I have a junk Meridian M2616 business phone that I'm playing with for LCD experimentation purposes. I'd like to power the entire phone system off-line (out of the system) so that I can use the LCD, but I don't know what voltages are necessary to power the system, or if something more than power is required (communication start string for example). I know that the Meridian 1 PBX system is propriartary, so that detailed information is not available. I just want to know if there exist an offline test module or a way to power the system for such a purpose.
