This is the f3-platform counterpart to esaProbeCOSConfigSoamPmExtFlrDeltaTNumLmPdus: a read-write Unsigned32, ranging 1 to 1000000, setting the number of loss-measurement PDUs that make up one delta_t on f3-series cards, per its description. An administrator uses the same worked example the description gives: with a 100ms SLM message period and this set to 10, delta_t comes out to 1 second, letting them size availability windows consistently on f3 hardware. For example, an operator matching delta_t behavior across card types would set this f3 object to the same value of 10 used on the Esa version elsewhere in the chassis.
