Clock Tolerance
Deviation of slave node clock from the nominal clock rate before
synchronization; relevant for nodes making use of
synchronization and direct SYNCH BREAK detection.
Deviation of slave node clock relative to the master node clock
after synchronization; relevant for nodes making use of
synchronization; any slave node must stay within this tolerance
for all fields of a frame which follow the SYNCH FIELD.
