T-Systems, a wholly owned subsidiary of the Deutsche Telekom Group (NYSE: DT), and Convergys (NYSE:CVG), announced today the signing of a six-year Infinys [tm] billing services agreement. The agreement includes licensing Infinys billing and rating software, purchase of professional services, and the ability for T-Systems to re-sell Infinys in Europe, Middle East, and Africa (EMEA).

The agreement calls for Infinys billing and rating software to replace certain legacy billing applications in business units of the Deutsche Telekom Group. T-Systems currently manages and operates the legacy Billing applications for the Deutsche Telekom business units T-Com (7.3 million broadband connections in operation and 35.6 million narrowband connections) and T-Online (11.67 million customers).

“We evaluated many alternatives, but chose Infinys from Convergys for The upgrading of our legacy billing applications. The Infinys software will enable us to innovate in the market while lowering our total cost of ownership. We also plan to bundle Infinys into our T-Systems solution portfolio and offer it to clients outside the Deutsche Telekom Group,” said Olaf Heyden, member of the Executive Committee and Head of IT Operations at T-Systems.

“We are very excited about the opportunity to work with T-Systems. Its choice of Infinys is further evidence that Convergys provides a superior solution for our clients and is gaining widespread acceptance in the global marketplace. This is the largest billing agreement ever for Convergys in the EMEA region,” said David Dougherty, president and chief operating officer of Convergys.
