Hi Wim, In February I was inform by German officials the billing tone filters will be required. I was also informed there is a 1 year grace period after TBR 21 was approved. As a consequence it is not required to implement TBR 21 until 12/98. I was unable to determine if Germany will implement it sooner.

Does anyone know, if the billing >tone filters are still required for correct functioning of the modem when >CTR21 becomes in force ? > > >Regards Wim Maas.
