Thanks for the answers folks. I think I now understand that indeed, the "Digital Trunk" is really nothing more than the same analog services, just delivered digitally. no outbound ANI (of especial interest), etc....<BR>
<BR>
This is in the Dayton Ohio area, major telco vendor. I'll have to pursue the differences with them further, as the pricing is about double for the PRI vs the "Digital Trunk". I'd like to move 7 analog lines to a digital interface, but just can't cost-justify it in this scenario :-(<BR>
