Tollgrade Communications, Inc. (Nasdaq: TLGD – News), a leader in the communications test and management industry, was awarded, through in-country partnerships, two significant international projects to supply its multi- layered testing solutions for country-wide networks. These awards follow extensive competitive technical reviews and include a full suite of Tollgrade’s DigiTest® test hardware and LoopCare(TM) software for comprehensive testing of IP triple-play services in advanced DSL access networks.

The projects are expected to include upgrades to Tollgrade’s DigiTest EDGE® multi-layer broadband test system, as well as new deployments of the DigiTest HUB(TM) next generation central office test platform, and DigiTest ICE(TM) designed specifically for deep-fiber DSL networks.

Upon completion of the agreements for the commercial terms for these projects, Tollgrade could begin to see the benefits from these awards during the first half of 2007. Together, these project awards are estimated to amount up to $14 million.

“These are significant wins for us because they validate our newest solutions for emerging and soon-to-be prevalent deep fiber networks being deployed by leading telecommunications service providers who intend to offer a variety of competitive IP-based services such as Voice-Over-Internet-Protocol (VoIP) and IP Television (IPTV),” said Mark Peterson, president and CEO of Tollgrade. “Further, these international assignments confirm that our newest DSL and IP testing solutions are competitive, offer an attractive end-customer business case, can efficiently augment a customer’s centralized service assurance platform already in place, and can be an industry prototype for implementing a network-wide deep-fiber IP service assurance solution,” added Peterson.

Among the Tollgrade testing solutions being deployed in these projects:

– Tollgrade’s LoopCare Test Operations Support System (OSS) is a leading loop test and management system and is testing more than 160 million access lines worldwide. Domestically, every Regional Bell Operating Company (RBOC) and many other leading local exchange carriers have chosen LoopCare for their loop testing.

– The DigiTest EDGE Broadband Test Platform is intended for use in the evolving broadband network edge. The currently deployed DigiTest EDGE is a powerful multi-layer test and management solution used to accurately qualify potential customers for broadband services, verify provisioning prior to service activation, and isolate multi-layered network faults.

– The DigiTest HUB is designed to support multiple testing and assurance environments within the evolving central office. As with DigiTest Edge, it addresses emerging broadband testing requirements, but also retains interfaces to legacy equipment. This unique feature allows for a truly seamless migration from traditional to packet-based delivery of services, allowing service providers to continue automated, mass-market processes to cost-effectively maintain the level of quality consumers expect.

– The DigiTest ICE, when generally available, will be Tollgrade’s newest addition to the DigiTest product family. It is a multi-layered broadband platform that will be optimized to test High-Speed Internet, VoIP and IPTV service at ultra-low-line-count DSLAM locations.
