BTW, I forgot to mention the built in ISDN ports in some of my Sun kit - SS10 and SS20, I
think.

  Somewhere in storage I have an old Adtran box that
takes a T1 (pri) line
 in and breaks out a bunch of POTs ports and 2 ISDN BRI lines that will
 source other equiptment.

 I know the MAX 4004 boxes will source a PRI out on the second channel if
 you want to to put one inline with a PBX and skim some channels off the
 top for data or dialup. At one point in time I had a ISDN PRI split out
 to 7 pots lines, 8 private dialup lines, and a 512k data channel with a 
 class c address block (256 IP addresses) assigned before I gave up the
 office about 5 years back.   
If I understand correctly, the equipment mentioned above will still require some sort of
dedicated hookup to a telco provider in order to transport packets between two local
devices. We don't have that and we don't need/want to get it (we have POTS service
and DSL over POTS).

I was/am just looking for a simple solution for interconnecting my packratted ISDN devices
for some testing and fooling around, like room-to-room intercom, using ISDN between
computers (like a slow-speed LAN) or playing back audio from a computer through an ISDN
phone.

Thanks for your suggestions anyway...
