1. AGGREGATION Sa E mM N Time Pictra TimeProvider 500 TimeProvider 500 However backhaul networks with many hops and asymmetric paths between the grandmaster and the PIP client or networks with multiple transport 7 technologies or those with high packet delay variation due to loading or other issues cannot be sure to consistently meet the required specifications One solution is to upgrade the backhaul network for Synchronous Ethernet and include a PIP boundary clock In every 3 transport element This is the approach in ITU T G 8275 1 with full timing on path support from the network This solution requires that every network element between the grandmaster and the client support Synchronous Ethernet and include a boundary clock function a solution that is not always feasible due to the high cost to upgrade a network or because the mobile carrier employs 3rd party networks for backhaul ACCESS Figure 1 Synchronization overlay using advanced PTP boundary clocks DATA SHEET Furthermore operating at Ethernet Layer 2 G 8275 1 may obsolete or conflict with the current MPLS network design and provisioning policies of the current backhaul network 7 A better solution is to deploy an Edge Master class of product using the approach proposed in G 8275 2 Figure 1 depicts TimeProvider 2300 deployments at planned locations This deployment mitigates or elimin2. Integrated GNSS receivers are a viable alternative for timing of macro eNodeB equipment though operations would still be jeopardized by the well publicized vulnerabilities of GNSS systems and so using network distributed synchronization at least for backup is considered best practice Metro or public access small cells present new challenges for synchronization They require tight timing accuracy but are often deployed in locations where adequate GNSS Signal reception is not feasible indoors tunnels and urban canyons for example TimeProvider 2300 is designed for cost effective deployment at small cell aggregation sites From this location most small cell backhaul links can support distribution of PTP timing to small cell base stations Should the small cell backhaul links themselves include many hops or high packet delay variation PDV the problem can be solved by deploying an advanced boundary clock at selected small cell network nodes Protected Synchronization As tighter synchronization becomes more essential to the normal operation of the network Inter Cell Interference Coordination for example the negative impact of loosing synchronization becomes more significant Rubidium oscillators provide a way to protect synchronization by delivering best in of 1 5 usec for up to 24 hours Often seen as expensive upgrades for individual macro base stations rubidium oscillators in an advanced boundary clock are now mor
