That sounds really cool! :D
SGI Indy's interestingly have ISDN modems built in. I always thought
that might be a fun thing to tinker with.

sorry if this topic feels offtopic for the c*net list, everyone.? :)
true fact: i started looking into x.25 because i was curious about
temporary signalling connections and how they work on the Definity.?
i
wondered whether it would be possible to bolt on a data network next
to the existing c*net voice network to facilitate transparent isdn
interworking.? sort of like how the PSTN was slowly transitioned from
vf-only to a dual vf/packet network with ss6 and later ss7.
my thinking went: if things can be made to work that way, two
c*net-connected pbxes, each with local pri's homing on router that
splits/recombines all the datastreams properly, might could think
they're speaking end-to-end isdn, not even noticing anything unusual!
that would be neat.
so i started gathering equipment and learning how it all fits
together.? got a bit sidetracked though, haven't yet gotten around to
answering that first question one way or the other.
it does seem that you can statically configure a set of Definity
pbx's
into a larger network in a non-isdn environment, using regular vf
telephone trunks and sending the signalling traffic over X.25.
haven't gotten that to work properly yet either but i'm pretty close.
