MRV Announces New Platform for Mobile Backhaul Migration Flexibility
By Anamika Singh
MRV (News - Alert) Communications has released OptiSwitch 904-MBH, or “OS904-MBH,” a compact carrier Ethernet demarcation device with support for IEEE 1588v2 and synchronous Ethernet, offering the first wireless demarcation device with the two most popular timing mechanisms for 3G and 4G networks.
The company provides packet switching, packet optical, or “POTS,” physical layer and out-of-band networking equipment, services and optical components for high-speed carrier and enterprise networks and specialized aerospace, defense and other communications networks.
The OS904-MBH is the latest addition to the company’s OptiSwitch 900 service demarcation series. The platform functions as an Ethernet equipment clock, or “EEC,” and combines both physical layer synchronization over Ethernet, or “SyncE,” and precision time protocol, allowing migration to packet-switched wireless backhaul services without the loss of traditional time division multiplexing, or “TDM,” quality synchronization to cellular base stations. OS904-MBH becomes the first demarcation device to enable synchronization-gateway functionality between synchronous and asynchronous physical layer networks for both 3G and 4G wireless services.
The OptiSwitch 900 series is a compact carrier-class Ethernet Demarcation service unit. The OS900 enables premium manageable Ethernet services with extensive traffic management and end-to-end control for Service level conformance.
“Today’s carriers are facing growing cost and bandwidth pressures to move from E1/T1 TDM transport to packet-based transport, but the migration to next generation networks (NGN) involves significant technical challenges,” Noam Lotan CEO of MRV Communications (News - Alert), said. “With the flexibility of the OS904-MBH, operators can effectively migrate to packet-based backhaul networks to support their existing 3G networks and keep them in place when they move to 4G technologies.”
In addition to the synchronization flexibility, the OS904-MBH provides robust traffic management for enhanced quality of service. With enhanced quality of service, network operators can ensure timing packets have priority over other packets sent through the network in order to avoid dropped calls and other connectivity issues.
All timing synchronization and connectivity services can be monitored remotely via comprehensive end-to-end Ethernet OAM tools with nanosecond precision and RF2544 wire speed throughput analysis.
