I have had my linesman go over the lines on the pole and manhole and
remake the connections, I have played with the milliwatt generator to
dial out and back to another number, measuring with ztmonitor to
establish the levels, and I have played with the echo canceller
settings. I still get hum and crappy audio with lots of echo. When I
listen to the lines with a butt set they sound clear, no hum.
Has any successfully used an Adtran 750 with PSTN lines? I have several
and changing the unit or cards does not improve the quality.
