ADTRAN Introduces Industry's First Sealed DSLAM with >100 Mbps Backhaul over Existing Copper.New Platform Enables 20 Mbps FTTN-Based Broadband Services in Advance of Fiber Deployment HUNTSVILLE, Ala. -- ADTRAN, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on : ADTN ADTN Administrative Data Transmission Network ADTN Administrative Data Telecommunications Network ), a leading supplier of next-generation broadband solutions, today announced the industry's first sealed 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. with an integrated bonded copper uplink. The Total Access 1148A-DMT integrates both bonded copper and fiber uplinks into a sealed DSLAM design, enabling service providers to rapidly and cost-effectively accelerate the deployment of enhanced broadband services by leveraging the existing copper infrastructure--while providing a seamless migration path to a Fiber to the Node Fiber to the node (FTTN), also called fiber to the neighborhood or fiber to the cabinet (FTTCab),[1] is a telecommunication architecture based on fiber-optic cables run to a cabinet serving a neighborhood. (FTTN (Fiber To The Neighborhood or Fiber To The Node) See FTTC. ) architecture. ADTRAN's Total Access 1148A-DMT broadband access See broadband and wireless broadband. system provides an innovative approach to the successful deployment of high-speed broadband services. Leveraging ADTRAN's market leadership in Carrier Ethernet and sealed FTTN DSLAMs, the Total Access 1148A-DMT is a sealed FTTN DSLAM that provides two transport options: an integrated bonded copper uplink option capable of providing >100 Mbps or a traditional Gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. fiber uplink. Instead of bonding multiple T1/E1s together using ATM IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting , the Total Access 1148A-DMT uses 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. (EFM (Ethernet in the First Mile) Using Ethernet to provide connectivity from the customer to the carrier. See 802.3ah. ) to bond multiple ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line 2+ pairs. This enables more than 25 times the per-pair backhaul bandwidth of traditional copper-fed DSLAMs. With this solution, service providers can enable 20 Mbps service offerings that were once only practical with FTTx architectures. Consumers are continuing to demand higher bandwidth services to support various applications, from peer-to-peer file sharing Copying files from one computer to another. See peer-to-peer network, file sharing protocol and file and printer sharing. to online music and video downloads. Traditional consumer broadband is largely asymmetrical in nature, providing significantly higher bandwidth downstream than upstream. High downstream bandwidth requirements have historically driven service providers to install fiber--simply because there were no copper-based transport solutions available to match the consumer offerings. "Access to fiber is not ubiquitous and deploying new fiber is not always a viable economic solution. The ADTRAN Total Access 1148A-DMT allows service providers to maximize the use of their existing copper plant to meet the increasing demand for bandwidth," said Teresa Mastrangelo, principal analyst, Broadband Trends. "Leveraging the asymmetrical nature of ADSL2+ as a transport technology, this innovative solution allows service providers to defer their investment in fiber but still offer competitive bandwidth solutions up to 20 Mbps per user. The Total Access 1148A-DMT also has integrated Gigabit Ethernet fiber uplinks which further protects the investment and allows the service provider to transition to fiber at its own pace and without the need for additional equipment." "ADTRAN's goal is to provide an innovative approach to the needs of service providers, allowing them to address the demand for a variety of services in the most efficient and cost-effective means possible," said Mike Martin, director of product management, ADTRAN Carrier Networks Division. "While there are a limited number of other solutions available that offer bonded copper to a DSLAM, they are all two-vendor, two-platform solutions -- which greatly increase both capital cost and operational complexity. The Total Access 1148A-DMT is a single platform solution, which integrates copper transport capability into our industry-leading sealed DSLAM portfolio. This integration provides an economical, operationally friendly solution for shortening loops to deliver high-bandwidth services. This allows service providers to defer the expense of deploying fiber while remaining competitive with alternative broadband offerings." ADTRAN's market-leading Total Access 1100 Series sealed FTTN DSLAM portfolio eliminates the need for expensive cabinet enclosures, inefficient heat exchangers and costly site construction. By providing innovative line powering over the ADSL2+ copper transport pairs, service providers can also eliminate the need for power and batteries at remote nodes, greatly reducing the cost to deploy a node. This innovative design allows carriers to cost-effectively reduce loop lengths to maximize the performance of DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary , efficiently delivering fiber-like performance across existing copper transport.
