Re: [Asterisk-Users] Ztmonitor values when zap channel is onhook

With txgain set to 0.0, people on the other end complained about low volume from our side hence I started out with a positive value. Are the ztmonitor Rx: values of around 90 - 400 normal even when the zap channel is Onhook or do I have some problem on the pots lines that I should fix?

Re: [Asterisk-Users] Ztmonitor values when zap channel is onhook
We just replaced our old system at work with Asterisk. We use a TDM card with 3 FXO ports. In tuning my gains, I discovered that the on-hook rx levels do in fact waver a little bit. Line 1 is right around 145, Line 2 is around 235, Line 3 is around 380, and Line 4, which doesn't go to a POTS line but instead to a PhoneLabs Cell Socket thingy, is around 100. These numbers sometimes spike upwards by 30% or so, but not too often. So after feeling quite happy about the rx and txgain levels set at my workplace, I did the same steps at home, but in the process noted that my on-hook levels are closer to 3500. They waver a bit, but not more than 30% it seems. This is on a X100P, which I've always suspected was sold to me mis-labeled (I think it's a clone instead of a real X100P). Also, I have a DAML (sometimes also called a concentrator?) installed outside my house, to split the copper lines coming to my house with neighbors. ( I live in a trailer court and personal copper pairs are at a premium I guess. Had to switch away from 56k so long ago 'cause it wasn't 56k anymore...) but anyway the point is that the DAML might be causing the rx noise if it isn't my X10(0|1)P. By way of summary, I feel based on my own experience that the numbers you are seeing while on-hook must be perfectly acceptable and well within normal, usable limits. I think I'll order a real X100P or maybe a tdm with one FXO port to replace my junk and post back to the list with my results.
