JPH02265352A - Hold music generator for PBX connection - Google Patents

Abstract

PURPOSE:To facilitate the revision of a tone kind of a holding tone without giving adverse effect on the system by constituting the system with a means generating a melody or a simulating tone, a means storing the information of the generated tone and a power supply means and connecting them to a PBX. CONSTITUTION:A tone generator 4 consists of an IC1 used as a means generating a melody or a simulating tone, a ROM 2 used as a means storing the information of a generated tone, and a peripheral circuit 3 assisting a circuit including the IC1 and the ROM 2. The tone is generated by allowing the IC1 to control the sound information stored in the ROM 2 and its output is given from a LINEOUT terminal 7. Thus, a holding tone going through a PBX line is easily revised without giving effect on the system.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to P B
H-exchange (private branch telephone exchange) system related to hold music.

[Prior art] The hold tone used when using a private telephone is conventionally called PB.
It uses the sound generated from the circuit built into the X.

This circuit uses a sound generating IC called a melody IC, which has data such as songs written in advance.

[Problem to be solved by the invention]

When changing the oil type, one possible method is to change the built-in melody IC to another melody IC with a different type of song, but in this case, it is necessary to modify the inside of the PBX. This is not a recommended method as it may have a negative effect on the system.

SUMMARY OF THE INVENTION An object of the present invention is to easily change the sound type of a hold tone installed in a PBX system without adversely affecting the system.

[Means for Solving the Problems] The present invention comprises a means for generating a melody or onomatopoeic sound, a means for storing information on the generated sound, and a power supply means, and is connected to a PBX to generate a melody or an onomatopoeic sound. A special feature characterized in that the sound is played on a private line managed by the PBX and a public telephone line connected to the PBX [Embodiment] Fig. 1 is a diagram schematically showing a device according to the present invention. . The sound generation bag ff3 is composed of an ICI used as a means for generating a melody or an onomatopoeic sound, a ROM2 used as a means for storing information on the generated sound, and a peripheral circuit 3 that assists the circuit including the I(, L, ROM2). has been done.

This device operates with power supplied from AClooV.

The sound is generated by controlling the sound information stored in the ROM 2 by the ICI, and the output is performed from the LINE OUT terminal 7.

Figure 2 is a diagram showing an example of the connection between a PBX and this device.
Connect to external input terminal 9. When the PBX is set to send the input from the external input terminal 9 to the line in response to a hold music start command from the local terminal telephone, the sound generated from this device flows to the line.

When changing the sound, it can be easily done by replacing the ROMI, which is built into the sound generating device in a removable socket manner.

Furthermore, the connection to the PBX will not have any adverse effect on the PBX system as long as impedance matching with the external input terminal 9 of the PBX is achieved.

〔Effect of the invention〕

By using this device, the hold tone flowing through the PBX line can be easily changed without affecting the system.
