Managing a plurality of Communication devices in an access network by successively establishing a temporary point-to-point layer two connection from a management server to each of the communication devices of the plurality of communication devices during a management phase. The spheres can provide clean and efficient carriers for introducing SAP into the cable during manufacturing. The carrier in which the product wafer determined as being failed is accommodated is regarded as a rework lot by the host computer. It is determined whether the first status report indicates a status different than the status indicated by the second status report. A lid assembly is provided that is selectively attached over the open top end of the container. The active area of the device is formed of trench devices having a thin gate dielectric on the trench walls and a thicker dielectric on the trench bottoms over the device depletion region.
