Ahmed,

Thanks mate for the input. But I am not looking for just back-back
connection. I want to be able to dial out from one router to the other (dial
in demand).

The link provided talks about just back-back permanent connection. I need
dial up connection.

Example, I want to use this aux dial up connection as backup to other
interfaces (to simulate ISDN BRI links), which means that AUX under normal
circumstances is down but will DIAL remote end if primary serial goes down.

thanks

Please have a look at :

But ur roll over will not do the trick. for this u need a null modem cable.
In this doc. it is written that this is been done with roll-over cable....
yes this right as null-modem cable is also roll-over but with different pin
connections.
