• Dense adaptation of multiple converged services onto an economical packet infrastructure. • Extends service routing IP/MPLS capabilities to the cell site, hubs and network edge in a compact form factor. • Dynamic tunnel signaling for scaling, ease of establishment and resiliency. Benefits • Transition from PDH-based connectivity to Ethernet-based can greatly reduce recurring operating expenditures such as line lease costs. • Advanced resiliency features lead to improved network uptime, which can positively impact customer retention and allow critical services to be offered for increased revenue. • Rapid fault detection and powerful commissioning and troubleshooting tools can improve productivity of operations staff and reduce network downtime. • Multiprotocol and convergence capabilities (with flexible and granular QoS) reduce equipment instances needed to carry multiple fixed and mobile traffic streams. • Modular, flexible architecture alleviates the burden of complex pre-engineering and future scenario planning.
