Have an Option 11 with a new TMDI card with a cable ( part number NTBK04AA) coming out from the amphenol connector. I need to know what the pinout is to convert the db15 end to a rj45 bisquit jack. That will then be plugged into the csu/dsu.

I currently have pair 1 and 9 from the old db15 connector terminated on the green and red pairs on the bisquit jack. Then the 3 and 11 pairs of the db15 terminated to the blue and orange pairs on the bisquit jack. Does that sound correct.

Any help would be appreciated.

Thanks
 
You have the pin assignments correct but you may have to flip transmit and receive if it doesn't float . It should either be:

1 and 9 ----> 4 and 5 (green and red)
3 and 11 ----> 1 and 2 (blue and orange

or

1 and 9 ----> 1 and 2 (blue and orange)
3 and 11 ----> 4 and 5 (green and red)
