Telephone plug system

A telephone line plug system comprising:

• A jack body having one end adapted to be inserted into standard telephone wall jacks, said jack body having at least one receiving socket at another end adapted to receive a conventional plug which is attached to a telephone line operated device, said plug being controlled via signaling over a provided two wire telephone line;
• a first central processor unit for controlling said signaling;
• a first modulator/demodulator for modulating every signal with a chosen frequency for a line in question, wherein said first central processor unit determines which carrier wave to use;
• a line sensor for differentiating between an idle state and an active state of the telephone line, and for detecting a ring signal;
• a communication channel for forming a communication channel to a slave plug;
• a tone generator for generating tones connected to an outgoing telephone line;
• a first buzzer for signaling,
• an identification means for providing a plug its identity in a plug system;
• a power status controlling means;
• a ring signal generating means connected to a line with a connected telephone device in an idle state;
• a DTMF decoder for decoding DTMF tones transmitted from connected telephone devices;
• and
• a power supply for generating voltage corresponding to a conventional telephone line voltage
• wherein a slave plug is provided for multiple incoming telephone lines in a plug system controlled via signaling over a provided two wire telephone line.
