The former may be true, but it doesn't follow from the latter.  A modem
typically interrupts somewhere between every character and every 10-15
characters.  A decent network interface interrupts once per packet (or
even less than that, if packets are coming in fast enough and the card
and driver support multiple receive buffers).

Thus, I'd say, it depends on what the T1 interface hardware is like.
If it's decent, I'd be astonished to find a 386 "WAAAAAAAAAAAY to
slow".  (Not that I haven't been astonished before, nor won't be again,
of course.)
