    摘要： Component malfunctions in passive optical networks (PON) can increase bit error rates and decrease signal-to-noise ratio in communications signals. These faults may cause the receivers of the signals, either the optical line terminal (OLT) or optical network terminals (ONTs), to experience intermittent faults and/or may result in misinterpreted commands that disrupt other ONT's communication, resulting in a rogue ONT condition. Existing PON protocol detection methods may not detect these types of malfunctions. An embodiment of the present invention identifies faults in a PON by transmitting a test series of data patterns via an optical communications path from a first network node to a second network node. The test series is compared to an expected series of data patterns. An error rate may be calculated as a function of the differences between the test series and expected series. The error rate may be reported to identify faults in the PON.

    摘要： A method and apparatus for providing for arbitrary definintion of groups in a data communication network management system. Groups are added, modified, merged, deleted or displayed as desired by the user so that all members of the arbitrarily defined group can be addressed as a group, for example to do a self test and report results. Collectives can be defined as members of the group and the collectives can be unpacked at the time of issuance of a command rather than at the time of creation of the group so that changes to the collective are reflected as changes to the group automatically. Provision is made for creating groups which are commonly desired and significant group configuration activity is logged to either a printer or a file.

    摘要： A spear structure is defined by an elongate truncated conical body formed with a forward section and rear section intercommunicated by a frangible hollow sleeve arranged for separating the forward section relative to the rear section upon impact. A spring member directed through the sleeve and secured at its upper and lower distal ends to the forward and rear sections secures the forward and rear sections together upon such separation to preserve the rear section for reuse.
