Check the clock rate and cabling on both ends. If the clock rate specified
is different than what the module supports, then I believe the line will
come up and go back down. (For example, the WIC-2A/S cards only support a
maximum clock rate of 128K).

* Check cabling (are the DCE and DTE ends correct?)
* Make sure frame-relay intf-type is set correctly on both ends (and cabling
is OK)
* Check clock rate (set on the interface)
* Issue a "no shut" on all frame-relay interfaces on both ends of the PVC.

The question is that Caslow says on page-110 that if FR switching is
on, just enabling the encapsulation will bring up the PVC by using
inverse arp. I don't see that happening.
