The iTN221 is a “Pizza Box” 1.5U (full ETSI) sized, next generation multiservice access node. It offers a dual core architecture for both packet and SDH/TDM transmission. The iTN221 supports up to 2 x 1G and/ or 2 x STM-1/4 uplink capacities, and a built-in PDH multiplexer function, DXC non-blocking clock cross connect matrix at 64K level and TDM pseudo-wire functionality for TDM to Ethernet/IP/MPLS service migration. The iTN221 supports three service slots suitable for various sub cards: Voice (FXS/FXO/E&M), Ethernet (GE/FE), C37.94, 64K codirectional, Data RS232/RS485 etc. It provides utilities and transportation companies with reliable connectivity for controlling signals, mission critical data, voice, video monitoring and electrical protection services. It supports the smooth transition from PDH, SDH to the packet transmission network. For mission critical services, the system maximizes uptime and provides carrier-class network availability using G.8032/G.8031 Ethernet and G.8131/Wrapping-Steering MPLS-TP protection that provide sub-50msec recovery as well as hot swappable redundant power supplies. 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 a cost-effective solutions for providing MEF-compliant CE2.0 Ethernet services, as well as E1 and pseudowire connectivity for lease-lined and 2G/3G/LTE mobile backhaul with integrated SyncE and 1588v2 PTP.
