ISDN simulator for dial-backup testing?

[voltron1011]

I have a Cisco 2621xm with 1 BRI-U interface and a T-1 DSU/CSU interface. I need to be able to test some dial-backup scenarios where the T-1 fails and the BRI dials up afterwards. I don't want to buy another ISDN line just for testing this. What are my options for simulators? Any ides? Thanks.

There should be lots of these on sites like Ebay - just do a search for ISDN simulator on there.

I bought the following one awhile ago off Ebay:

Hey Kisco, if my routers have an ISDN-U interface, does the simulator also have to be a U interface?

 

[KiscoKid]

Yes it the sim will need to be a U interface as well
