cdmaTimeFigureOfMerit
Module: TEMPUSLXUNISON-MIB
OID (symbolic): TEMPUSLXUNISON-MIB::cdmaTimeFigureOfMerit
OID (numeric): 1.3.6.1.4.1.13827.5.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The Time Figure of Merit (TFOM) value ranges from 6 to 9 and indicates the current estimate of the worst case time error. It is a logarithmic scale, with each increment indicating a tenfold increase in the worst case time error boundaries. The scale is referenced to a worst case time error of 100 picoseconds, equivalent to a TFOM of zero. During normal locked operation the TFOM is 6 and implies a worst case time error of 100 microseconds.
During periods of signal loss, the CDMA sub-system will compute an extrapolated worst case time error. One hour after the worst case time error has reached the value equivalent to a TFOM of 9, the NTP server will cease to send stratum 1 reply packets and an Alarm LED will be energized.
What is cdmaTimeFigureOfMerit?
The CDMA sub-system's own Time Figure of Merit on the same 6-9 logarithmic scale as cntpTimeFigureOfMerit; a value of 6 is normal locked operation, while lingering at 9 for an hour signals the server will drop out of stratum 1.
