If the 965DSP has DSL Parametric Test capability (/SA option), and the 3M FED II has been selected for the Far End Device, five additional service types are available. These are HDSL2, HDSL4, H2/4ACC, H4NACC and H4RACC.
H2/4ACC is a prequalification/acceptance test for HDSL2 or HDSL4 service. This service type selection invokes a special set of sweep frequencies as well as E, F, and G weighted wideband noise measurements. HDSL2 and HDSL4 introduce the Loop Attenuation measurement per ANSI T1.418- 2002 as well as wideband noise measurements. Loop Attenuation approximates the Pulse Attenuation metric that is measured as part of the training sequence for HDSL2/4 modems. H4RACC and H4NACC are specific prequalification/ acceptance tests for Repeatered and
Connect the red test lead to ring of the pair, the black test lead to the tip, and the green test lead to ground. If the CTC SmartStrap is being used as a far end device, also connect the yellow test lead to one conductor of the control pair and the blue test lead to the other conductor. Make certain that the far end device is connected to the pair under test at the far- end. From the Auto Menu screen, press the [enter] key to start the Autotest.
