Me too, but I already have 2 POTS lines from different suppliers...

I am trying to set up a small network at home. 3 computers variously
running Win95, Win NT4W, Win NT5S EE beta, OS/2 v4, Linux (RH 5.1 and
Suse 5.2). Which of these is the Teles compatible with? The Teles www
site is still under construction.

The alternative to avoid OS compatibility problems that I was
considering was a combined standalone router and hub, but �400?

Masquerading for lans could be handy for me.

An offer I couldn't refuse... Thanks

I wasn't aware that compression was available under ISDN at all! Does
Demon do it? Do all TAs do it, or just some of them? What kind of
compression is it? Apart from the time it takes to connect, is there
much advantage to ISDN over a 56k modem? Is there a speed limit
somewhere at Demon or the home end which will even things out anyway,
like the serial port running at 115200bps?

Questions, questions. I don't expect you to answer all of them, but your
thoughts on the matter would be appreciated.

Thanks for your usual helpfulness Richard.  If I can find one I may well
try it.



For others reading this, note that the 44kbps claimed as likely on V90
modems is almost certainly a pipe dream if you have 2 lines. BT seem to
be fitting a device called a DAX in such situations and this limits the
line sped to 28.8 !!

I read about this in the September Internet magazine and then realised
why I could not get better than 28.8 myself even with a K56 modem to the
Demon Energis number and Ray Gwinn's SIO fitted.

I've just this minute been looking at the BT highway web pages
(http://www.homehighway.bt.com/)

I must admit, I'm a little tempted!! I suppose if you ignore
the startup charge, and consider the 40ukp inc 15ukp
free calls, it's really only about 15ukp more than a normal
monthly account!

I would assume that using a TA + In-joy would be relatively
straightforward?


Cheers
Chris

Thanks Richard.

I called BT HomeHighway and they have ten times the demand they were
expecting, and my exchange cannot handle it yet. The person I spoke to
knew nothing about BusinessHighway (using the same technology as HH) or
standard ISDN, so comparisons were not possible. Typical.

There's probably a HOWTO somewhere. I'll have a look. 
http://tsikora.tiac.net/i4l-faq/eng-i4l-faq.html
There seems to have been a glitch around kernel v2.0.30, otherwise it's
built into the kernel. NT5 isn't working here yet.

After my recent mega-upgrade session I seem to have lots of
486/mb/vlb/scsi bits left over, but no cases, or the room to have a 4th
(or 5th) computer. Perhaps I should replace the WinModem in Pav with a
Teles, though it will be running NT4 usually.

Mmm, no compression in OS/2 or Linux, and MS will charge a bunch for LAN
interface stuff. I looked at the Zyxel site recently and seem to
remember something about them doing MNP5 (?).

If that's without compression, that's good. Twice what I get (at 33.6kbs
currently).

So does the Teles card work as a serial port, (115k) or does it do
better than that (like a NIC does)?

I was thinking more about something I read a while ago which IIRC said
that the Ascends are limited to 115kbs, so that even with a 56k modem
and a highly compressable file you still only get 115kbs max. I could be
wrong though, and I don't know anything about Demon's ISDN equipment
limitations.

Only one question this time...

Thanks. That's given me something to think about once I've got all my
operating systems talking to each other over the network.
