Telecom Assurance Using Test Call Generation

Our test call generation tools help communication service providers (CSP’s) to assure revenues, manage margin performance, monitor network service performance and identify technical fraud. By assuring these key areas, a CSP can ensure service delivery, reduce costs, increase profit margins and exceed both regulatory and customer requirements.

Our Telecom Assurance Pedigree

We have been deploying and supporting test call generators (TCG) in the telecoms industry since 1982. We design, build and test them ourselves at our headquarters in the heart of England in Derbyshire.

Our engineers have walked the walk. Fielded more than 70 concurrent teams, driven more than a million miles, walked football stadia, airports, shopping malls, hospitals, royal quarters and private prime ministerial residences.

As part of our dedication to both accuracy and quality we have been BABT TÜV SÜD and NQA ISO 9001 accredited for over 10 consecutive years.

We are committed to looking after our future and future generations! That is why we have invested in sustainable solar energy in order for us to be able to offer Carbon Negative test call generation from our headquarters. Swap to our TCG services to reduce your carbon footprint.

Our Telecom Assurance Innovations

Our test call generators have a market-leading accuracy of ±100 milliseconds and ±1 byte. This unrivalled level of accuracy reveals the true behaviour of the OSS/BSS such as timing, metering and rounding. Open up previously untapped revenue opportunities by reviewing the business rules in place and creating business cases for revenue optimisation.

We have designed our TCGs with flexibility in mind. Capable of mobile (2G, 3G, 4G, 5G), VoLTE, M2M, broadband, converged voice and standard fixed line test event generation. They are simple to install – just add power.

Worldwide Distribution

We have carried out over 3,000 projects over the past 3 decades, across 6 continents (one continent was just too cold for us!) and have delivered over 8,500 pieces of test and measurement hardware across the globe.
