- That's the same story I got from them, and it's pretty amazing since the whole
- concept of ISDN was to take advanage of existing T1 links between CO's. And
- it doesn't take a whole T1 in any event. Any time slot of an inter-CO T1
- should be capable of being statically or dynamically assigned to an ISDN B
- channel, and the signalling can be done on a variety of links including T1
- time slots. (Of course, with older T1 hardware you would only get 56k per
- timeslot, but ISDN allows for that.) Basically they just were using this as
- a means for extracting more $$$ from companies doing ISDN R&D.

- I doubt that they've actually installed more T1 lines just for ISDN; they've
- just decided to make them available "free", rather than billing you an extra
- few thousand dollars a month.
-
- ISDN is now supposed to be usable between all ISDN-capable switches in the
- SF bay area. I haven't been able to get a straight story on ISDN data calls
- between here and other metropolitan areas. I wonder if the long distance
- carriers are going to try to gouge for data calls?
