A method for enabling recovery from concurrent failure of a plurality of storage devices in a storage array is disclosed. A chalcogenide material layer is between the first and second electrodes and a tin-chalcogenide layer is between the chalcogenide material layer and the second electrode. If the current mode of the mobile communication terminal is not the traffic mode for providing the HDR service, a supply of the battery power is blocked to the second RF module and the signal processing associated with the first RF module is performed. The termination modules hold fiber optic modules with front termination locations. Further, the social network itself can be displayed to any number of degrees of separation.
