Nearly, but not quite in that although the maximum speed might be the same,
the latency of a TA will be slightly higher. Still the latency of a TA is much
less than that of a modem with compression if the connection already exists
and zillions (well not quite) of times quicker when the phone call has to be
connected as well.

To my mind, the quick call setup is the most attractive feature of ISDN over
V90 modems. No doubt after getting connected I will soon be demanding that
Demon speed up their log in time as that will soon become the bottleneck.
