Hi,

My goal is to use 2 aux ports (possibly on 2610's) to practice
Dial-on-demand. Instead of using ISDN WIC and ISDN simulator, is it
possible to just use the 2 aux ports? Sample config would be nice.
Thanks!

You could use a roll-over cable to make it work.

I've got it working a few months ago.
I did it something like this. You could try to copy paste it. Don't know if 
it truly works. You can't really dial with it.
If you want to dial, you should try to get a home-phone central (?) here in 
the netherlands we have a device called a homevox (you can connect 5 phones 
(or modems) to it. I used it for my BCRAN exam. You can connect two modems 
to your routers the normal way, and then use some standard phonecable to 
connect the modems to the homevox, et voila, you have your own internal 
telephone network.

Here's the config. I think this worked for me. You could try it.

conf t
line aux 0
speed 38400
flowcontrol hardware
transport input all
int async 1
ip add 192.168.0.1 255.255.255.0
async mode dedicated
no shut

or you could use two modems if you have two phone lines, much more
realistic. DDR on a back-to-back cable doesn't really teach you
anything.

You can get some good dial on demand practice, but you need to be
aware that async DDR and ISDN DDR each have their own foibles and
bugs. I have no idea what you need for whatever certification test,
but in the real world you'll need to know both. There are sample
configs on CCO and on my website and all over the web.

You'll also find that the bugs differ with the IOS release and
hardware platform. For example, I working on resolving a bug right
now in 12.3 where dialer watch on the AUX port fails to dial. Its
a little tricky because the Async dialer watch is backup for a
56K ISDN link which is backup for 128K MLPPP ISDN which is backup
for a T1. If all links are dead, the async port will dial until
it connects. But any time the async call drops, there is a high
probability that the router will not try to call again!

Just for grins, consider the following: The failure only occurs with IOS
12.3, IOS 12.2 works just fine. The failure does not occur on a 17xx
router, only on a 26xx. The failure does not occur when using a
WIC-1B-S/T in the 2610, only with a WIC-1B-U (guess which my ISDN
emulator requires and which is used in production...).

Good luck and have fun!

I know,

So i adviced him to try to find something like a home telephone central. 
Like an el-cheapo homevox (about 30?) connect your modems and you can dial. 
It's got 5 ports so you can dial to multiple locations.

I guess you also have things like that in the USA.
But, if you haven't got anything, you could use a back-to-back to at least 
connect the two via an AUX port.

:)
