What is the operating line voltage for MM711 & MM716 modules FW 99?
 
Analog lines are -48 VDC. When testing you will see a typical voltage of around 42-45 VDC. Ring voltage is around 100 VAC. Everything depends on cable distance and quality so further away the voltages will drop a little.

I hope that helps.
 
Depending what will be on the other end will determine if you have enough voltage. When trying to use an Avaya Universal Paging adapter you will need to install a Viking ring generator in between so that it will get the 48 volts required to trip it. I went thru this problem last year.
