Will a Panasonic KXT7740 DSS work with a KXTDA50 system? If so, is it compatible with a KXT7633 display set at the operator position? Any additional programming needed as well?
WTD???

YES!

Awesome! any advice to accomodate this installation procedure? i.e., programming steps, etc.....

The console needs to connect to a separate DLC port, then that port needs to be paired with the extension of the phone.

Thanx!
