Our 4 wire cable runs into the roof into another apartment, but I can see the buildings cabling run into one of these telecom points (I stole this photo from Yabanize's post so you can see what ours looks like) - our one is butted up against our apartment and its cables run from ground, connect to the apartments lines which run into a hole in the wall) so I figure this is probably what I should consider my ETP.

Replacing our 4 wire cable is going to be a huge hassle because it runs into the roof and into another apartment, because it's a rental I also don't want to mess with replacing it - I was just hoping to connect a Cat5e cable from this Telecom box around the outside of the apartment into our aerial cable hole which is a great location (which is all private and fenced off from public and other apartment users), then connect that to our VDSL master filter. This means it doesn't involve messing with the existing cabling, and means I can easily return it to original when we vacate
Problem is that I will need to find what pair belongs to our apartment, will this work? http://www.trademe.co.nz/computers/other/auction-930355275.htm
Will doing this get me in trouble with Chorus? I'll use jelly clips for connecting the wires, but I do plan to run our cat5 cable around the outside of the apartment for about 10m.
