JDSU Adds New Ethernet Features to Modular HST-3000 Handheld Field Tester, Including Support for IPv6

October 17, 2007 � JDSU today announced enhanced features for the HST-3000 handheld services tester, the most complete all-in-one access test platform available, including new features to support the rollout of IPv6. IPv6 is the standardized, next-generation IP protocol under adoption worldwide.

Milpitas, Calif., October 17, 2007 � JDSU today announced enhanced features for the HST-3000 handheld services tester, the most complete all-in-one access test platform available, including new features to support the rollout of IPv6. IPv6 is the standardized, next-generation IP protocol under adoption worldwide. The new features, available as a software upgrade, will be introduced at Light Reading Ethernet Expo in New York, October 15-17 (booth 416) and AFCEA's TechNet Asia-Pacific in Honolulu, November 5-8 (booth 505).

Originally called "IP Next Generation" (IPng), IPv6 is expected to replace the current IP protocol (IPv4). It supports quality of service (QoS) parameters for real-time audio and video and is designed to fix the shortcomings of IPv4, including data security issues. The HST-3000's new IPv6 features provide the ability to test IPv6 connectivity, throughput, latency and packet jitter. Tests supported include verification of stateless or stateful address auto-configuration; IPv6 ping; traffic generation; and the ability to receive, filter and report IPv4 or IPv6 traffic.

Developed in response to customer requests for greater Ethernet test ease-of-use, the upgrade to the HST Ethernet module includes an improved graphical interface (GUI) with fewer "button pushes" that enables users with limited test experience to conduct simplified pass/fail analysis. The upgrade also offers support for MPLS, Q-in-Q (also known as VLAN stacking), Layer 4 (TCP/UDP) throughput testing, and PPPoE. Language support is available in simplified Chinese, German, Spanish, French, and Turkish.

"The emergence of new data, voice, and video services comes at a time when service levels and reliable performance are the differentiating factors in Ethernet networks," said Dave Holly, senior vice president and general manager of JDSU's Field Service Communications Test and Measurement group. "The HST-3000 has always provided the most advanced and cost-effective solution for the full set of test applications required by field technicians and the features in this upgrade put additional testing power in the hands of field technicians."

The HST-3000 performs four automated tests that meet RFC-2544, a benchmarking methodology for testing Ethernet links: packet jitter, throughput, latency, burstability (back-to-back frames), and lost frames. RFC-2544 represents a baseline to verify quality of service, as defined in Service Level Agreements (SLAs).

About the HST-3000
The JDSU HST-3000 is a handheld tester that scales to meet the full depth and breadth of test applications required by field technicians responsible for access network service installation and maintenance. The all-in-one handheld tester has been adopted worldwide by telecommunications network operators because it provides a broad set of capabilities engineered for the rapid, reliable and efficient deployment of broadband services. The HST-3000 is the only handheld telecommunications service tester licensed to support Nortel's UniStim VoIP protocol, providing users the ability to troubleshoot and test the features and capabilities of Nortel's IP desktop telephones, and also provides licensed test support for vendor-specific versions of IPTV such as MSTV.

By adding ADSL2, ADSL2+, VDSL, VDSL2, VoIP and IPTV test options, the HST-3000 provides a comprehensive and industry-leading portable test solution for triple-play service deployments and extends its capabilities for installation and maintenance crews who are responsible for the turn-up and troubleshooting of these new services.
