Before even attemtping to run patterns, I'd suggest testing the extended wiring with a HST-3000 which in my opinion does the best of "qualifying" any type of a copper pair that is going to be used.
Both 2-wire and 4-wire HDSL are amongst the defaults, and you can choose just about any type of wiring that you'll ever run into. No additional modules are required for this.
With a proper module, you can also test just about any type of circuit ranging from ADSL to DS0 to T-1 to old analog stuff...
I've been using it for a while and absolutely love it. YMMV.
