iTN221 is a 1.5U/15-slot, high-capacity, modular PTN platform with a dual-core architecture for both Ethernet and TDM traffic delivery.
It enables a flexible network connectivity for enterprise and mobile backhaul connections, smooth evolution from traditional to next generation services, and significant reductions of failure points resulting from wiring and cabling.
The iTN221 supports up to 2 x 1G and/or 2 x STM-1/4 uplink capacities, and provides an efficient cross-connection, integration and transportation options over a wide range of copper/fiber based legacy and IP services. The maximum system uptime and Carrier-class network availability are guaranteed by full hardware redundancy, G.8032/G.8031 Ethernet and G.8131/Wrapping-Steering MPLS-TP protection. Extensive management capabilities are provided for all aspects from equipment installation and service provisioning to real-time system operation and performance monitoring.
The iTN221 offers cost-effective solutions, complying with the CE2.0 Ethernet service models introduced by MEF, E1 and pseudowire connectivity for a lease-lined and 2G/3G/LTE mobile backhaul. In addition, the system also supports seamless connections with MPLS-TP and IPMPLS backbones, and converged fixed-mobile infrastructure by adopting SyncE and 1588v2 PTP. With this integrated system, Carriers and ISPs can save considerable amounts on CAPEX and OPEX for implementing scalable networks and value-added services in the future.
