As a simplier troubleshooting technique try doing a hdlc connection
between r1 and fs and also r2 and fs. ie. don't use framerelay and just
define encap hdlc, (or no encap frame-relay) and define clocking on the
DCE end of the link.
If still don't get the links to come up and you can't ping between
r1 and fs and r2 and fs there likely is a hardware or cable problem.
