Here is the price list presented at:
http://ste.xservices.com/briefings/ste_briefings.html
"L-3 STE Release 1 Products and FORTEZZZA Plus Crypto Cards are
available to order today!
STE Office (ISDN/PSTN) $3250.00
STE Office (ISDN Only) $2450.00
STE Tactical $3725.00
STE C2 Tactical $4422.00
STE Ship/Shore GW/IWF $3878.00
STE Data (ISDN/PSTN) $2930.00*
STE Data (ISDN Only) $2320.00*
FORTEZZA Plus KOV-14 Card $ 255.00"
The material at this site makes it pretty clear that ISDN bandwidth is
required for native STE operation. Some models can operate on regular phone
lines (PSTN) with clear and STU-III modes for now, with future upgrades to
support new narrow band systems being developed.

Indeed. The STE sets and Fortezza cards can each be programmed to enforce a
variety of usage controls. Given the versatility of STE, I am suprised that
e-mail isn't built in.
