Abstract: A centralized restoration system and a distributed restoration system for restoring a network are integrated. Trunks within the network that have failed are first processed by the distributed restoration system to attempt restoration of the failed trunks. Trunks that cannot be restored by the distributed restoration system and trunks that are designated for restoration by the centralized restoration system are then restored by the centralized restoration system. The centralized restoration system and distributed restoration system communicate to keep each other aware of their respective actions. Mechanisms are utilized to prevent conflict between the two types of restoration systems. The integration of the two types of restoration systems causes high-priority trunks to be quickly restored by the distributed restoration system and lower-priority trunks to be restored by the centralized restoration system to balance the workload of restoration.

Abstract: An automated calling system includes a database comprising phone numbers and one or more data fields associated with each phone number. Phone numbers (callees) in the database are selected based on the data fields associated therewith.

Abstract: A klystron tube for amplifying signals at microwave radio frequencies utilizes an electron source for emitting electrons through a field focused by a high energy magnet in the RF section of the tube. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. The multistages of the depressed collector are connected to high energy voltage sources of different potentials. The klystron tube with the multistage depressed collector is uniquely used here for the first time in a ground based satellite or terrestrial communications system.
