Lucent Technologies launches new VDSL product that delivers Ethernet in the first mile.Lucent Technologies (NYSE NYSE See: New York Stock Exchange :LU) has announced a new Very High-Speed Digital Subscriber Line See DSL. (communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and (VDSL See DSL. VDSL - Very high bit-rate Digital Subscriber Line ) product that enables service providers and private network operators to deliver the fastest DSL speeds yet to their business and residential customers. Based on a new Internet Protocol (IP) design, the V-16 IP DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. , supports "triple play" voice, data and video services, including "Ethernet in the First Mile Ethernet in the First Mile (EFM), also known as IEEE 802.3ah, is a collection of protocols specified in IEEE 802.3, defining the Ethernet in the Access networks, i.e. First/Last Mile. " data services, over existing copper wiring. The solution allows service providers to offer a wide-range of high-value advanced multimedia services, including video conferencing, video-on-demand, broadcast TV, streaming media, interactive gaming and super-high-speed Internet access. "The V-16 IP DSLAM is leading-edge technology that addresses the growing VDSL market everywhere, but especially in the Asia Pacific region, which accounts for the majority of near-term VDSL deployments," said Will Engler, vice president and general manager Lucent Access Networks. "The solution is also a perfect fit for metro optical networks because the V-16 IP DSLAM provides an Ethernet-over-Copper extension to deliver Ethernet services in the first mile of those networks." The product will be displayed at SUPERCOMM 2003 in Atlanta (Hall B4, Booth 23325). VDSL technology combines the cost-effectiveness of widespread copper wire infrastructure and the high speed of fiber optics to provide transmission speeds of up to 70 mbps downstream and 40 mbps upstream--up to 10 times faster than traditional Asymmetric DSL (ADSL) transmission. Lucent's V-16 IP DSLAM uses both symmetric and asymmetric transport modes to allow service providers to deliver Ethernet services to the "first mile"--the part of the communications infrastructure that connects the service provider's central office to a business or residential subscriber. The V-16 IP DSLAM features native packet architecture for simple, cost-effective provisioning and easy migration to next generation Ethernet-over-copper services and new broadband wireless LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. applications. The solution is highly dense in a small package--supporting up to 16 VDSL ports in a 1 RU sized unit. Up to 8 units can be cascaded and managed as one single network element. The V-16 IP DSLAM also offers Gigabit Ethernet, metallic and optical uplink options, an integrated ISDN/POTS splitter to seamlessly deploy VDSL over any POTS or ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. network and co-exists with ADSL technology. The V-16 IP DSLAM is available with companion Customer Premises Equipment See CPE. (CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment ) that can support both asymmetric and symmetric VDSL service. Based upon the expertise Lucent has gained by developing its Stinger DSLAM product line, the V-16 IP DSLAM has been developed to help service providers plan for the evolution to VDSL technology. Lucent's Stinger product portfolio is an ATM/IP based DSLAM, while the new V-16 IP DSLAM is an Ethernet platform designed to address the emerging need for service providers to deliver Ethernet services in the first mile. By offering both Stinger DSL Access Concentrators and the V-16IP DSLAM, Lucent covers the full breadth of DSL services from Ethernet to IP to ATM. |
