  • 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
