between the CO and subscriber premises | 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. |
| Product Overview
The DSL Xpert™ multi-layer analyzer (patent pending) breaks new ground as the only non-intrusive performance analysis solution for ADSL2Plus, ADSL2 and ADSL products. DSL Xpert™ is a modular tool designed for R&D and laboratory engineers engaged in the deployment of ADSL2Plus, ADSL2 and ADSL standard-compliant solutions. Cutting significant time from ADSL development, deployment, debugging and interoperability verification, DSL Xpert™ accelerates time to market and return on investment.
The innovative DSL Xpert™ analyzer verifies the interoperability of ADSL products offered by different vendors, and compares the performance of any combination of CO and CPE modems. DSL Xpert™ is a powerful tool for ADSL service providers (Telcos and CLECs), current and next-generation ADSL equipment (e.g. DSLAM, DLC, modem, router/gateway) manufacturers, and technology and chipset developers.
Leveraging patent-pending non-intrusive technology, DSL Xpert™ does not affect data transfer between the transceivers, thereby giving a complete and accurate analysis of ADSL product performance and interoperability. With its unique multi-layer probing capability, DSL Xpert™ focuses on the physical layer, and provides comprehensive analysis of data in any form - from analog samples to bits and messages. In addition, the system extracts the Upper Layers cells and packets and provides data, signaling and warnings of incompatibility with the various protocols from ATM through HTTP. DSL Xpert™ simultaneously presents downstream and upstream data and the connection between the two. A user-friendly software-based solution controlled by a PC, DSL Xpert™ has a feature-rich GUI that presents multi-layer information in convenient displays.
DSL Xpert is a proven test tool that has been used worldwide for testing numerous modems, which were successfully analyzed by chipset vendors, modem makers and telephone companies.
