NLP Residual Echo Estimated Echo Return Loss for LEC + Line:
After being enabled, the NLP has no information regarding the echo return loss of the
hybrid and the LEC. Therefore the NLP has two modes for the residual echo estimation:
A simple mode, which is used after the NLP activation and a comfort mode which is used
when the internal filters have usable values.
In the simple mode the equation for the residual echo RE is:
RE = S
Due to the equation above, ERLL
loss for the hybrid (which is exactly the worst case echo return loss between the LEC
receive input signal and the LEC transmit input signal).
For DuSLIC, the worst case echo return loss can be estimated by:
ERLL
