What you are doing wrong is that for a T1, tip and ring are in the reverse order for the orange pair compared to a 568B cable. A T1 plug should be wired R-T-0-R-T-0-0 from pin 1 to pin 8, where "0" means not used. A 568B plug is wired T-R-T-R-T-R-T-R.
So if you wire the plug 568B, you can reverse the color scheme of the orange pair at the other end and get the same result.
