Silicon Developers Test ADSL2 Interoperability

The DSL Forum completed its second multi-vendor ADSL2 “plugfest” interoperability event conducted at the end of June in conjunction with the University of New Hampshire’s InterOperability Laboratory (UNH-IOL) in Durham, NH. Ten ADSL2 chipset developers performed three basic physical layer tests, defined in the DSL Forum’s internal “Proposed Draft 013 – Interoperability Test Plan for ADSL2 Plugfests” (PD-013). ADSL2 (also known as ITU Recommendation G.992.3) provides numerous improvements over existing ADSL standards including line diagnostics, power management, power cutback, reduced framing and online configuration. ADSL2 expands the bandwidth to approximately 2 MHz and increases achievable data rates to more than 20 Mbps. The ten silicon companies participating in the event were Analog Devices, Aware, Broadcom, Catena Networks, Centillium Communications, Infineon Technologies, GlobespanVirata, Realtek Semiconductor, Samsung Electronics and Texas Instruments. A third plugfest for ADSL2 chipsets is scheduled for the week of August 4, 2003, followed by a plugfest open to all ADSL2 system vendors — DSLAM, CPE, testing equipment, and chipset developers are all expected to participate — to test extensions to the ADSL2, including ADSL2plus and the Reach Extended ADSL2 standard the week of August 11, 2003, both at the UNH-IOL. Registration information is online.
