An improved structure of a handle for a re-writing device is disclosed. Triggered by service related network fault event, a key table comprising at least one key type is determined, based on a focus target record and related to the network fault event is determined, which key table is used in the step matching the at least one key with record data sets in determined Management Subsystem DataBases. The terminal shield substantially shields the soldering segments of the second terminals and prevents electromagnetic interference so that transmitting high frequency signals on the second terminals is stable.
