What happens if you don't enable Sync-to-Channel and you have collocated Servers? You have good odds that you
will see a decrease in throughput due to the systems trying to occupy the same frequency at the same time. In severe
cases, you could lose communications all together depending on how much bandwidth your system requires. Due to
crystal differences between the Servers, you could see the interference come and go.
