As part of the deal, Nokia Siemens will take over control of the operator’s Vivento Technical Services division with 2,000 employees and provide multi-vendor maintenance, systems integration, and installation services over the next five years.

Nokia Siemens has also signed additional contracts worth a combined 150m-euros ($214m) over the next five years to provide equipment and services, and has also been named a preferred partner for upcoming outsourcing and managed services projects.

The win is a coup for Nokia Siemens given that Ericsson has won a string of managed services contracts with Deutsche Telekom in recent years, including a six-year deal in August to operate and maintain its microwave network in Germany.
