[time-nuts] Question on OSA8600 Oscillators

Hi Ulrich;

It was to adapt the BVA to a telecom system. I cannot remember the exact
 pin out. You can easily check by removing that extension. It houses a 
POT and the DB9 to DB9 crossover wiring adapter. You can then see the 
correct pinout since the internal DB9 connector on the main BVA is 
conventionally wired. Email of call if I can be of more help.

Best Wishes;
