    摘要： A system and method for assigning attributes to XML document nodes to facilitate their storage in relational databases and the subsequent retrieval and re-construction of pertinent nodes and fragments in original document order is provided. Since these queries are performed using relational database query engines, the speed of their execution is significantly faster than that using more exotic systems such as object-oriented databases. Furthermore, this method is portable across all vendor platforms, and so can be deployed at client sites without additional investments in database software.

    摘要： A transceiver module is configured for insertion within a cage. The cage has a cage latch that retains the transceiver module in the cage. The transceiver module has a housing configured to receive any one of at least two different release mechanisms. Each of the release mechanisms is movable between a first position and a second position, wherein the cage latch is not deflected when the release mechanism is in the first position, and wherein the cage latch is deflected when the release mechanism is in the second position such that the transceiver module can be removed from the cage.

    摘要： A technique for estimating distances and the nature of irregularities and faults on a telephone subscriber line is disclosed. Reflected test signals are measured as a function of frequency. The measurements are compensated for variable propagation velocity and variable line attenuation and then weighted before transformation with the Fourier transform. The amplitude and phase of peaks in the spectral domain identify the distances to the irregularities and the magnitude and phase angle of the reflection coefficients.
