Solving the Ultimate Sync Challenge
Kenneth Hann, Senior Director, Research & Development, Oscilloquartz
|Synchronization is now an enabler for many high-value services. In the case of new mobile technologies, it’s even a prerequisite for service availability. Quite simply – if you don’t have sync you don’t have service!
Synchronization enables business and if ever the flow of dollars is stopped someone will pay. With this kind of value attached, it’s no surprise that there’s so much interest both in the provision of synchronization as a service and in monitoring the service quality.
Delivering and Monitoring Time at the Same Time
Let’s consider operator “A”, who uses Oscilloquartz grandmasters to provide synchronization throughout his network. It may also install Syncjack™ equipment to provide independent monitoring of the synchronization network. Operator “B” may purchase a synchronization service from “A” and may choose to install a separate monitoring solution to verify his synchronization service meets SLA commitments.
The Poacher and Gamekeeper
The basic problem here involves independence, credibility, and cost effectiveness. In an extreme case, operator “A” uses a device to deliver a service to operator “B” and operator “B” uses a separate, but similar device to monitor the delivered quality of that synchronization service.
The use of additional equipment for service monitoring ultimately increases the cost of the service. Especially so if monitoring is installed and managed separately by both the service provider and the service subscriber. So, what can be done to provide monitoring, traceability and security direct from the synchronization delivery network?
Successful Timing in the Brownfield
Assisted Partial Timing Support Does Double Duty
Should GNSS fails, PTP maintains the local time base, using the asymmetry compensation values previously calculated. So when things are going well, you have two sources of timing information GNSS and PTP slave.
In fact, all of the following are in the same physical APTS box:

Sync Monitoring Is New and Advancing
Combining functionality will provide the efficiencies needed for the advanced networks of tomorrow. The ultimate solution for synchronization delivery and assurance certainly looks likely to involve the poacher also doing gamekeeper duty.
At Oscilloquartz, we continue to advance synchronization solutions that not only deliver time accuracy, but provide simultaneous probing across the network. It’s about making monitoring easy, cost-effective and unobtrusive so the networks of today grow quickly to support the fully connected world of the future.
