Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange with a call volume level control function.

[Conventional technology]

Conventionally, in this type of private branch exchange, fixed call volume level data is set for each call circuit at some stage during the installation work of the private branch exchange, and when setting up the call circuit, the volume level variable unit connected is set using this data. The level of call volume for each call circuit was controlled by adjusting the data.

[Problem that the invention seeks to solve]

The conventional private branch exchange described above controls the call volume level by fixing the volume level for each call circuit, so even if you set the call volume level suitable for each call circuit, the voice may be too low or There is a drawback that the optimum call volume is not always achieved due to variations in the amount of transmission (transmission) on subscriber lines, such as ``this time the voice is too loud.''

[Means for solving problems]

The private branch exchange with call volume level control function of the present invention includes a volume control special number memory that stores a volume control special number, and a per-dial volume level variable that stores per-dial volume level variable value data determined or modified for each dial. The main storage device includes a value memory, reads the volume control special number sent from the extension terminal during a call, then reads the call volume level information sent from the extension terminal, and according to this call volume level information, dial information reading means for correcting dial volume level variable value data stored in the dial volume level variable value memory; and dial information reading means correcting the dial volume level variable value data stored in the dial volume level variable value memory; When the volume level variable value data is sent to a vacant volume level variable unit and the volume level variable unit is connected to the telephone circuit, the volume level of the telephone circuit is determined by the volume level variable value data sent to the volume level variable unit. The central processing unit is provided with a connection control means for adjusting the volume level variable unit so as to achieve the desired volume level, and connecting the volume level variable unit between the extension terminal and the outside line interface trunk.

[For production]

When the extension terminal sends the volume control special number and subsequently sends the call volume level information to be set, the dial information reading means stores the input call volume level information in the dial whistle volume level variable value storage area. The connection control means selects an empty volume level variable unit, sends the corrected dial volume level variable value data to the empty volume level variable unit, and adjusts the volume of the call circuit. Since the volume level variable unit is adjusted so that the volume level corresponds to the corrected data, the volume level of the call circuit can be set arbitrarily by inputting the call volume level information by dialing from the extension terminal. As a result, you can make calls at the optimal call volume level.
