Create a PBX like system with a bs2.
Hello, I am trying to create a simple type PBX..
Basically all want to do is:
hookup this box to my telephone network in my house (we will not have any service from bellsouth or whoever)
I will want to be able to ring·all the phones (exacully like the telephone company would do)from this box (maybe a push button to ring all phones), and be able to communicate with them (via a speaker/mic setup or another phone jack to hookup a phone so I can talk to the user).·
I would also like to be able to display CID info on all the phones.
I have looked around a good bit.. but have only found bits and pieces of this project.. and none for bs2 (well, I have found some stuff dealing with phone equipment like nuts&volts august 2004 edition.. pp28, but that isn't what· Iwant to do)
Do you'll have any ideas?

As I recall, this is fairly simple, but is not trivial.
IT LETS YOU HAVE A SINGLE LINE PHONE SYSTEM WITHOUT CONNECTIONS TO THE COMMERCIAL LINE. MANUFACTURER DOE NOT STATE THAT. I HAVE DONE IT HERE.
TOUCHTONE PHONES ONLY. PULSE DIAL WILL NOT WORK.
THE CM-8880 CAN BE USED TO MONITOR AND DISPLAY THE DIAL CODE WHICH IS 11, 22, 33,44,55,66,77.
EACH RING HAS A DIFFERENT SOUND AND ALL PHONES HEAR ALL RINGS SINCE THE PHONES ARE IN PARALLEL. NOTE YOU CAN HAVE MORE THAN 7 PHONES ON THE LINE BUT ONLY SEVEN DISCREET SIGNALS.

I am in college, and this is a project.. so I don't know if a product on the market would go over well.
I am just looking to make the circuit with a breadboard (maybe then get it etched), then test it out.. so I can get a better knowledge of telecoms [noparse]:)[/noparse]
thanks for the link though, that is what I had in mind
