Integrates bonded copper and fiber uplinks into sealed DSLAM design
Adtran has launched a sealed DSLAM 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 enhance the deployment of broadband services by leveraging the existing copper infrastructure while providing a migration path to a Fiber to the Node (FTTN) architecture.
According to Adtran, the new broadband access system provides an approach for deploying high-speed broadband services. The system 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 fiber uplink.
The company said that instead of bonding multiple T1/E1s together using ATM IMA, the Total Access 1148A-DMT uses Ethernet in the First Mile (EFM) to bond multiple ADSL2+ pairs. This enables more than 25 times the per-pair backhaul bandwidth of traditional copper-fed DSLAMs. With this offering, service providers can enable 20Mbps service offerings.
Mike Martin, director of product management at Adtran carrier networks division, said: “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.”
