MRV is a networking company with a full line of packet-optical transport (POTS), carrier Ethernet, 40G networking and out-of-band networking products.
The OS904-MBH is the latest addition to the company's OptiSwitch 900 service demarcation series. The platform functions as an Ethernet equipment clock (EEC) and combines both physical layer synchronization over Ethernet (SyncE) and precision time protocol (PTP - IEEE1588v2), allowing migration to packet-switched wireless backhaul services without the loss of traditional time division multiplexing (TDM)-quality synchronization to cellular base stations. By integrating both technologies, the 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.
"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," said Noam Lotan, CEO of MRV Communications. "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 traffic management for enhanced quality of service (QoS). With enhanced QoS, 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 Ethernet OAM tools according to IEEE802.1ag CFM, ITU-T Y.1731 PM with nanosecond precision and RF2544 wire speed throughput analysis.
The platform is compliant with mobile backhaul specifications including the MEF-22 implementation agreement and MPLS forum framework 20.0.0.
