one "Frequency Synthesizer Module sine" has 4 ports (BNC), DDS output frequency from 0.000020000000 to 29.999999999999 MHz, one command ($FREQ) can do it (and save automatically); but if you want to use the pure10MHz sine port, you can connect the front SMA port (GTF module, master 10MHz), no need connect to rear side extension module since it is a slave frequency (DDS output).

FEI-Zyfer CommSync II 385 using 2 GTF module design, if the GPS signal loss, Rubidium Oscillator can keep the correct frequency for several years; if Rubidium Oscillator broken, the right GTF2 module (OCXO) will into working status, also will provide the precision timing or frequency output;

the GPS of left active GTF is Trimble Force22 receiver, antenna port is TNC, output is DC 5V;
the GPS of right standby GTF is Motorola UT+ receiver, antenna port is TNC, output is DC 5V;
