In my option81C systems we have the current cable configuration.

NT8D93AW comes from the J-19 SDI port to the DB25 male in the MDR2000. This seems like a special configuration situation. I would like to turn this over to our in-house electronics department and have them construct the appropriate cable to perform a CDR test but, I need a 'Y' cable. Does anyone know the actual pinout of this cable? We don't have any cash to purchase a manufactured cable we will need to make it ourselves. Any information would be helpful. I need to look at the raw CDR as well as sending the CDR to the MDR2000 buffer box. I need t compare the raw data with what the MDR is pushing out to our MAT. We are having calls being charged using the Charge Account Feature of the PBX that are phyisically impossible to be charged. It's a long story but, to make it short.... I need a Y cable to see what I can see. THANKS!!!
