The external port of a clock board can be used to connect the external time. In addition, the external port can be used for the concatenation of the clock boards within a multi-subrack NE. In this user interface, you can set whether the external ports on clock boards are used for concatenating the clock signals among the clock boards in the multiple subracks on an NE.
Background Information
NOTE: When concatenation of the external ports of a clock board is configured, the 120-ohm external clock interface cable should be used as the network cable for the concatenation.
Navigation Path
In the NE Explorer, select an NE and then choose from the Function Tree.
