What would make a frame relay PVC show as active for 10 seconds after router bootup or if the serial interface where forced administarively down then back up again. Internet traffic works for a few seconds then the PVC reports as deleted. I believe my hardware (cisco 1721 with T1DSU/CSU internal wic is not faulty. The provider is at a loss and wants to make internal changes on their side to different equipment.
Line protocol goes down. show frame pvc indicates no response from telco side. I am not onsite now so don't have access to the router.
