I'm working with a GE repeater, Master II. Its tone remoted. It is setup and working, but I'd like to know how to set the tone remote levels correctly over the phone line. It uses a dedicated copper telco line.
I know the audio voice levels should be set at 0db. The high level gaurd tone should be preset to +10db over that, and the low level gaurd tone will be preset to go out at -20db. Given a 16db allowable loss on the phone line, the low level gaurd tone could be at -36db at the repeater. Is that correct? Will it run that that level? How can you accuratly measure it? Everything is working, I'm just wondering about this for discussion purposes.
