RA'ANANA, Israel, September 12, 2011 /PRNewswire/ -- Multi-layer analyzers for broadband access lines ensure successful service deployment and future readiness TraceSpan Communications, a leader in broadband analysis and monitoring solutions, is helping rural service providers improve their customers' quality-of-experience. TraceSpan's Xpert™ analyzers can passively analyze the access network during live sessions and ensure its utilization as an error-free pipe - a key condition for successful service deployment. In addition, these analyzers can measure the influence of crosstalk and other interferences on QoS and QoE to help the service providers develop and test means to mitigate these interferences. TraceSpan's analyzers for ADSL2Plus and VDSL2 networks have recently been selected by Calix (NYSE: CALX), a leading global provider of broadband communications access systems with a strong footprint in the rural service provider space. Calix is using the Xpert™ analyzers to develop their "Best Practice" concept for deploying IPTV services over copper. This concept is being implemented to deploy services with Calix's more than 900 customers, whose networks serve over 50 million subscriber lines in total. "TraceSpan has always been focused on providing revolutionary tools for broadband access networks testing and troubleshooting," said Dr. Hanan Herzberg, TraceSpan founder and CEO. "The growth in the rural service providers' networks, which is strongly accelerated by the US government stimulus plan, has given us an excellent chance to leverage our experience and work with Calix and their customers to improve their networks and services for the benefits of their subscribers." Rural service providers use both fiber and copper networks to deliver services to their subscribers, and each network technology introduces its own challenges. TraceSpan's family of Xpert™ analyzers provides solutions for both these types of networks. The Xpert™ analyzers are extensively being used by the majority of tier-1 telecom operators and manufacturers and have become the standard de-facto broadband access testing solutions in the market. The DSL Xpert™ and VDSL Xpert™ analyzers support the most advanced techniques for utilization of the copper networks, including bonding, vectoring and physical layer retransmission. The GPON Xpert™ is the leading real-time multi-layer GPON analyzer, which can analyze and troubleshoot the GPON network itself as well as the services delivered over GPON.
