Hi all,

Detail (page 7):

        (b) the speech level of a telephone signal is commonly expressed
         in dBm0.  If the user is presented with:

                  Speech level = -7 dBm0

         this is not intuitively understandable, unless the user is a
         telephony expert.  If the metric definition explains that the
         typical range is -18 to -28 dBm0, a value higher than -18
         means the signal may be too high (loud) and less than -28
         means that the signal may be too low (quiet), it is much
         easier to interpret the metric.

If the typical range is -18 to -28, then I still have a problem to
interpret -7 (outside the range).   I'd also add that this is a
logarithmic scale.

Other than that, yes, I've read this and read it again, it still looks
fine.

Henk
