In all the discussion on ISDN in Solaris 2.x and Sparc 10 machines
there's been no mention of the ISDNKit in NeXTSTEP 3.0 due August
'92 (now in 2nd beta release).  By using an ISDN eXTender box, available
from Hayes, you can use the NeXT DSP external port as a high speed
ISDN connection.  For details see "ISDN Comes of Age" by Simson L.
Garfinkel in the Summer '92 issue of NeXTWORLD.  However, to get a feel
for what is will be like I'm including an old posting to comp.sys.next.misc
that I thought was pretty cool.  I figure that if that Sparc 10 got into
the FAQ, the NeXT should be there too...  Their support appears to be 
very favorable for ISDN in the future.  I would have included more
except the original post was a NewsGrazer posting and unreadable
by most.  I can only assume that he included screen dumps as he
went along...

Our ISDN software is set up for telecommuting.  You need to have a machine
at home and a machine at work (not necessarily on your desk).  Each of these
machines need to be connected to an ISDN line with the Hayes ISDN Extenders.
Given some configuration at the work end (fairly straightforward) and very
minimal configuration at the home end, you will be set up with a dialin 
connection.

When your machine at home is setup with ISDN, the Loginwindow panel will have
a small icon of a phone in the lower right-hand .  When you click on that
icon, the connect panel comes up.  

Enter in the phone number of your ISDN line at work and hit connect.  After a 
few seconds, the connection will be made and our ISDN software will start to make
your machine at home look like a virtual clone of your machine at work.  (Same
filesystems, same netinfo parent, etc).  After all of that is finished (a minute 
or so), the Loginwindow will reappear.

You are now live on the network.  If your machine at work is on the Internet, then 
your machine at home is as well. Login with your regular login and have fun.
