Connecting to an ISDN BRI on a router from a PSTN line from remote site..!!

Friends,

I have a 1812 at HO with WIC1 BS/T Card, connected it to an ISDN BRI line.One of my critical remote location uses Leased circuit to reach my HO Router.But in case if LL goes down,some of the important PC's at the remote site should be able to dial to HO Router BRI Number using PSTN line, get connected and continue, ip address assigned from HO Router and access the application... Is any way available...

Hi Arnab.

You need to configure dial backup through AUX port. You need to connect a normal PSTN line to a modem which in turn is connected to your AUX port. You will have to configure a chat script which you can find in the attachmnet. The attachment is a working example in one of my routers.

You also have to create an ASYNC interface. Check that in the attached file also
