Description
A hierarchy of sources exists within each system that are used for timing
synchronization. For stratum 3 synchronization, this hierarchy is reflected by the
DS1 inputs to the external stratum 3 clock. For stratum 4 synchronization, this
hierarchy is reflected in the primary and secondary fields. If all fields are blank,
then the tone clock board within each PN provides timing for that PN.
Defaults
None.
Parameters
None.
