Value	Field	Description
NE Name	-	Displays the NE name.
Clock Source	For example: Internal Clock Source	The clock sources in the list used by the current NE have different priorities according to their sequences, with the uppermost clock source having the highest priority.
External Clock Source Mode	2 MHz, 2 Mbit/s	Selects the external clock source mode. Only the input external clock source can be set.
Synchronous Status Byte	SA4, SA5, SA6, SA7, SA8	Selects the byte in the external clock signal used to transmit the synchronization status message. Only the external clock source input in 2 Mbit/s mode can be set.
TU		The tributary board that can be selected when setting the tributary clock source.
Clock Source Priority(Highest: 1)	An integer greater than or equal to 1	"1" indicates the highest priority of the clock source. The priority increases as the value decreases.
Use the clock source of the data port	Yes, No	Yes means use clock source of the data board, No means use clock source of the SCC board.
