GlobespanVirata DSL reference design cuts board size, port costs

GlobespanVirata Inc. has released a next-generation Multiple Dwelling Unit/Multiple Tenant Unit (MxU) reference design that is aimed at reducing the board size and per-port costs of DSL equipment.

The 48-port MxU reference design is based on the company's Titanium G24 chipset and Columbia communications processor, and comes complete with the traffic and high-level network management features required for mass deployment.

The Titanium G24 chipset is claimed by the company to be the world's first 24-channel ADSL chipset aimed at next-generation DSLAM, Mini DSLAM and DLC designs.

The Columbia communications processor is a highly-integrated and programmable SoC that targets next-generation DSLAM and DLC line cards. It combines traffic aggregation, management, and Layer 2/3 Data and Control Plane functions into a single chip solution.

The processor is also capable of supporting ADSL, G.SHDSL and VDSL bit rates for line card designs from 16 to 96 ports.
