I need to make a simple automatic phone exchange system.
Is it possible?
Can anyone tell me the web site writing about automatic phone exchange system?
Thanks,
Thomas Ritche
Possible, but the one I saw in an elecronics magazine had one side of
the incoming phone line connected to the internal ground. Now that's
not only bad for a balanced line, but it is unsafe.
Your best bet is to pick up a used system that will handle the number
of phone sets and incoming lines you need. A good used Panasonic or
similar will sell for a few hundred dollars.
Try the newsgroups comp.dcom.telecom.tech or alt.dcom.telecom.
