I'm working with two BinTec ISDN-Boards for half a year or so. They work
very fine. Using ftp you can reach 7.5 KByte/second on a line between
a Sparc 1+ and a Sparc 2. There is a nice access control mechanism included 
in the software: You can explicitily allow or deny addresses/ports/protocols 
to be accessed from the ISDN line. I don't know the price. You should contact
support@bintec.de (Mr. Schmidt) for more information.

I bought the book and it answered all my questions. (Well most of them).
It's written as an introduction to ISDN and it covers everthing you need
to know.  It covers the concepts, protocols, and acronyms, and a lot more.
It also covers the history, and outlines how the different standards
commities work.  It has a whole chapter that outlines what each of the
local US phone companies are doing or have been doing with ISDN.

If you want to get up to speed on ISDN, you should read this book.

NeXT ships ISDN with every 3.0 system.  You do need an ISDN interface  
(about $350) called the Hayes eXTender that plugs into the DSP port.   
After that, click the mouse a couple times to create a connection  
description file (foo.connect) and then click on the telephone.   
Connecting means that you attach to the netinfo (advanced yellow pages,  
etc.) domain.  The systems act as though you were over ethernet.  There's  
a preferences switch that allows you to determine whether you want to use  
both B channels.

In the event that you can't go all the way with ISDN, the software is  
smart about asking a switch if it supports switch56 before committing to a  
line.  So you end up getting the most bang for your buck.  It currently  
doesn't use the D channel but does fully support the Voice channel.  Note  
too that the native soundfile format on the NeXT is muLaw encoded 8 bit,  
the same as the voice channel.

Now, if Ameritech would get off their butts and actually provide it as a  
service, I would be able to tell you more.

I'll be moving to Fairfield County, Connecticut soon, and my new company
will be buying me a computer for home.  If I talk them into getting me a
SPARCstation LX (which has ISDN support), will it do me any good?

I understand the basic concept of ISDN, but after reading this group for a
month I find myself lost in a sea of acronyms (as is generally the case when
one approaches a new computer field).  Is there anywhere I can find out the
basics, learn what I'd have to learn in order to get ISDN at home?

And if I had ISDN at home, what exactly would I have?  How robust is the
ISDN support from the phone companies?

Thanks for any help you can provide!  I'd bet there are lots of other people
in my shoes, as well...  I'd really like to become knowledgeable about ISDN.

It appears that it takes more than just a 5ESS switch to support ISDN. My

that it would take an additional $200,000.00 worth of equipment to provide

I've been through the same bit. A while ago I finally got through to a
guy (possibly the only guy) who knew anything about it, and had a nice
chat. Unfortunately, it was all hypothetical. BRI access, much less
residential, definitely seems to be beyond the event horizon, at least
down here in "high-tech" southern California. If anyone else has more
recent info (I saw the same article mentioned above), I would be very
interested to hear it.

There's been a lot of info bounced around about AT&T's switch, what does  
it really take to get a DMS to provide ISDN?  My local CO was rebuilt 5-6  
years ago and a local marketing rep said we got a new DMS.  Then he  
proceeded to try and sell me a T1 at $400 a month but he can't give me  
ISDN until the year 2000.  I said I'd take it if he'd put the other end of  
the T1 reasonably close to a backbone on the Internet.  Inter-who?....

Does anyone out there in Ameritech's 5 state area actually have ISDN?  If  
so, are you in Wisconsin Bell's service?  I can't seem to find anyone who  
knows or cares about providing services.  

Golly, all this and I have yet to ask for caller id....

Disclaimer: I'm not a 5E person, I'm a 4E person, so anything I say may not
totally reflect reality...

To support ISDN, a 5ESS needs to be at generic 5E4.2 or better; needs to
have ISLUs (ISDN Line Units) equipped in the switch modules, as opposed to
plain vanilla Line Units; needs to have whatever BRI feature package AT&T
sells; and, if ISDN is to be supported beyond the CO, needs to have SS7
support.  The first and third are software; the second and fourth are both
hardware and software.  I don't do pricing.

I would expect that LECs only count those digital switches which are indeed
capable of supporting ISDN BRI as an "ISDN Presence" in a CO.  So a 5E,
DMS-100, EWSD, GTD-5, or any other digital switch which was not currently
ISDN capable would not be considered an "ISDN Presence".

BRI is definately available in many Pacific Bell COs throughout California.
The only restriction (in addition to your CO supporting it) is that you be
within 18,000 wire feet of the CO.  It costs $29/month for 2B+D, for business
class of service.  (No residence service is available yet, but you can have
the business one installed in your home if you like).  There's no difference
in cost between voice and data calls - they all cost the same as regular voice
calls on a POTS line (since this is business service, local calls incur
message units).  Just be persistent with the "business" business office.  Or
you may want to ask for the large customer business office.  Their people are
much better trained, but usually don't deal with anything as small as a couple
of BRIs.  But they could probably get you in touch with someone that knows
about ISDN though.

   You've both probably heard of Illinois Bell's ISDN initial trials
with McDonalds(tm) Oak Brook "office campus" (started back in 1987, I
believe).  I've also written previously about AT&T's Naperville-area
office's use of BRI ISDN.  Even Wheaton College is using ISDN for some
applications.

   The AT&T Naperville/Lisle area uses an AT&T 5ESS(rg-tm) switch
operated by Illinois Bell to support several office buildings spread
over a several-mile area.  These total well over 10,000 ISDN BRI lines.
(The switch also supports much of the city of Naperville with analog
POTS/Centrex service.)  Besides the usual voice, voice-mail (AT&T's
AUDIX(tm) system), automatic calling-name&number, directory service
via keypad and single-button feature access, many terminals are equipped
with an Asynchronous Data Module (ADM) providing an 9.6/19.2 bps RS-232C
interface to an X.25 D-channel packet interface.  This allows a "dumb"
terminal or PC-with-emulator to have area-wide connectivity to any
other data-equipped terminal (or host computers using high-speed X.25
links).

   The January, 1991 issue of {IEEE Communications Magazine} has an
article describing all of the above, including the engineering/cost
trade-offs and several other applications.  A more technical view
is in the Nov/Dec 1990 issue of {AT&T Technical Journal}.

   Of course, while Illinois Bell is part of Ameritech, that doesn't
mean that Michigan and/or Wisconsin are capable of the same level
of ISDN support at the current time.  One could expect that the
business reps would have a higher level of ISDN knowledge than
the typical residential reps.

Al Varney - just MY opinion, of course
