Most TAs have a built-in DSU (AKA NT-1 device), but if you get one without
it, you will either need to provide your own or rent one from NTT.
If you want to have NTT provide the DSU, be sure to tell them when
you order the service.  The installers usually don't have spare
DSUs on the truck.

The data network may be high-speed, but the Flet's connection itself
is not.  Flet's works like OCN; the 64 kbps of Flet's is not a CIR, it is
the highest speed you can in theory achieve.  However, like OCN, you can
(and usually will) see much lower speeds.  Flet's gets you a flat-rate,
always-on connection at a low price, but you give up performance in
exchange.  Our experience has shown Flet's to be quite a bit slower
than dial-up INS-64.  

If you feel the need for speed (at all), you probably won't like
Flet's-i.
