Just wire the distant jack at the router as 568B and connect the white/blue of your cable to the red/green terminals. Connect the white/orange to black/yellow pairs as shown in the above pic. As long as the cable run is under 100 feet or so, there will be no issues.

I'm a T1 newbie, about to wire up from my new NIS (same as above) to a T1 DSU/CSU. Based on the pinout of a 586b plug on the router end, I would have wired in the NIS as:
Yellow (CT1) --> Orange (pin2)
Black (CR1) --> Orange/White (pin1)
Red (CT) --> Blue (pin4)
Green (CR) --> Blue/White (pin5)

The picture and Ed's comment seem to have the pair colors reversed, pin1 as CT1, etc. Where am I going wrong?
