Claims

[Scope of utility model registration request]

When the originating subscriber calls the terminating subscriber via the exchange,
The telephone of the called subscriber has a function of receiving a calling signal from the exchange, and the calling subscriber can monitor the calling status of the called subscriber on the exchange by tone, etc., and also whether the calling subscriber is calling the called subscriber. If the calling subscriber's telephone goes on-hook while the calling subscriber's telephone goes on-hook, the switch has a function that stops the ringing signal sent from the exchange to the called subscriber's telephone, and the calling signal is sent to the called subscriber's telephone by operation of the calling subscriber's telephone. A device installed in a telephone that is connected to a switching network that can control the length of the ringing signal being received, which includes a circuit that receives the ringing signal sent from the exchange while the telephone is on-hook, and a device that receives the received signal. a circuit that stores the signal; a circuit that analyzes the stored signal;
A signal information receiving device characterized by having a circuit that converts the signal into terminal control information based on the analyzed result, and a circuit that outputs the converted result.
