VIC2-2BRI-NT/TE for ISDN simulator

[balien]

Hello,

I am setting up a CCIE security lab environment.

Is it possible to use 1760 with one VIC2-2BRI-NT/TE for ISDN switch. I have two WIC 1 BRI S/T for the routers but I don't have ISDN simulator. It will be great if someone could suggest sample configs.

Thanks

I don't think that BRI cards supports back to back connection.

I made the folowing configuration 1BRIS/T ---- VIC2-2BRI-NT/TE on 17600 ---- 1 BRI S/T. The call is completed from first to second data BRI is completed but I think that the voice card interpreds the call as voice call so PPP negotiation can not be completed and the call is cleared with normal call clearing after 25 seconds.
