RAD Exhibit EFM NTU capable of 100Mbps over VDSL2
RAD exhibited an EFM NTU which is capable of downstream speeds of 100 Mbps over VDSL2, which supports both ethernet link OAM and ethernet service OAM.
Paris, France - September 7th 2009;
At Broadband World Forum Europe 2009, which was held September 7 - 9 in Paris, RAD Data Communications exhibited an Ethernet in the First Mile (EFM) Network Termination Unit (NTU), which can reach a speed of 22.8 Mbps over 8-wires over SHDSL and 100 Mbps downstream / 50 Mbps upstream over VDSL2.
"This allows service providers to use low cost DSL or in-building copper infrastructure as the access technology, for delivering mid-band Ethernet services to customers where fiber is not present" explains Ami Barayev, Ethernet Product Line Manager at RAD Data Communications.
Owned and operated by the service provider, the LA-210 demarcation device supports Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) services, conforming to MEF-9 and MEF-14 definitions.
The LA-210 is unique in incorporating not one but two types of Ethernet operations, administration and management (OAM). Ethernet Link OAM, based on 802.3-2005 (formerly 802.3ah), which provides remote management, including remove loop-back, remote fault indication, dying gasp, and retrieval of MIB parameters. Ethernet Service OAM, based on 802.1ag and Y.1731, provides end-to-end fault monitoring and performance measurements. "Ethernet OAM is a cornerstone in the transformation of Ethernet into a carrier-class technology". Barayev states. "It enables providers to proactively monitor their service end-to-end, reducing operational expenses (OpEx) in the process."
EtherAccess Feature Set:
RAD has incorporated its EtherAccess feature set into its Ethernet demarcation units, aggregators and integrated Ethernet in the First Mile (EFM) access devices over fiber, DSL and copper circuits. These unified EtherAccess features enable seamless Ethernet access by providing same service attributes and user experience, so that Carrier Ethernet services can be ubiquitously extended to the subscriber premises, with flexible traffic management capabilities and end-to-end service level assurance regardless of the underlying access technology or the number of intermediate operator networks.
