Metro Ethernet Switching


  • 4 x 10GE + 4 x 2.5/1GE

MEF compatible Ethernet switch

The ES-1440 family leverages the purpose-built silicon technologies to fulfill the needs that modern Carrier Class Ethernet services require with ultra-low power consumption.  The standard compliant features bring hassle free operations with the benefits of unmatched resiliency, superb synchronization accuracy, and comprehensive OAM.


Comprehensive Ethernet OAM Suite

As the SLA (Service Level Agreement) is at the center part of the Carrier Ethernet services, and the Ethernet OAM protocol suite is the key to enable the services. The ES-1440 NIDs embed the hardware Ethernet OAM engines for ensuring the real time monitoring can be achieved. The protocol suite covers link status, service level, network monitoring, as well as performance metrics.  IEEE 802.1ag CFM, 802.3ah EFM, ITU-T Y.1731 Performance Monitoring are all included in the OAM feature suite, furthermore, both IETF RFC 2544 and ITU-T Y.1564 hardware-based tester are also in place which enables the operation center the ability of performing diagnostics and performance testing remotely. This capability effectively reduces service personnel costs and ensures outstanding user experiences.

Nano-Second Grade Accurate Timing Performance

The PTP (IEEE 1588v2) has become the de facto synchronization solution that has been widely adopted in different application scenarios which requires precision timing mechanism. By incorporating the OCXO better than what Stratum 3 required, the ES-1440 NIDs perfectly maintain the 1588v2 accuracy within nano-second scale. The Sync-E (ITU-T G.826x) assisted 1588v2 delivers not only the accuracy, but with outstanding stability persistently. The importance of synchronization grows drastically as the mobile traffic grows with unprecedented speed. The exceptional PTP performance on ES-1440 effectively satisfies such synchronization requirements the LTE & LTE-Adv. base-stations needed. The 1588v2 capabilities delivered by ES-1440 ensure what LTE & LTE-A requested, and potentially what the 5G technology will need can be perfectly fulfilled.
