Abstract

PURPOSE:To send a holding tone to a 2nd subscriber by providing a means receiving a holding tone transmission request from a 1st subscriber and a means sending the holding tone to the 2nd subscriber to an exchange accommodating the 2nd subscriber when the 1st subscriber and the 2nd subscriber are busy with each other. CONSTITUTION:When subscribers 1, 7 are busy and the subscriber 1 sends a holding tone transmission request by a dial signal, the dial signal is fed to a subscriber circuit 6 via a subscriber circuit 2, an exchange 3, a transmission line 4 and an exchange 5. When a channel controller 9 recognizes it that the subscriber circuit 6 receives a holding tone transmission request signal from the subscriber 1, the controller 9 controls a holding transmitter 8, which sends a holding tone to the subscriber 7 via the subscriber circuit 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a music-on-hold service system in an asynchronous transfer mode switching system.

[Conventional technology]

As a conventional music-on-hold service system, there is a system in which when a subscriber who is talking on a call puts the call on hold and sends the music on hold to the other subscriber, the subscriber terminal holding the call sends the music on hold.

[Problem to be solved by the invention]

The above-described conventional music-on-hold service system has a drawback in that a subscriber terminal sends music on hold to the other subscriber, so a transmission channel is required to send the music on hold.

[Means to solve the problem]

The music-on-hold service method of the present invention is a music-on-hold service method for an asynchronous transfer mode switching system in which a plurality of exchanges accommodating subscribers are connected via a transmission path. a receiving means for receiving a holding music sending request for the second subscriber; and a sending means for sending the holding music to the second subscriber when the receiving means receives the holding music sending request; It is provided in the exchange that accommodates the subscribers.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. Subscriber 1 connects via subscriber circuit 2 to exchange 3 in asynchronous transfer mode.
The exchange 3 is connected by a transmission line 4 to an exchange 5 in an asynchronous transfer mode. The exchange 5 accommodates a subscriber 7 via a subscriber circuit 6, and is also connected to a hold music sending device 8. Exchange machine 5. The subscriber circuit 6 and the hold tone sending device 8 are controlled by a communication path control device 9.

The operation will be explained below.

When subscriber 1 and subscriber 7 are talking, when subscriber 1 sends a hold tone transmission request using a dial signal, this dial signal is sent to subscriber circuit 2. Exchange 3, transmission line 4. When the 0 communication path control device 9, which is transmitted to the subscriber circuit 6 via the exchange 5, learns that the subscriber circuit 6 has received the hold tone sending request signal from the subscriber 1, it sends the hold tone sending bag W8. control,
The hold music sending device 8 sends hold music to the subscriber 7 via the subscriber circuit 6.

When subscriber 1 resumes the call, the voice signal from subscriber 1 is transferred to subscriber circuit 2. Switchboard 3. The signal is transmitted to the subscriber circuit 6 via the transmission line 4 exchange 5. When the communication path control device 9 learns that the subscriber circuit 6 has received the voice signal from the subscriber 1, it controls the hold tone sending device 8, and the holding tone sending device 8 sends the hold tone to the subscriber 7. stop.

〔Effect of the invention〕

As described above, the present invention provides a means for receiving a hold music transmission request from a first subscriber when a first subscriber and a second subscriber are talking in an asynchronous transfer mode switching system. By providing a switch accommodating the second subscriber with a means for transmitting hold music to the second subscriber, the first When the second subscriber puts the call on hold, the hold tone can be sent to the second subscriber.

Claims (1)

[Claims] In a music-on-hold service system of an asynchronous transfer mode switching system in which a plurality of exchanges accommodating subscribers are connected by a transmission path, a request from a first subscriber to send music on hold to a second subscriber who is in the middle of a call is made. an exchange for accommodating the second subscriber, comprising: receiving means for receiving the held tone; and sending means for transmitting the held tone to the second subscriber when the receiving means receives the held tone sending request. This music-on-hold service system is characterized by:
