DDG provides professional services to cable, wireline and wireless operators, as well as enterprise customers, focusing on performance analysis and verification of voice, video, data, and wireless networks. Its global testing solutions, integrating advanced test instruments and applications from DDG's regional test sites, ensure reliable service support anywhere in the world, even in remote and hard-to-reach areas.
To conduct testing, we typically use products from leading test, monitoring, and workflow management equipment vendors. Our testing solutions cover a wide range of network performance field tests, including bit error rate testing (BERT), service activation verification, network performance assessment, and IP connectivity testing. We also strictly adhere to the RFC 2544 test suite, which is specifically designed to assess service-level agreement (SLA) parameters. By providing measurement data on performance availability, transmission latency, link stability, and service integrity, we help customers verify that the operating parameters of delivered circuits meet contract terms and conditions.
The final output of each site survey is not only comprehensive but also fully customized, ensuring the optimal solution for our clients' specific circumstances. Our dedicated on-site team collaborates closely with our central survey coordinator and project manager, who meticulously prepares survey deliverables tailored to the client's specifications. These include tailored graphical outputs and standardized, clear, and user-friendly documentation. Flexibility is a core characteristic of our service approach, enabling us to tailor reports and documentation to support our clients' daily operations.
