I have just received the October issue of the magazine 'Elektuur'
(Dutch edition).  It does contain the promised project. I have not
seen any other edition yet, so I can't say anything about publication
in other languages.
 
A long description would probably ruin this already overcrowded list.
I'll just tell you that there are two boards: a generic analog
interface and switching board, and a microcomputer board based on the
8052-AH-BASIC processor. Eight extensions, one 'foreign network' port.
Software written in BASIC, modifiable by hooking a terminal to the
microcontroller. Obvious weaknesses: no DTMF decoder (yet, it could
certainly be added - maybe a future project); no dial tone generator
(but busy is implemented).
