3.6.2 Master/Master
This application is used where both earth stations have high stability clocks available,
and the received data is to be clocked onto the local network.
The disadvantage of the master/master application is that the receive data will slip, as the
clocks will not be synchronized. By using very high stability clocks, the expected time
between slips can be many days.
The buffer clock will normally automatically revert to the low stability internal reference.
