Continuous Real Time Analysis (CRTA)

 

Some events in the ADSL link may occur long time after the DSLAM and CPE modem have initiated and established their connection. Examples of such events are:

·         Reset of the ADSL layer

·         Disconnection of the IP layer

·         A message (with certain parameters) repeated multiple times in a specific protocol

·         Crossing a threshold of a specific parameter, like rate of an ATM channel

·         External trigger using the DSL Xpert system’s Command Line Interface

 

The CRTA module helps R&D and test engineers to track and solve such events by enabling real-time activity monitoring and statistics of very long sessions without a capture time limit.

 

The captured data and analysis are saved to a cyclic file. The user defines the file's size (in seconds), which becomes the captured “time-window” duration. The user also defines the trigger for stopping the capture. When the specified pre-defined event occurs and the capturing stops, the user may explore the recording and view the analysis with the usual DSL Xpert views for the events that occurred during the predefined time-window. The user can also define that the capture will continue for a specific length of time after the event occurred. In addition to the Showtime captured data just before the event, the Real Time Analysis provides the parameters associated with the initialization sequences for any Showtime phase that occurs in the time window.
