DSL Data and IP Services Qualification, Provisioning and Performance Testing

DSL deployment continues to accelerate throughout the world as service providers strive to quickly sign up as many customers as possible to head off competition from alternative broadband suppliers.

The concern is that once a consumer is lost for broadband they may be lost for all services, including voice. Ongoing support costs must also be minimized as the deployment of DSL lines, and new services such as IPTV and VoIP, expands throughout the network.

Tollgrade’s Celerity® product line helps the service provider address these needs by providing a complete set of DSL testing solutions. These solutions are available today with Celerity, currently being used for qualification and service assurance for 60 million broadband lines.

Unique, Patented Technology

Celerity copper line test applications gain access to the copper loop through the standard voice switch test bus. There is no need for expensive re-wiring of circuits for either pre-qualification or in-service testing. Celerity can test through test access matrices as well for non-switched lines such as G.HDSL or unbundled loops.

One Test Head

All Celerity applications use a single measurement unit deployed in the exchange. The LDU 100 need only be deployed once to support broadband testing needs from qualification through service assurance. The flexible design of the LDU 100 ensures that today’s test requirements are met with a single test head while providing a platform to solve tomorrow’s needs.

Scalable Solution

The Celerity product line is designed to support high-volume DSL operations covering millions of lines. Tollgrade, with its more then 30 years of experience, has systems that test more than 150 million voice lines and 60 million DSL lines passed worldwide.
