ADVA on Tuesday announced that Proximus is leveraging its Oscilloquartz timing technology to synchronize Belgium’s largest open mobile network.
The deployment enables Proximus to improve speed, coverage and reliability for millions of mobile users throughout Belgium, while also preparing its network for next-generation services. By deploying ADVA’s core grandmaster devices, access boundary clocks and its enhanced primary reference time clock (ePRTC) solution, the country’s incumbent telecommunications service provider is ensuring the levels of timing accuracy and resilience needed for 5G, broadcast and other time-sensitive services. The technology was implemented by ADVA’s partner Arcadiz Telecom, a leading provider of connectivity solutions across the Benelux region.
Proximus’s new nationwide synchronization network is built on the OSA 5440, an ultra-stable timing solution optimized for deployment in core networks and the OSA 5412 family of cost-effective, mid-scale synchronization devices engineered for deployment in a wide range of locations. It’s anchored by the robust and proven OSA 3230B ePRC cesium clock installed in two central sites. This supports high levels of frequency stability compliant with the strictest ITU-T standards and, combined with the OSA 5440, ensures long-term stability of UTC time. The extended stability performance of ADVA’s ePRC provides immunity against GNSS outages – a crucial requirement for mission-critical applications that should not rely on satellite-based timing alone.
Patrick Delcoigne, Director, network engineering and operations, Proximus
ADVA’s grandmaster clock and ePRC cesium technology empower us to meet key timing challenges. It enables highly accurate phase precision, enhanced stability and long-term protection from GNSS outages.
Jörg Urban, Senior Director, business development, Oscilloquartz, ADVA
The OSA 5412 Series and OSA 5440 support a smooth and cost-effective migration to next-generation phase and frequency synchronization. And with our ePRTC solution providing robust backup for GNSS, Proximus’ mobile customers can be sure of high-quality, uninterrupted services with no loss of performance.
