change synchronization
Each system contains a hierarchy of sources used for timing synchronization.
DS1 inputs to the external stratum 3 clock affect stratum 3 synchronization
hierarchy. Primary and secondary fields reflect Stratum 4 synchronization. If all
fields are blank, the tone clock board within each PN provides timing for that PN.
Output
The following example shows the output for the change synchronization
command. “4” was entered in the stratum field.
The following output example shows the output for the change synchronization
command. “3” was entered in the stratum field.
