Nortel adds to IMAS line to expand DSL coverage

Nortel Networks Corp. this week announced two additions to its broadband-access product line designed to enable service providers to address new and underserved DSL markets.

The new Universal Edge IMAS Remote and enhancements to the Universal Edge IMAS XpressDSL expand DSL networks into office buildings, apartments, hotels and city blocks.

IMAS Remote is a switch that will allow service providers to deploy DSL beyond the central office to the in-building market, as well as to outside, plant environments. It is designed for deployment in multitenant environments, remote terminals or small, central offices with lower, line size requirements or other remote deployment conditions.

The Universal Edge IMAS XpressDSL switch will allow service providers to deploy DSL in high-density locations such as multitenant units and multidwelling units.

Citing data from The Yankee Group Inc., Nortel says the home office and small-business market is underserved, with 118,000 buildings in the US that are shared, tenant office spaces, home to more than 2.3-million business tenants. Nortel's new and enhanced offerings are intended to allow service providers to capitalize on this market.

IMAS Remote supports from 24 to 96 asymmetric DSL (ADSL), G.Lite or G.SHDSL ports and up to 1,024 ATM virtual circuits. Trunk speeds range from T-1/E-1 to OC-3/STM-1.

IMAS XpressDSL fits into a 19-inch or 23-inch bay. It supports 40 ADSL ports, and 64 G.Lite or SDSL ports, and 128 ATM virtual circuits per port. Trunk interfaces include DS-1, DS-3 and OC-3.

IMAS Remote and the enhancements to IMAS XpressDSL will be available in the second quarter. Nortel did not disclose pricing.
