    摘要: A method and apparatus are disclosed for testing susceptibility of a gate insulator in MOS and MIS devices to irradiation without use of ionizing radiation. The method consists of simulating the effects of radiation by applying a high magnitude, pulsed electric field to the device under test. An apparatus capable of determining the relationship between voltage applied to the device under test and the device capacitance is used to provide the desired susceptibility information.

    摘要: A method for providing dynamic allocation of trunk circuits of different classes of traffic having different bandwidths in a Digital Private Network Signalling System (DPNSS) link between two switching nodes is disclosed. The trunk circuits are grouped into trunk groups. Trunk Access Class (TAC) is a code used to differentiate different classes of traffic. In the switching nodes, a table exists which defines to which trunk groups access is allowed or barred by TAC whereby bandwidth (or trunks) in the DPNSS link can be allocated by class of traffic. The grouping of trunks into trunk groups and the table which allows or bars access to trunk groups by TAC may be altered from time to time in the switching nodes at each end of the link by management command, to vary the allocation of bandwidth between classes of traffic in the DPNSS link.
