"The RB" is a little too vague in this case. I picked up one of the
RFG-RB units and I can't see anyway that there is disciplining in it. I
think it just free runs and was used as a backup if the XO in the XO
unit lost sync from GPS.
From what I have read here, the -m- units may be different and actually
do some kind of disciplining of the RB unit. IOW, the different models
of Lucent stuff seem (from messages here) to be quite a bit different.
The actual LPRO Rb that is in my RFG-RB should be possible to be
disciplined with some other circuity, but as far as I can see, not the
circuitry that is in the box.
I think I got a decent deal for what I paid, but I'll probably remove
the LPRO and not use the board that came in the box.
