When operating on a DDS network, the timing should be from the
most stable clock source, usually F
point private network, one DSU III AR must be set for M
the other set for F
commands for setting the clock source.
When the DSU III AR is set as the master clock source, it will
default to its internal oscillator as the clock reference. To enable the
External DTE port as the reference clock for the circuit, see Chapter
6, Configuring DTE Options on page 6-1.
