Secondary Clock:
The secondary source of timing for the DACS module must be specified by the user, this is the timing
that will be used if the primary source of timing becomes unavailable. Note that incorrect network
timing can cause system errors and instability. The available timing options are:
Internal clock (also called “not used” by some RFL employees),
External clock, and
Timing recovered from any of the 8 T1 ports.
Note that not all combinations of primary/secondary timing sources are valid.
Note: Refer to paragraph 5.5.3.7.1.1 for T1 Timing Modes
