Description
Clock
Displays the clock sources: NE (node timing clock), BITS-1 Out (reference for equipment connected to the node’s BITS-1 Out backplane pins), BITS-2 Out (reference for equipment connected to the node’s BITS-2 Out pins).
Reference
Indicates the reference used by the NE or BITS-1 Out and BITS-2 Out clock. You can change the reference to the one to which you want to apply the timing switch.
Operation
Applies a switch to the timing reference:
 •
MANUAL—Commands the node to switch to the reference you selected if the synchronization status message (SSM) quality of the reference is not lower than the current timing reference.
 •
FORCE—Commands the node to switch to the reference you selected, regardless of the SSM quality (if the reference is valid).
 •
CLEAR—Clears any MANUAL or FORCE switches that are active on the timing reference.
Status
Indicates the timing reference status. Normal indicates normal operation. Manual indicates that a MANUAL switch is active; Force indicates that a FORCE switch is active.
Apply
Applies changes made to the Source subtab.
Reset
Cancels any Source subtab changes and returns the fields to their last-saved settings.
Help
