ISDN BRI U port connection

[TheodoreBe]

I have 5 Cisco 2611 routers in my home lab. Each one has an ISDN BRI U port and I am not sure what cable to use between them, and what configurations I will need to allow connectivity.

You will need an ISDN simulator to get connectivity.Why are you studying ISDN?Also don't you have WIC-1T's to T1 labs.

I am not really studying ISDN, I just want to be able to utilize these ports to have more options when laying out the topology of my routers. Is there some sort of ISDN crossover cable? And yes 3 of my routers have T1 CSU/DSU cards, I am using 2 of those ports.

No such cable!Only an ISDN sim can do this job.

Since there is no interconnection between the ISDN ports on my routers, is there another card that I could put into that slot, something like a 4 ethernet port card to allow me more options in setting up the topology?

Yes you can find some NM-1E or NM-4E ,may be expensive and hard to find.WIC-2T's or NM-4A/S should be cheaper.
