Bittransparent data is raw data coming from the isdn-network with
8khz rate. And believe me there is always data on the isdn-network ;-)
So in this mode of operation which is normally only used for voice,
fax and modem, you can't see if the data coming was sent from
the other side.
If you want to do data-tranmission, then you should use at least
HDLC-framing on layer 1. This makes sure, you only get data
if the other side sent you something.
