MRV Upgrades Aggregation Switches for EFM Services

MRV Communications debuted a software update to its OptiSwitch 9000 (OS9000) carrier aggregation switching family, enabling a range of Ethernet in the First Mile (EFM) features.



The OS9000 product family, launched last year, is a carrier-class Metro Ethernet platform that aggregates Gigabit Ethernet links, provisions enhanced Ethernet/IP/MPLS services, and provides WDM transport. The new software enables aggregation of EFM-standard 802.3ah devices and auto-discovery of all 802.3ah enabled customer-premise equipment (CPE).



The new software enable the OS9000 to aggregate up to 24 Gigabit or Fast Ethernet-based CPE devices per system. These signals can be passed on to groomed GigE, 10 GigE, and WDM feeds and act as a second-mile transport vehicle to provider edge platforms, offering a flexible, scalable solution. Management capabilities including remote configuration, remote performance monitoring and threshold alarms, and remote loopback have also been added.



EFM OAM configuration and auto-discovery allows carriers to now configure or re-configure devices from their central office or from the software on the OS9000, eliminating both the cost of on site visits to the end customer and the hassles of self-installation. With link continuity from the central office to demarcation, services including security and QOS can now be passed through to the CPE. Previously these services were terminated and restarted adding to configuration time and expense.



MRV said its OS9000 can enable Metro Ethernet Forum-specified E-Line (point-to-point Ethernet Virtual Circuit) and E-LAN (multipoint-to-multipoint Ethernet Virtual Circuit) services that provide services tunneling and bandwidth profiles per application or subscriber.



When the E-LAN and E-Line functionality is combined with the OS9000's optional WDM module, the system can carry multiple intelligent private wavelength services and offer SLAs across a metropolitan or long distance network.
