This object specifies the number of consecutive synthetic loss measurement frames to use in order to calculate the frame loss ratio. This object is only valid for lmSLM LM measurements. It is ignored for lmLMM, and lmCcm measurement types. When data frame loss is being measured using LMM or CCM the FLR can be calculated for each measurement. However, when synthetic frame loss is being measured, using SLM, each measurement yields only a boolean result, i.e. the frame was either lost, or it was not lost. In this case, a number of measurements need to be made before a sensible FLR can be calculated. This object specifies that number. The FLR is calculated after the specified number of measurement frames have been sent, and sufficient time has passed after the last frame was sent to allow for them, or the corresponding replies, to have been received. Successive FLR calculations are performed for successive blocks of measurement frames, for example if this object is set to 10, then sending 50 frames results in 5 FLR calculations: the first for frames 0 - 9, the next for frames 10 - 19, etc.
