DSL Parametric Tests (/SA option only)
965DSP models which include DSL Parametric Tests are identified by the /SA option on their Welcome screens. The Welcome screens for the 965DSP/SA and 965DSP/SA/ADSL are shown below.
For DSL loss and DSL noise measurements (/SA option only), you first need to select the type of DSL service that you want to test. This automatically selects the appropriate line termination impedance and noise weighting filter for the selected service. Parameters for the different services are indicated in the table below.
