Abstract: A signal shielding box with a plurality of shielding covers is provided. The shielding covers are pivotally connected with a shielding case and cover one another so as to respectively conceal or expose the opening. A connector is positioned at the shielding case and is electrically connected with the wireless communication device within the shielding case. The connector is electrically connected with a measurement and analysis device out of the shielding case. The shielding covers are respectively opened and closed so as to expose and conceal the opening. Thus, a plurality of shielding effects are formed so as to shield and measure signals of the wireless communication device.

Abstract: In accordance with one embodiment of the present invention, a network element comprises a first subsystem operable to receive management transactions in a first management protocol and to map the transactions to a common management protocol. A second subsystem is operable to receive management transactions in a second management protocol and to map the transactions to the common management protocol. A common management information base (MIB) includes a dataset and a common interface to the dataset. The common interface is operable to access the dataset to process transactions received from the first and second subsystems in the common management protocol.
