DS-1 cable wiring

[tejas1]

I need to find the pin out on an interface cable from a G3 DS-1 card to an external CSU/DSU. I don't have any 120a CSU/DSUs so will use a Larsecom but can't find a cable to go from back of G3 to Larsecom. Can any one help?

On the 50 pin cable on the back of the switch, use the Violet/Orange and Violet/Green pairs. Violet/Orange is transmit and Violet/Green is receive.
