Japan Electric Corporation and ADVA will jointly deploy time synchronization solutions for Telkom Indonesia, the largest fixed network operator in Indonesia, to help the operator prepare its transmission network and provide time-sensitive 5G services nationwide.
The monetization of new services such as ultra-low latency applications is the key for mobile operators to build momentum in the 5G era. In order to meet the expected demand of mobile operators and partners to use Indonesian telecom services, the company is improving the timing accuracy of its transmission network.

NEC and ADVA will provide a solution that supports the “precise time protocol telecommunication configuration file for phase/time synchronization, and has full timing support from the network” (PTP G.8275.1/2), which is recommended by the International Telecommunication Union (ITU) for 5G network. The network will further provide excellent customer experience for densely populated urban areas, including Jakarta and other central cities. Time synchronization will also achieve a flexible architecture to adapt to the unique needs of each region served by operators.
Gil Biran, general manager of ADVA Oscilloquertz, said: “Through close cooperation with NEC, we are helping to ensure that Indonesia Telecom can achieve highly reliable and accurate 5G timing. Our PTP master clock technology will provide important backup for synchronization based on GNSS, and provide stable and accurate timing from the core to more and more edge positions. NEC’s team works with us to exceed expectations and help customers achieve success. We will jointly bring the future to Indonesia Telecom’s 5G network The reliability and stability required for high-bandwidth, ultra-low latency services.”
For more than 30 years, NEC has been a trusted partner of Indonesia Telecom, providing end-to-end operator-level project management services from consulting, design and implementation to operational support, and utilizing its nationwide service coverage across many islands. Based on the extensive understanding of the operator’s network and the experience of deploying time synchronization solutions globally as part of the 5G xHaul conversion service, NEC will lead the system integration of the entire project.
Hideyuki Ogata, General Manager of the Service Provider Solutions Department of NEC, said: “NEC is honored to expand its partnership with Indonesia Telecom. With our global alliance partnership with ADVA and its industry-leading technology, we believe that this project will take another step in the development of reproducible industry best practices and bring an inspiring new customer experience for 5G networks.”
