I have 2 OPX / AT&T boxes that were working on 2 Merlin 820D systems. Removed Merlins and installed 2 new Partner systems. Hooked up both OPX"s and cannot make work. I was told they will work on the Partner. Does anyone know how to hardwire and program? Need to double check my work and to isolate problem,Thanks in advance for any help. The wiring is Ext from Partner to OPX Box, out to MPOE to other site MPOE into Line Port on other side Partner. Call Ext on site A to ring side B in Line Port?
