An instrument for real-time emulation of DSL binders [digital subscriber lines]

This paper presents an instrument for real-time emulation of digital subscriber loop binders. The instrument is based on the accurate description of the transmission channels characteristics and the binder´s crosstalk environment. A key feature of the presented instrument is its ability to support single and multiple lines. In the multiple lines configuration, the pair-to-pair crosstalk injection is based on the actual data transmitted over the disturber lines and is achieved using analytical emulation of the pair-to-pair crosstalk coupling effects.
