January 26, 2001, 1:04 PM — Nortel Networks Corp. this week extended its DSL Access Multiplexer line downward with a product targeted at remote service areas.
The Universal Edge IMAS XpressDSL platform is intended to bring broadband access to rural communities, suburban residential areas and businesses in new industrial developments. The product is designed for areas requiring fewer than 128 DSL lines.
The device is an ATM switch that offers traffic management and quality-of-service capabilities, Nortel says. A single shelf contains a 622M bit/sec ATM switch with DS-1 Inverse Multiplexing over ATM IMA, DS-3 User-Network Interface or OC-3 UNI WAN interfaces.
Each shelf can house up to 40 lines of asymmetric DSL Full/G.Lite, or 64 lines of G.Lite or symmetric DSL. Eight shelves can be connected into a 5G bit/sec ATM switch.
The switch is currently under trial with Golden West Cos., a South Dakota service provider. It is expected to be generally available later this quarter.
The Universal Edge IMAS XpressDSL chassis has a list price of $3,000. System and line card modules are additional, and vary in list price depending on port density and DSL service.
Nortel recently announced support for the G.shdsl standard and the DS-1 interface. Other members of the company's DSL portfolio include the Universal Edge Intelligent Multi-service Access Switch for high-density DSL termination and ATM switching, and the Universal Edge 9000 for integrated voice and data services.
