I bought five Panasonic KX-T7730X phones. The business i work for has a Panasonic KX-TD1232 system. I unpack all phones and tried it on different extensions and won't work. there isn't ant pulse. when i dial the extension that the KX-T7730X is on I get a busy tone. how do i configure this phone to work with my system? keep in mind that this phone does not allow me to access the programing....on all the five phones i bought. I i hear is shhhhhhh noise when i pick up the handset.

A TD system is a DIGITAL phone system and the 7730 phones are ANALOG. I don't know what X means, but I guess they're not from the US :-). Anyway, the ANALOG phones need 4 wires to work, instead of the 2 that the digital phones have. If your installer was lazy and didn't cross-connect 4 wires at the frame or put in 4 bridge clips on each jumper, then you don't have a voice path. Or, XDP is turned on and you'll have a bit of a problem.

If you have an IM and a PM for the TD system, you can find the wiring diagram and the instructions to read the XDP status. Quick answer is the first 2 of every 3 pairs will run to your phone. If you start with a digital phone in the port first, turn on XDP and plug a single line set into the XDP port, you will get dial tone (may have to dial 390 or 391 to enable/disable the XDP twinning) and that dial done will be different from the digital phone. If you don't get dial tone, your first pair wiring is missing. Fix that, turn off XDP and you 77xx series phone will now work in the port.
