Frame Relay Switch

I have almost completed a very basic CCNP lab. One thing I want to do it get a frame relay cloud/switch setup so I can work with it.

I found a plethora of good examples out there.. but leave me with one question. Can I use all the 56k DSU WIC i have to make the connections.

I am able to directly connect 2 routers with the 56k wic's and a home made cable.(and some quick configs) BUT.!! All the examples I found use a WIC 1T to connect the routers to the frame relay switch (router being a FR switch)

Any help out there?

Looks like I got it working. Getting some "funny" behavior.. but I think i just messed around with it too much.

So it looks like it can be done. Sweet.
