Teradyne Announces LDU 50 For Test Of Next-Generation IP Networks

Deerfield, IL -- Teradyne announced the worldwide availability of the Loop Diagnostic Unit (LDU) 50. The LDU 50 is the Broadband Test Division's latest test unit providing qualification, provisioning and service assurance testing of next generation access networks. The LDU 50 supports local loop testing in exchange-based applications as well as in the extended temperature environment of remote cabinet applications (DLC, BBDLC, MSAN and FTTC), including those deployed in support of new IP networks. First deployment of the LDU 50 occurred last year in a large North American carrier, allowing them to extend their 4TEL(R) system to test lines fed from newly deployed soft switch remote cabinets. Subsequent deployments are proceeding for North American and European customers.

The LDU 50 is a DSP-based test head leveraging technology from its predecessor, the LDU 100, which has over 19,000 installations across Teradyne's worldwide installed base of 150 million lines. The LDU 50 supports all current 4TEL, 4TEL II and Celerity(R) functions and includes extended 5MHz wideband measurement capability for provisioning and service assurance testing of the copper plant to support broadband technologies (xDSL) and services (VoIP, IPTV). The LDU 50 also supports a services testing upgrade to provide an integrated physical and logical broadband test solution that fits into a single 1U test head.

With the LDU 50, network operators are able to extend their automated qualification, provisioning and service assurance testing capabilities to environmentally rugged locations, including fiber-fed remote cabinet installations. The LDU 50 has CE and NEBS certifications for support of worldwide market application.
