Question about Panasonic KX-T7730 Corded Phone
What's a 2:1 coupler? The modular jacks on CO lines is an RJ-14 connection. As a minimum, plug one line into CO1&2 and one line into CO3&4. Now try it again. My guess is you have doubled up the lines by the "coupler". The real wiring is that you bring in one line on the inner pair and one line on the outer pair of the jack plugged into CO 1&2.
Do you have a manual for the system or are you trying to "wing it?"
