Forensic diagnostic capability including g.inp

Abstract

There is a need for a forensic diagnostic capability to facilitate a greater understanding of why xDSL transceivers are subject to otherwise inexplicable service interruptions during Showtime (steady state data transmission mode). In certain exemplary embodiments, diagnostic data from a previous Showtime is stored and then communicated to another transceiver and/or reported (or communicated) to a management entity. The stored diagnostic data can be used to determine why the service interruption occurred. In other embodiments, one or more portions diagnostic data from a last Showtime are stored. In additional embodiments, this diagnostic data is collected immediately prior to exiting Showtime and/or retraining (the 'last' data collected prior to exiting Showtime and/or retraining). Alternatively, or in addition, the diagnostic data can be collected during a current Showtime using a sliding window that covers the most recently received signals and communicated to another transceiver and/or a management entity during the current Showtime.
