I'm working on an ISDN project in University College Dublin in Ireland. We have
recently purchased two ISDN PC boards. These are the Datavoice SO ISDN PC board
manufactured by SCII Telecom in France which comes with an API called PCDEV,
and the other is the PCSNET ISDN PC card manufactured by OST Telecom also in
France.

Does anyone have any experience using either of these boards and the APIs
associated with them. Any comments would be much appreciated.

There is no commercial ISDN service in Ireland at the moment unlike most
other European Countries but a service will be introduced next year that will
comply with the "Euro-ISDN" standard. The prototype network that the national
Telecommunications company Telecom Eireann has at the moment runs French VN2
software.

I'm also interested in the forthcomming ETSI (European Telecommunications
Standards Institute) standard on a PCI (Programmable Communications Interface)
for Euro-ISDN which is currently in draft form.

Does anyone have any information on whether equipment manufacturers are
interested in implementing this standard when it becomes available or what is
likely to happen when this standard becomes available?

Dear John (and others),
	I can't really answer your questions quickly, but I will
look through my papers and get back to you. The EIUF has received
papers on this topic of APIs before.

	Are you aware that the next meeting of the European ISDN User's Forum
is going to happen in Paris next month? Will you (or anyone else
on the list) be going? The dates are 19th - 21st October.
The contact point is 

EIUF Secretariat, Ms S. Schwarz, FAX + 32 2 296 91 32

I and my colleague Neal Snooke will both be going.
We look forward to saying 'hello' to any list members
who may attend.
Bye for now...

>>How widely is HLC passed end-to-end?

Bellcore requirements (specifically TR-268 and TR-444) specify that HLC
should always be passed end-to-end.  AT&T's network supports transport if
it's received from a LEC.  I don't know implementation information about any

I try to avoid questions of "compatibility".  It is supposed to be passed
transparently by the switch, which means it *should* be consistent across
switch types, if only because the switch ignores it.  Of course, then you've
got to make sure the CPE on both ends agree.

They've been in CCITT and T1S1 standards since at least 1988.

Let's watch the terminology.  It's not B-channels that may be limited to
56kb/s, it's interoffice trunks.  B-channels are, by definition, at the
access.  B-channels must be 64kb/s, clear channel.  On PRI, the underlying
carrier must be B8ZS to provide 64k clear capability.  On BRI, the DSL
(Digital Subscriber Loop), whether ANSI-U or a vendor-specific interface, is
capable of supporting 64 kb/s UDI.

Interoffice trunks may in some cases only be capable of supporting 64kb/s
restricted digital information or 56kb/s.  In these cases, the access
protocol must permit rate adaption to 56kb/s.  The Bearer Capability will be
coded 64k UDI (per Q.931 Annex H), w/V.110/V.6 rate adaption to 56kb/s.

This was also the case with the previous (still current?) tied-to-Centrex
tariff. If you ordered ISDN at a residential location -- which required
also ordering Centrex at that location -- they made you get one POTS line
in your Centrex group (the rest could be ISDN) *unless* you already had
non-Centrex POTS service at that location that you averred in writing would
be kept active. Then they would let you get all-ISDN lines on the Centrex.

Sounds like the "new" PUC policy for single (non-Centrex) ISDN lines is
just a continuation of the old policy...

I'm pretty surprised by this myself.  My reaction is who wants to pay an
extra $100-200 for an external device or two (the NT NT1 is two large
pieces wasting space on my floor).

In particular, I don't (yet) give a hoot about the passive bus.  I guess
I can see why some Phone Phreaks might want the passive bus, it looks like
a home LAN for your native ISDN telephones, but I can't see that as being
a large part of the user base.  What really exciting things can I do with
an ISDN phone that I can't do with beefed up POTS service and fancy phones?

I want my LAN at home to be a real LAN (eg ethernet or localtalk, or even
token ring), not some one-or-two-terminal-at-a-time thingamajig.  And I
want my ISDN connection to be a portal from my home LAN to the Internet
(which it is doing nicely now).

So, I must be missing some obvious Hot Things I could do with this
passive bus besides warm my cats (the giant NT1 boxes are good at that ;-).
Maybe someone can enlighten us?

Huh?  I read "additional equipment" to mean a battery, a float-charger, and an
automatic cutover switch.  Ignoring the obvious and requiring a second separate
POTS line is just the sort of "solution" I'd expect from a government office,
though.

Believe it or not, we have earthquakes in the midwest too.  I was planning to
insist on battery backup if-and-when I switch to ISDN.  I can't believe it
isn't just built into the power supply as a matter of course.  It's not that
expensive.

Subject: Does ISDN use std phone numbers?  and what about forwarding?

Organization: Galloway Research
Originator: johng@godzilla

If making a 2B+D ISDN call, do you just pass in (somewhere) a normal
7 or 10 or 11 or whatever digit phone number?  

If so, then can a regular POTS phone line be forwarded to an ISDN line
and hence forward an ISDN 2B+D call?  The final target of the call would
of course have to be within whatever area was being served by ISDN for
a 2B+D 128Kbps call, but you could make a 1B 56Kbps voice call to any
other ISDN site.  With the possible onset of residential ISDN tarrifed
just like POTS (i.e.  a free unmetered zone sourrouned by metered zones),
forwarding becomes interesting, just as it is with analog lines.

Can ISDN lines be arranged into a hunt group with a single number getting
any of N lines?

   Bellcore's TR-NWT-000972 {Call Forwarding Subfeatures: Switching
System Requirements Using SS7} states that received codings of the
User Service Information parameter (the SS7 re-named version of
Bearer Capability) that are inappropriate for a non-ISDN calling
party should not be forwarded.  Though somewhat convoluted, the
TR does cover most of the loose ends not mentioned in TR-TSY-000444,
such as forwarding interworking between MF and SS7.  Note that
the wording doesn't limit non-ISDN forwarding to "speech-type"
calls - Switched 56Kb lines could forward appropriate ISDN-to-ISDN
data calls, and ISDN lines could forward non-ISDN data calls.

   Since an ISDN-to-ISDN call at "speech" or "3.1kHz audio" is sent
end-to-end as a bit stream, Digiboard's claim is fairly accurate.
Of course, such calls could hit non-digital facilities, encounter
an echo-suppressor/echo-canceler or even hit poorly-sync'ed circuits
without any notice back to the caller.  You also have to convince
the terminating ISDN TE to not convert the bit stream back to audio,
even though the ISDN switch tells it that it's a voice call.

Actually, it's quite useful in the exact present scenario that chuck

the reader to figure out what I do... ;-)

Actually, no.  On a multipoint interface (BRI with passive bus), the SETUP
is offered simultaneously to all devices on the interface.  Each device can
then examine the SETUP and reply with either a RELease COMplete w/cause =
"incompatible destination" or with a CALL PROCeeding message indicating
acceptance.  So for instance, when a 64k UDI call with a HLC of Group 4 Fax,
the voice set and PC card respond with a RELease COMplete, and the Group 4
Fax machine responds with a CALL PROCeeding.

Explicit subaddressing can also be used, but this requires the calling and
called party to agree somehow (e.g. through compatible equipment) on the
subaddressing scheme.

Disclaimer: this is taken from T1.607 (ANSI standard for DSS1, the US analog
of Q.931); it does not necessarily imply that anyone has actually
implemented this.  (Hey, I'm a PRI guy, I don't know from multipoint.)
