I just got my hands on a used AT&T/Avaya System 25. I have noticed on the main CPU card, there are two pin connectors on the front. I am trying to figure out how to build my own connector so I can attach a 9 pin d-sub rs232 connector so I can administrate the modem. Does anyone know that pinout?? tnx

Let me clarify this message.
I have a ZTN142C CPU card. There are two connectors on the front of the card. I am trying to get the pinouts for those cards or specifically the pins used for the RS-232 interface to the system administration.
