The CN 5305 is based on Ciena’s fieldproven True Carrier Ethernet™technology, deployed by dozens of network operators in tens of thousands of homes and businesses. It combines the low cost and high capacity of Ethernet with the reliability, management, and service quality usually associated with SONET/SDH networking systems. The CN 5305 software architecture is based on a common service-aware operating system used in all Ciena Service Delivery Switches and Service Aggregation Switches to provide consistent system and service attributes and operational efficiency.

The CN 5305 features a state-of-the-art design that delivers the sophisticated Quality of Service (QoS) capabilities, superior Virtual LAN (VLAN) and virtual switching functions, and robust management and performance monitoring features. These functions are required to support carriergrade Layer 2 Virtual Private Networks (L2 VPNs), mission-critical data, high-speed Internet, and high-quality IPTV VoIP services.

The CN 5305 incorporates the latest innovations in Ethernet switching technology, Ethernet control plane protocols, and Carrier Ethernet Operations, Administration, and Maintenance (OAM) mechanisms. The CN 5305 utilizes highperformance programmable processors to deliver new features and functionality through simplified software upgrades with minimal disruption to customer traffic. This programmable architecture keeps capital and operating costs to a minimum while providing a flexible platform that maximizes revenue potential.
