NEWPORT BEACH, Calif.--A milestone in interoperability of chip products based on the symmetric high-bit-data-rate digital subscriber line (SHDSL) standard has been reported by Conexant Systems Inc.'s Mindspeed Technologies subsidiary here and Infineon Technologies AG of Munich.
The two companies today said they have achieved SHDSL interoperability with each other's G.SHDSL products through testing in Mindspeed's laboratory.
"This is a revolutionary step for SHDSL interoperability," declared Mark Steenstra, division director of DSL strategic marketing for Mindspeed, which is Conexant's soon-to-be-spun off business aimed at Internet infrastructure applications.
"The Mindspeed and Infineon engineering teams are working together directly, with no time limitations and all the resources of their laboratories, to ensure SHDSL interoperability over all conceivable conditions and scenarios that could be encountered by their customers," Steenstra said.
In addition to Mindspeed laboratory testing, the two companies have performed additional interoperability tests at the University of New Hampshire's InterOperability Laboratory (called UNH-IOL). This lab is part of a cooperative effort called UNH-IOL SHDSL Consortium, which tests out interoperability between chip set and system equipment from different vendors.
"Working in collaboration and together under the auspices of a third-party laboratory has allowed Mindspeed and Infineon to quickly achieve compliance and compatibility," stated Christian Wolf, vice president of Infineon's communications business group and general manager of the carrier access business unit.
"The collaboration between Infineon and Mindspeed includes periodic meetings between development teams, the sharing of new firmware revisions and other techniques to sustain SHDSL interoperability over the long term, but the main goal is to help speed the adoption of the G.SHDSL technology in the marketplace," he added.
