ADVA has launched a new software upgrade and introduced additional hardware designed to help mobile network operators meet 5G sync requirements.
With enhancements to the OSA 5420 edge device and the OSA 5430 and 5440 core solutions, ADVA’s Oscilloquartz technology brings better accuracy to synchronization networks. It enables a seamless transition to ePRTC and emerging PRTC-B specifications while supporting legacy interfaces for frequency synchronization.

In addition, transparent and boundary clocks with tighter specifications assure precise timing delivery to base stations. The upgraded portfolio enables MNOs to achieve the highest levels of precision and reliability from the core to the edge, maintaining legacy composite clocks while supporting new timing requirements.

“With our technology, network operators can keep their legacy services up and running while cost-effectively achieving the extremely stringent timing requirements of 5G,” said Gil Biran, general manager, Oscilloquartz, ADVA.

ADVA’s core synchronization solutions, the OSA 5430 and 5440, come with upgraded software and expansion cards. The modular design of the hardware makes it straightforward for operators to build systems that address their individual demands, selecting interfaces and line cards to meet their exact needs.

These solutions, as well as the OSA 5420 Series, feature firmware that supports the ITU-T’s newly specified boundary clocks, class C and D. With their enhanced timestamping capabilities, the devices distribute time with accuracy better than 5 nanoseconds.

By adding a line card, operators can achieve precise synchronization of legacy network architectures based on PRCs, SSUs, composite clocks and NTP. The OSA 5430 and 5440 support accurate multi-band, multi-constellation GNSS receivers, engineered to overcome inaccuracy caused by ionospheric delay variation, says Nir Laufer, senior director, product line management, Oscilloquartz, ADVA.
