New chipset for integrated line testing on xDSL access equipment from Infineon

Infineon has introduced a new chipset to provide integrated line testing on xDSL access equipment, and supports all DSL technologies (ADSL, VDSL & SHDSL) and matches the accuracy of external test heads while offering an extended feature set compared to PSTN line testing, including features like board production tests and search tone. The multichannel Metallic Line Testing (MLT) solution with built-in 'wetting current' function offers line and loop testing features for real-time monitoring of voice quality and network stability with test head accuracy and zero impact on the DSL performance.

The 'All Digital' loop approach, where the voice signal is packetized and transported as Voice over Internet Protocol (VoIP) packets in the DSL stream. Within this new digital network, there is a need to implement new methodologies to test, diagnose and locate line impairments in the loop.

"With MLT Infineon is introducing a revolutionary new line testing and loop monitoring solution for All-IP networks, which helps our customers to significantly reduce their systems costs," said Christian Wolff, President of the Wireline Communications Division at Infineon Technologies. "The MLT solution enables operators to perform 'PSTN grade' line testing within xDSL access equipment with no impact on the DSL performance."

The MLT solution consists of a 128 channel Line Test Controller (VINETIC-LTC) and a 16 channel SLIC (Smart SLIC-T16). The Smart SLIC-T16 is designed to connect up to 16 physical DSL lines and applies the wetting current to those lines, and it has no density impact on high channel count DSL linecards. The new MLT solution compliments Infineon's SELT (Single Ended Line Testing) solution for ADSL and VDSL, which provides loop information to the operator such as loop length estimation, data rate estimation, bridge tap detection and crosstalk analysis.
