NLP Residual Echo Minimum Echo Return Loss for LEC + Line:
The RE-MIN-ERLL coefficients defines, when the NLP should switch from the simple
mode to the comfort mode. If the estimated echo return loss for the hybrid plus the echo
return loss for the LEC is higher than ERLL
In comfort mode, the NLP estimates the residual echo by itself.
RE-MIN-ERLL = (2/(5
ERLL
(see
The echo return loss is the difference between the signal level in receive direction S
the echo level in transmit direction S
