Hi every body,
panasonic Pbx (private branch exchange) is connected with master phones through 4 wire cable rather than 2 because it sends digital signals to the phone telling information like which lines are busy and which are talking to each other and also the pbx can be programmed through the master phone.
Does any one know what is the protocol and format of this communication because i want to make a microcontroller that communicates with the pbx
thanks
