Continuous Real Time Analysis (CRTA)
Some events in the VDSL2 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 VDSL2 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. |

Product Overview
The VDSL Xpert™ multi-layer analyzer breaks new ground as the only non-intrusive performance analysis solution for VDSL2 products. VDSL Xpert™ is a modular tool designed for R&D and laboratory engineers engaged in the development and deployment of VDSL2 standard-compliant solutions. Cutting significant time from VDSL2 development, deployment, debugging and interoperability verification, VDSL Xpert™ accelerates time to market and return on investment.
The innovative VDSL Xpert™ analyzer verifies the interoperability of VDSL products offered by different vendors, and compares the performance of any combination of CO and CPE modems. VDSL Xpert™ is a powerful tool for VDSL2 service providers (Telcos and CLECs), equipment manufacturers and technology and chipset developers.
Leveraging patent-pending non-intrusive technology and following the overwhelming industry acceptance and tremendous success of the company’s flagship system, the DSL Xpert™ ADSL analyzer, the new system defines a class by itself. The VDSL Xpert™ does not affect data transfer between the transceivers, thereby giving a complete and accurate analysis of VDSL2 product performance and interoperability. With its unique multi-layer probing capability, VDSL Xpert™ focuses on the physical layer, and provides comprehensive analysis of data in any form - from analog samples to bits and messages. VDSL Xpert™ simultaneously presents downstream and upstream data and the connection between the two. A user-friendly software-based solution controlled by a PC, VDSL Xpert™ has a feature-rich GUI that presents multi-layer information in convenient displays.
VDSL Xpert™ is the only non-intrusive and unbiased testing tool that does not have VDSL chipset inside. As the only developer of xDSL non-intrusive protocol analyzers, TraceSpan gained worldwide recognition as an industry leader whose products are sought after and used by all major chipset vendors, modem makers and telephone companies.
