nFeature-rich Carrier Ethernet Switch for Metro Ethernet

The switch delivers advanced functionality in Carrier Ethernet switch including IEEE 1588v2, OAM, CFM, etc. It also enhanced security features such as IP source guard, Access Control List guard your network from unwanted or unauthorized access.

It helps users to build on the market-leading price/performance with Carrier Ethernet switch, and provide secure, reliable for metro Ethernet deployments.


nExceptional Precision with IEEE 1588v2 (TC, BC)

The switch performs IEEE1588v2, including transparent and boundary clock capabilities, implementations in hardware, so there is no performance penalty on packet processing.

The hardware architecture ensures low latency and high time accuracy – which is critical for delay-sensitive financial and mobile applications.


nSuperior reliability through OAM and CFM for Service Assurance

Service assurance is provided through a rich feature set of operations, administration, and maintenance (OAM) functionalities. It can simplify and facilitate the management of Carrier network, resulting in diminishing operational costs.

The Ethernet access device also offers standards-based fault and performance management in adherence with 1731 PM and 802.1ag connectivity fault management (CFM) standards. It comes with Y.1564 that include both generation and reflection of traffic.

These features contribute to significant reduction in operational expenditures and allows for troubleshooting without expensive truck rolls.


nLowing Total Cost of Ownership (TCO) with Energy-efficient Design

The switch is designed to help companies to save power needs and reduce TCO by Energy Efficient Ethernet (IEEE 802.3az). It can be used for customers to build a green Ethernet networking environment.
