Hi Y'all
 
Sick of drop out's , caused by them damn Telecom Touchfones????
 
Then here's the answer....
 
excuse the crappy drawing but i hope you will get the Idea...
 
Parts needed are....                      $COST  Rod Irving's
                                                 Catalog No.

1X C106D Silicon Controlled Rectifier     $1.50  T21206    
1X WO4 Bridge Rectifier                   $0.80  Z11032
1X 0.1uF Mains rated Capacitor            $1.75  R16120
1X 18 Volt Zenner Diode                   $0.30  Z10238
1X 100 K ohm resistor                     $0.05  R10070
1X 4.7 K ohm resistor                     $0.05  R10054 
 
                                        

build the circuit as per the diagram... and all is well.

apart from the benefit of not needing to unplug all the phones in the house
each time you want to use the modem, another feature is that people who
pickup a phone in the house while the modem is Online will not cause
crud on the line as they are switched automatically out of circuit by the 
modem comming online.
 

P.S. make sure connections to telecom plugs and sockets are on pins 2&6
     as telecom plugs are a 6 pin plug but only 2 & 6 are used in a domestic
     situation.



Apart from that... any problems , you're on ya own!!!
