and the telephone line 102 of the general telephone EXTm are connected in parallel and connected to the subscriber circuit LIN. Also,
Multifunction telephone MFT and multifunction telephone control device MTC
The terminals are connected by a control line 101 for information transmission, and between the multifunction telephone control device MTC and the subscriber circuit LIN, the multifunction telephone MFT's numeric dialing information (including special number function button dialing), hook information, and ringing signal control are connected. They are connected by a control line 103 for exchanging information and the like.

装置CCへ送出される。 When either the multi-function telephone MFT or the general telephone EXTm goes off-hook, a loop is created in the communication line 102, an off-hook signal is detected by the loop detection circuit, and the off-hook signal is transmitted through the AND gate 204 and the bus control circuit.
The call is detected by the central control unit CC of the exchange via the SP bus. Next, the dialing information is a regular phone.
In the case of EXTm, it is sent to the central control unit CC via the communication line 102 along the above-mentioned route. In the case of the multi-function telephone MFT, information on the numeric dial buttons is received by the multi-function telephone control device MTC through the control line 101 in FIG. 1, and this information is converted into a dial pulse train signal, 103, the AND gate 204 in the subscriber circuit LIN and the bus control circuit, and is sent to the central control unit CC of the exchange in a signal format equivalent to that of the general telephone EXTm. Also, when a function button corresponds to a special number dial, it is converted into a dial pulse train in the multifunction telephone controller MTC shown in FIG. 1 and sent to the central controller CC through the above-mentioned route.

According to the present invention, since all information is sent and received via the control line, there is no need for a dial conversion circuit or a conversion circuit for converting a ringing signal into a ringer control signal within the multifunction telephone. This has the effect of improving the economic efficiency of hardware and simplifying software.

Accordingly
It is expected that the processing power of CC will be improved and the program capacity will be reduced.
