What is the concept for Self Healing Sync?

When you deploy a Qulsar slave in eNodeB and Qulsar Edge Grandmaster (EGM, GPS referenced) in the network, then the EGM has an additional capability to use the slave as a reference if it has GPS capability. This adds to the resiliency of the sync architecture, where your reliance on GPS, followed by PTP (network sync) is supplemented by another source of sync which is the slave itself utilizing its GPS capability.
