Carrier Ethernet Switch

Model HA-821
Series Optical Transport System
Product Description


Affordable and Seamless 1G/10G Carrier Grade Ethernet Aggregation for Ethernet WAN and Wireless Mobile Backhaul 
The HFR HA-821 is a cost effective, multiservice, carrier-grade, rack-mountable (ETSI 300 mm) device designed to deliver Carrier Ethernet services in support of enterprise business and wireless mobile backhaul service applications. The HA-821 can be installed as a 1G aggregation node in a Carrier network, providing layer 2 backhaul in 10G Ethernet Metro core rings.
With its small form factor and low power design, the HA-821 can be installed in customer premises to address space and power challenges, deliver high performance and scalable services, and reduce operational costs
Standards-Based Multiservice Delivery
Designed to support Metro Ethernet Forum (MEF) specifications, the HA-821
delivers Ethernet Private Line, Ethernet Virtual Private Line , Ethernet LAN,
Ethernet Access, and Ethernet Tree connectivity in linear ring topologies  

for high capacity business and mobile backhaul 4G services. 
Service Level Provisioning, Monitoring and Management
Graphical user interfaces based upon SNMP are available to provide users a full solutions management view: the individual node; the end-to-end network; and the deployed services. With dedicated hardware for traffic performance
monitoring, the HA-821 delivers on today’s requirement for hardware based
Y.1731 latency, delay variation, and frame loss ratio measurements. Tiered  

Ethernet services as well as wireless backhaul service level performance may
also be monitored through the web-based SLA portal. 


Key Features

The HA-821 provides aggregation for Carrier Ethernet services for Network Operators in dense urban areas. Supporting business services and backhaul of radio access networks (RANs), the HA-821 implements G.8032V2 Ethernet Ring Protection, performs Ethernet services demarcation, and provides class-of-service support, traffic management, prioritization, synchronization, and service inter-working with 64 Gbps of switching capability.
