JPH0246054A - Automatic exchange with incoming call sound control function - Google Patents

Abstract

PURPOSE:To set optimum incoming call sound corresponding to the ambient environment of a subscriber by changing the level and the cycle of the incoming call sound transmitted from an incoming call transmitting circuit based on incoming call sound control data. CONSTITUTION:On calling a subscriber 4, a central control unit 3 transmits incoming call sound control data set in advance to a subscriver's circuit 2. The subscriber's circuit 2 controls incoming call sound level variable equipment 6 and an incoming call sound cycle variable relay 7 based on the incoming call sound data by an incoming sound control circuit 8. Incoming call sound transmitted from an incoming call sound transmitting circuit 5 is transmitted to the subscriber 4 as the incoming call sound of which level and cycle are set by the incoming call sound levelvariable equipment 6 and the incoming call sound cycle variable relay 7. Thus, by adding the incoming call sound control circuit at the every subscriber's circuit and changing the level and the cycle of the incoming call sound to the every subscriber, the optimum incoming call sound corresponding to the circumferential environment of the subscriber can be set.

Description

[Detailed description of the invention] [Industrial application field 1 The present invention relates to a ring tone control method in an automatic exchange.

[Conventional technology]

In conventional automatic switching systems, the ring tone signal is distributed from the ring tone transmission circuit to each subscriber for use, so the ring tone for all subscribers is the same depending on the conditions of the ring tone transmission circuit. Ta.

[Problems to be Solved by the Invention] In the conventional ringtone control method described above, the ringtone is transmitted depending on the conditions of the ringtone sending circuit, so
The disadvantage is that the ringtone is too low to be heard in noisy places, and too loud in places where silence is required, such as conference rooms and hospital beds.

[Means for Solving the Problems] The automatic exchange of the present invention includes a ring tone control circuit for each subscriber circuit, which changes the level and period of the ring tone sent from the ring tone sending circuit based on ring tone control data. have in
The central controller is characterized in that it sends ringtone control data to the ringtone control circuit.

[Function] Therefore, it is possible to set the optimal ring tone according to the subscriber's surrounding environment.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a relay system diagram of an embodiment of an automatic exchange with a ring tone control function according to the present invention, and FIG. 2 is a block diagram of a subscriber circuit 2. In FIG. Note that this embodiment is an example of an automatic exchange using a storage program control method.

A subscriber 4 is accommodated in the communication path switch 1 via a subscriber circuit 2. The subscriber circuit 2 accommodating the subscriber 4 is
a ringtone level variable device 6, a ringtone cycle variable relay 7,
It includes a ringtone control circuit 8 that controls these based on ringtone control data sent from the central control device 3.

Next, the operation of this embodiment will be explained.

When calling the subscriber 4, the central control device 3 sends preset ring tone control data to the subscriber circuit 2. The subscriber circuit 2 controls the ring tone level variable device 6 and the ring tone period variable relay 7 by the ring tone control circuit 8 based on the ring tone control data, and controls the ring tone sent from the ring tone sending circuit 5 to receive the ring tone. The sound level variable device 6 and ring tone cycle variable relay 7 send the ring tone to the subscriber 4 as a ring tone whose level and cycle are set.

〔Effect of the invention〕

As explained above, the present invention adds a ring tone control circuit to each subscriber circuit, and allows the level and cycle of the ring tone to be changed for each subscriber. This has the effect of allowing you to set the optimal ringtone.
