Cisco ISDN router as CPE

Hi:
I have two Cisco 800 series routers, each with ISDN U interfaces.
Is there any way I can setup one of these as DCE, so that the two
routers can talk to each other in the lab?


Thanks,

Tony

I am pretty sure the answer is no. You need an ISDN
simulator or even a PABX. Loads of the latter are being
ripped out of offices large and small as people
move to VoIP.

e.g.
http://shop.ebay.com/i.html?_nkw=isdn+simulator
http://shop.ebay.co.uk/sis.html?_kw=...+pabx+heymo t
These are random example searches.

Or of course Dynamips may suit your purpose.

Alternatively, the OP may like to try an ISDN card in a PC, as some can be
switched between TE and NT mode.

The OP would have to find a card that did SWITCH/CentralOffice emulation.
If he could, then the second challenge would be to find an old PC which will
work the the (old) card. PC architecture has changed over the years, and
these older cards just don't work on newer platforms. Then there's the
driver issue.....
It all makes you realize that the price for a postage stamp isn't all that
bad after all.
All the best and enjoy summer !

OK, thanks for all the info.
This is just for my own testing and studying, and it sounds like
waaaaaaaaaaaay more trouble than it's worth.
I'll stick with the router simulators for now.

Thanks.

ISDN has ben removed from just about every cisco cert, anyway, so you're not
going to miss anything.

Oh, they'll miss all the joys of trying to get the LEC to understand
that their switch is yet again misprovisioned for a BRI data service,
and to try to find that one tech that understands what ISDN might be and
that can make it work again in the LEC's switch.

Although there is some of that with PRI termination, but it seems to be
regulated to just matching up the number formats and strange callerID
settings now.

Well, if you want to get into voice then there is no harm in
playing with ISDN since ISDN PRI is still what telcos use for
end user provisioning (well for decent sized businesses).
One day I am sure it will all be over ethernet. Unless
someone comes up with a better idea.

For data networking, it is all gone - more or less.

ISDN simulator is VERY easy to use. PABX, no idea,
but how hard can it be?
