Button numbering for an XM-24 module

[TheCount]

Who knows? How to program xm-24 buttons. There are 255 lines in the digital telephony section of a user.
I have connected a XM-24 to a 6416D+ station, so you would think that you can use button 17-40, but it isn't????

Thanks in advance

Sorry but i found the problem. It was a wrong power cord, so the xm-24 module did not work well.

Have you Power Unit for telephone 64xx series, eg. 1151A1? This unit give you additional 48V DC power on pin 7(-) and 8(+).
