I believe I know the answer to the question I am about to pose but I wanted to reach out to the group to seek confirmation.
Can I connect a timing cable between the RJ11 ports of a Backhaul Master and a Backhaul Slave and configure the Backhaul Master to receive its sync from its timing port? The Backhaul Slave in this particular configurtion receives its timing from its remote Backhaul Master buddy who is physically connected to a CMM.
BHM (Connected to CMM) <----------> BHS <-- TIMING CABLE --> BHM <----------> BHS
Yes, we do it all the time. The timing will not be identical to the modules receiving on GPS because the delay in the radio transmission but it will be very close.
