Now my project is to design Four lines microcontroller based PBX. I have searched the forum there are lots of incomplete information. the only thing that is casing trouble for me is how to manage MT8816 in such a way that other lines aer not crossed, is there any technqiue for handling this. All intercom lines via slic ic are connected at rows x0, x1, x2 , x3. Dial tone from a oscillator is connected at Yo and i like to use the same for all sets and for engage and dial and ring back tone.
