Systems and methods for time series data error detection, correction, and transformation may detect gaps and anomalies in time series data, such as from a meter device, and may correct the gaps and adjust the anomalies prior to long-term record storage. Data forecasting may be used to correct the errors in the time series data. The error corrected data may be regarded as an actual set of time series data and become a base data set against which additional heuristic projections are generated. In addition, the time series data may be transformed into any number of physical and virtual device hierarchies that represent the underlying data source configurations, and may then be stored in an analytical database for further analysis. The hierarchies may be irregular and may change over time.

A swapping utility enables directional commands from a graphic user interface and / or keyboard to be utilized to swap data items associated with lists, tables or other series of data items. Upon receipt of both a directional command, e.g. up, down, left, or right, and a swap command, the utility uses the current position of the cursor or a selected entity to identify a first data item to be swapped and the relative direction thereto to identify a second, adjacent data item to be swapped. If both identified data items are of the same data type, their respective contents are exchanged within the ordered list or table without the need to cut and paste the content. In alternative embodiments, multiple adjacent data items may be swapped, or, in an embodiment which utilizes multiple selection icons, single or multiple nonadjacent entities may be directly swapped.

Component malfunctions in passive optical networks (PON) can increase bit error rates and decrease signal-to-noise ratio of 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 optical network node to a second optical 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. Through use of the embodiment, network faults can be identified and optionally automatically corrected, saving a network service provider from expending technician time and maintaining an operating state of the network.
