You need 2-pair (XDP off) for the 7130 to work. If you want FULL functionality of the 7130 (whisper paging), you will need 3-pairs.

Hi (again!) all, and apologies in advance for my low-level questions. I have an existing KX-TD816 PBX operating in the UK with eight extensions. The handsets are (master) KX-T7433 and the rest are KX-T7420 (some seem to be KX-T7420E's if that makes a difference). I've foolishly sourced an additional handset - and as I wanted a display, I've found a KX-T7130E. However - when it's swapped out for one of the existing handsets, although the display lights with the date&time, it cannot place or receive a call. The handset sounds as though there's an open line. Now the manual states that there's a mandatory four pin wiring required for the 7130E - A,B,L,H (?) which although I can't reference it to the particular pin-outs in use, I can confirm that the existing handsets are all connected back to the PBX using four pin wiring. Therefore - do you have any suggestions (apart from RTFM!) for how I can progress this? My main issue right now is that I can't verify that the four-pin wiring used throughout is a correct four-pin wiring, and isn't simply the one-pair wiring (L,H) with the other pair wired incorrectly... as if that was the case, the 7420 & 7433 would still operate - but the new 7130 would not. Any constructive suggestions would be much appreciated!
