Hello,
I need to convert the dahdi_monitor output to dBm0, so I can measure Echo
Return Loss in dB.
I've read a formula that calculate S(k) in ITU-T G.168 recommendation, where
S(k) is the signal level in dBm0. Can I use this formula to convert it? If
yes, what value should I use to the number of samples if I want to convert a
single output from dahdi_monitor?

Thanks in advance,
Gustavo Santos.
