Oscilloquartz Achieves Industry Breakthrough with Highest Capacity Modular Grandmaster Clock

New Product Features Unprecedented Scale with Support for over 3,000 Remote PTP Clients and will be Launched at International Telecom Sync Forum


Oscilloquartz, an ADVA Optical Networking company, today achieved an industry milestone with the launch of the OSA 5335 Modular Precision Time Protocol (PTP) Grandmaster. This is the first product of its kind to feature a modular design and extreme scalability at the same time. The OSA 5335 can support from 128 to over 3,000 remote PTP clients at 128 packets per second (PPS) - something that has never been achieved before. This new class of product will prove critical for mobile network operators (MNOs) that are deploying LTE-FDD networks today and are seeking to migrate to LTE-TDD and LTE-Advanced in the most cost effective and scalable way possible. Fully compliant with IEEE 1588v2 standards and the latest versions of ITU-T Precision Time Protocol (PTP) profiles, the OSA 5335 will be launched at the International Telecom Sync Forum (ITSF) 2014 and is commercially available today. 

“What we’ve achieved with the OSA 5335 isn’t simply an upgrade or an enhancement, it’s something radically new, something the industry has never seen before. It’s an entirely new approach,” said Gil Biran, general manager, Oscilloquartz. “By introducing a modular design to Grandmaster clocks, we’re showing the industry that there’s a better way to deliver precise and reliable frequency, phase and time-of-day information. It’s a more scalable way. It’s a more efficient way. The impact here will be enormous. The OSA 5335 can support over 3,000 remote PTP clients. This is a huge figure and something that’s never been possible, at least not until now. And when you combine this hardware with our scalable sync management software, you have something truly unique.” 

The OSA 5335 has been built from the ground up for the distribution of frequency, phase and time synchronization over packet-based networks. It provides software license based high-client capacity and a broad range of redundancy options for maximum scalability and redundancy. The OSA 5335’s modular design ensures that it can be configured to a MNO’s exacting demands, including the use of two Global Navigation Satellite Systems (GNSS), supporting local variations such as GPS and GLONASS. Delivery of such precise synchronization enables MNOs to meet rigorous Stratum 1 requirements without the need to install and manage external receivers or Cesium reference clock sources. The associated reduction in provisioning, operations and maintenance needs are significant, both from a cost and labor perspective. 

“The OSA 5335 completes the Oscilloquartz portfolio. It’s the final element to delivering a full end-to-end timing and synchronization solution. What’s more, it’s something truly unique,” commented Brian Protiva, CEO, ADVA Optical Networking. “The Oscilloquartz team worked side-by-side with key industry players to develop the OSA 5335. They listened closely to what customers wanted, they heard their frustrations and concerns and designed a new class of product, a new Grandmaster clock that can deliver so much more than ever before. And this isn’t a moment too soon. For MNOs, media companies, utility operators and other industries, the need for the OSA 5335 and its enormous scale is vital. We’re at the start of an exciting journey.”  

Oscilloquartz is exhibiting at the ITSF 2014 conference in Budapest and will host a reception on the first night of the event. During the conference, several of the company’s subject matter experts will share valuable insights into phase delivery and the evolution of network infrastructure. Presentations include “Phase Delivery in a Brownfields World” and “In Service Synchronization Monitoring and Assurance” by Nir Laufer, senior product manager, Oscilloquartz and “Smooth Evolution Path from Legacy to Next-Generation Network Synchronization” by Dominik Schneuwly, senior network consultant, Oscilloquartz.
