I did a bit of poking around for you, and I've found the numbers of the 
N-diagrams that seem to apply. 

N886 is the diagram for the wired-in version, N8886 is for the plug-in 
(both for DTMF models).

You can get said diagrams from 
http://www.samhallas.co.uk/repository/n_diagrams/

As expected, while you get an overall schematics of the phone, there are 
no internal schematics for the dialer (keypad/DTMF econder) or ringer. 
May be some help, though.
