TechnologyDescriptionValue to the Carrier
DBPR Ring ProtectionNovel method to carry best-effort data as extra traffic in existing TDM protect channelsUnlock and double available work bandwidth in existing SDH microwave rings
EoPDH Aggregation with DS0 GroomingHigh-capacity statistical aggregation of EoPDH and EoS traffic with DS0 level re-packing of E1s carrying voice trafficMaximize reuse of PDH microwave while avoiding book-ended solutions; no stacking of EoPDH/EoS cards required
ERPS Ring Protection on SDHSub-50ms protection switching in Carrier Ethernet packet rings without reserving bandwidthDouble available ring capacity for carrying high-priority 3G traffic using both sides of SDH rings
TechnologyDescriptionValue to the Carrier
3-level Hierarchical QoS with L3/L4 classificationDiscriminate data traffic at three levels – port, tunnel and service marker; granular rate shaping based on deeper inspectionSupport more monetizable flows for the same aggregate traffic and better segmentation of customers for higher profits
PBB with Carrier Ethernet OAM and ERPSCarrier-grade version of “plug-and-play” Ethernet with network and service scalabilityLaunch multicast services like Mobile TV. Offer SLA based services to Enterprises
Open Ring ERPSSub-50ms protection switching in “partial” rings or chains while subtending on L2 or IP networksLimit bandwidth upgrade costs in Aggregation and Core by realizing “open”packet rings
TechnologyDescriptionValue to the Carrier
Circuit Emulation (SAToP/MEF 8, CESoPSN)Transparent or “Structure-aware” carriage of TDM circuits on PacketsLower network complexity and operational costs by dismantling legacy TDM infrastructure
Packet Synchronization (SyncE, 1588v2)High-quality transport of a synchronization clock signal over a physical or packet layerAssure excellent QoE to voice users and reduce churn. Time-of-Day delivery for SLA monitoring
Connection-oriented L2, OAM and 1+1 Line Protection (PBB-TE, MPLS-TP, ITU G.8031)Capability to create deterministic, protected tunnels on a Carrier Ethernet network with point-and-click provisioning from a central NMSOffer advanced real-time and CBR services in LTE with stringent latency/jitter/packet loss thresholds and sub-50ms linear protection switching
