The Total Access 1148-DMT DSLAM is designed to enable 10-Mb/s to 20-Mb/s services by bonding up to eight copper pairs of ADSL2+ in node uplinks using Ethernet First Mile technology (also referred to by IEEE standard 802.3ah), bringing more than 100 megabits per second to neighborhood nodes within 8,000 feet and more than 75 Mb/s to those within 10,000 feet.
“This innovative solution allows service providers to defer their investment in fiber but still offer competitive bandwidth solutions up to 20 Mb/s per user,” said Teresa Mastrangelo, principal analyst at Broadband Trends, in a statement released by Adtran announcing the new product.
Similar offerings from competitors require using multiple vendors’ gear, Adtran said.
As its name implies, the 1148 DMT uses Discrete MultiTone (DMT) modulation, a technology that splits available bandwidth into subchannels and maximizing use of those subchannels.
“We’re taking advantage of the asymmetric nature of DSL users,” said Robert Conger, Adtran product manager.
