete 2mbps. However, it's still a very good plan and quite beneficial for those who do lots of downloading at night.
