Principally, the SCLE works similarly to the SCAE. The formula of SCLE is the following:
Being in TX-mode, the speech comparator at the line side controls the switching to RX-
mode. When the SR-signal is higher than the SX-signal plus the expected/measured
echo return loss (VLE) and if SDR has detected speech, the comparator switches
immediately to RX-mode.
