ADTRAN Launches Total Access 1148A-DMT

ADTRAN (News - Alert), Inc., a supplier of next-generation broadband systems, has reportedly launched Total Access 1148A-DMT - its first sealed Digital Subscriber Line Access Multiplexer, or “DSLAM,” featuring integrated bonded copper uplink.
 
Integrating both bonded copper and fiber uplinks into a sealed DSLAM design, this new system is capable of allowing service providers to rapidly and cost-effectively accelerate the deployment of enhanced broadband services by leveraging the existing copper infrastructure, while providing a smooth migration path to a Fiber to the Node, or “FTTN,” architecture.
 
ADTRAN's Total Access 1148A-DMT (News - Alert) broadband access system is said to offer two transport options: an integrated bonded copper uplink option capable of providing >100 Mbps or a traditional Gigabit Ethernet fiber uplink.
 
Instead of bonding multiple T1/E1s together using ATM IMA, the Total Access 1148A-DMT uses Ethernet in the First Mile, or “EFM,” to bond multiple ADSL2+ pairs. This enables more than 25 times the per-pair backhaul bandwidth of traditional copper-fed DSLAMs. With this system, service providers can enable 20 Mbps service offerings that were once only practical with FTTx architectures.
 
The increase in the demand for higher bandwidth services that can support various applications, from peer-to-peer file sharing to online music and video downloads, have reportedly driven service providers to install fiber, because there were no copper-based transport systems available to match the consumer offerings.
 
Mike Martin, director of product management, ADTRAN Carrier Networks Division, said that the company’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.
 
“While there are a limited number of other systems available that offer bonded copper to a DSLAM, they are all two-vendor, two-platform systems — which greatly increase both capital cost and operational complexity,” Martin said. “The Total Access 1148A-DMT is a single platform solution, which integrates copper transport capability into our industry-leading sealed DSLAM portfolio.”
 
Martin also said that 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,” he added.
 
ADTRAN's new system is said to eliminate the need for expensive cabinet enclosures, inefficient heat exchangers and costly site construction. And, its innovative design allows carriers to cost-effectively reduce loop lengths to maximize the performance of DSL, efficiently delivering fiber-like performance across existing copper transport.
