Two cautions: when I last tried it, about a year ago, an Ascend
Pipeline 50 talking to a Combinet CB-900 PRI interface got
IL checksum errors that do not appear when both ends are Combinet
boxes. I think it's a bug in Van-Jacobson header compression.
Also, a Pipeline 50 talking to a CB-900 reproducibly but gradually
corrupted and crashed the CB-900. Both of these bugs could be
fixed by now; the local ISDN support folks haven't encouraged me
to find out. :-)

Might want to grab the latest P50 binaries from Ascend.
I'll probably do same during Christmas.

Nice though they are, a Pipeline 50 is a bit too expensive for my
home network. In fact the Pipeline 25-Px is too pricey, but a really
neat product.

I would recommend getting an ISDN<->Ethernet Router, since plan 9 supports
ethernet already. In the US, an Ascend Pipline 25/50/75 would do the
trick, although I'm not aware of their status on EuroISDN... I would
assume they make a EuroISDN product tho...

I had assumed that the biggest battle in installing ISDN in the UK
was going to be persuading BT to do it, and writing the cheque
afterwards.
Not so. Selecting a decent PC card and getting the technical details
for it seems to be the problem at the moment.
Anyone out there got any experience/suggestions to pass on? There's a
Plan 9 driver in it.
I'm looking for
1. A PC card, preferably PCI but ISA will do.
2. From a manufacturer who will give/sell me a technical manual
3. With a EuroISDN stack
and optionally
4. An on-board V34 modem.
The only card which fits this so far is a thing called an Elsa
PCF/Pro, but I have great doubts that I could get a manual.

At variuos places in the manuals, ISDN is mentioned as supported media.
Any plans and comments?
If not, anybody interested? We intend to port our isdn drivers and
PC/S-bus/what..
