1. the 2 2620 connected back to back over the 2 xT1 (this means 2 connection in parallel) and try FR multilink configuration
2. you can try hub and spoke with one 2620 and hub and the other 2620 and 1721 as spoke
3. you can transform one of the 2620 in FR switch and do the necessary FR routing on it; then you connect to the 2620 FR-switch the other 2620 and the 1721 and try FR map dynamic (inverse-arp for example)
This is what I can thing of right now. It should be enough to test FR. The best would be to have a FR switch (or router with 3 T1 interfaces) and connect all the routers that you have now and try different scenarios like the one above. But with what you have is fair enough to be very familiar with Frame-Relay.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
