Dear Walter and Christian,
I think you are mixing up the F12 blocking rule and the rule of removing the paper. Please note the difference between these two:
Removing the paper
Migrate carriers can stop sending paper invoices as early as 3 months after they have migrated. Please also note that the ACH has also decided to remove the paper immediately after migration. Please also see the FAQ section on the SIS website where this topic was covered.
Blocking ICH F12 claims
Migrated carriers may also call the option of blocking ICH F12 claims from non-migrated carriers. This can be in effect after a 6-month hold plus a 6-month notice. So the earliest time at which this option can be in effect is Sept 2012.
Please refer to the post Grace period for inward and outward billings in the Rules, Policies, and Codes discussion board, where both of these topics were discussed.
Hope that clarifies.

we have received from different source following statement:
From a SIS perspective after XX will have sent the notification (initial 6 months black out from September till March 2012), there will be another 6 months after which you will not accept incoming paper invoices, so earliest September 2012.
During first year of SIS live you must accept current incoming billing, in Sept 2012 the earliest you can refuse the paper medium, as long as you send the notification six months in advance.
could you please be so kind and verify this procedure if in line with your regulations.
