Hello :)
For example, once I have the rxgain calibrated for all of the lines,
could I then call into, say, Zap/3 from Zap/4 and run Milliwatt() on
Zap/3 and use ztmonitor on Zap/4 to calibrate it? I'm sure it's not
perfect, but would it be close enough?
That's exactly what you do. Once I had adjusted my rxgains to calibrate
them to the signal that the phoneco gave me, I just dialed out of one
line and into another. Everything's supposedly digital on the phoneco
side, so no loss should occur. (because with the rxgains you've already
compensated for what will happen on the inbound trip through the
copper). So by then adjusting your txgains on each channel, you can
feel confident that the phoneco is accurately representing to you how
you sound from its point of view.
A second question: doesn't it seem wrong that my rxgain and txgain are
so far off when I'm just talking to a channel bank 12 feet away? I sure
don't have cable loss. It sure seems like the impedance is way off or
something. Is there a way to test this further, rather than just
cranking up the gain? My guess is that using the milliwatt line will
just tell me to make the rxgain higher, which will probably just make
the echo issues worse...
It does seem like something else is wrong. You shouldn't require such
high rxgains in my opinion, but I have no idea what could be causing
this need.
