The Monitoring Configuration screen allows you to set MTIE and FFOFF threshold values for the GPS, PRS, INP1, and INP2 inputs. Using MTIE and FFOFF data, the TimeProvider can generate alarms based on user-specified thresholds and can disqualify an input, causing the TimeProvider to switch references or enter the Holdover mode.
The selectable mask definitions are DEFAULT, GPS-R, PRS, DS1, OCN, PRC, TYPE I, TYPE II, and USER. USER is the only selection that allows you to set the MTIE and FFOFF threshold values manually. All other masks are pre-defined and cannot be changed.
