TraceSpan's DSL Xpert™ Analyzer Supports G.INP

Industry’s leading real-time passive DSL multi-layer analyzer can now analyze and troubleshoot DSL lines with physical layer retransmission  

Ra’anana, Israel, December 16, 2010 – TraceSpan Communications, a leader in broadband analysis and monitoring solutions, announced today the release of G.INP support for its DSL Xpert™ analyzer.

G.INP, which has recently been standardized by ITU in the G.998.4 recommendation, is intended to provide enhanced protection against impulse noise or increase the efficiency of providing impulse noise protection (INP). This is accomplished with new techniques applying physical-layer retransmission.

DSL Xpert™ is a multi-layer analyzer, which provides a complete and accurate analysis of ADSL2Plus product performance and interoperability with no affect of the data transfer between the transceivers. With its unique multi-layer probing capability, DSL Xpert™ provides comprehensive analysis with various outputs - from analog samples to bits and messages. In addition, it extracts the upper layers cells and packets and provides data, signaling and warnings of incompatibility with the various protocols. The supported protocols range from ATM, through network layer protocols such as IP and IGMP, and up to application layer protocols such as HTTP, as well as TR-069. DSL Xpert™ simultaneously presents downstream and upstream data and the connection between the two. Its feature-rich GUI presents multi-layer information in convenient displays, and also allows automatic generation of exportable reports.

Now, with its new G.INP capability, DSL Xpert™ allows its users to verify G.INP compliance of their ADSL2plus equipment and chipsets, find and analyze problems related to G.INP prior to their field deployment, and troubleshoot such problems on live networks in the field.

"With the increasing use of DSL lines for IPTV service delivery, these lines must be capable of providing adequate service stability in the presence of impulse noise", said Dr. Hanan Herzberg, TraceSpan founder and CEO. "The G.INP standard is intended to assure this, but as every new standard it is also likely introduce new infancy problems. DSL Xpert™ can now help our customers troubleshoot these problems quickly and easily using automated or manual testing, thus minimizing downtime and assuring service reliability and customer satisfaction".

The DSL Xpert™ G.INP is a new software module which must be purchased separately. As a limited-time introduction campaign special terms for its purchase are given to all of TraceSpan's customers who have a maintenance contract for their DSL Xpert™ systems and to those who will renew it by the end of 2010.
