I've pulled it apart and the board does show a connection to the EXT C-FIELD. That trace runs to a jumper labeled A C B and currently C B is shunted. Any particular Motorola oncore model required - I see a bunch of them on Ebay...

Von Samsung Mobile gesendet Rex <r...@sonic.net> hat geschrieben: I don't think the rubidium module for these systems can be disciplined. I think they were only intended as a backup if the XO section or GPS failed. The XO section does discipline but I don't know the details. I'm not sure of the model number, Lucent had several variations on the same theme in that time frame. I had one of the rubidiums that may be the same as yours. Trying to trace out some of the circuits, I found that the EFC on the LPRO connector was not being used at all.
