When operating on a DDS network, the timing should be FROM NET-
WORK. On a point-to-point private network, one DSU III ARdc must be
set for MASTER, and the other set for FROM NETWORK. Table 5-5
shows the equivalent AT commands for setting the clock source.
Select Master timing only if the circuit has no timing source (for example, two
DSUs and a crossover cable).
