It has nothing to do with Europe/US differences. Read the (european) ISDN
standards to get an impression what is possible on the D- and/or B-channels,
there is much more possible than telephony and/or IP/PPP. Fax and Video are
just two examples. As i said, a TA allows you to do just those (ISDN-) things
which are supported by the TA's firmware.
