Telesens

❓ CHALLENGE

DTAG requested Telesens for the development of an interim solution for processing and billing of the whole IP-traffic and DNS services of its Internet provider T-Online.

The biggest challenges of the project were the need to synchronize contracts with 62  customer service centers located throughout Germany and passing the bills in different formats into a variety of internal systems, inclusive mainframe-based ones.

✅ SOLUTION

A full development cycle starting from business analysis and ending with the maintenance of the system and the implementation of change requests for 5 years was performed by Telesens.

After the business analysis phase, Telesens proposed typing and parameterization of tariffs which allowed to reduce the number of unique tariff models from 10,000 to 5.  The proposed types of tariff models de facto became the DTAG standard.

❓ CHALLENGE

The operator had a lot of self-developed addendums to its billing system for pre-paid subscribers, about 200 medium-size applications developed using the JRM framework. The ad-hoc nature of these developments and lack of associated documentation resulted in unmanageable storage of executable modules and source code. The operator asked its system integrator, Atos Origin AG, for complete reengineering of this area in order to enable efficient support of the billing environment.

✅ SOLUTION

Telesens acted as a subcontractor to ATOS and was fully responsible for reengineering, documenting source control, and support of all JRM modules.

A functional specification was created for each module. Existing sources were compiled and checked against the live versions. A change management process for the JRM environment was set up. Refactored applications are in service during the last ten years and followed with support and change-requests-implementation by Telesens.
