JPH02261251A - Adaptor for trunk line attendant board - Google Patents

Abstract

PURPOSE:To identify the call class of an attendant board and a call state in an audible tone by connecting a trunk line attendant board adaptor between an electronic exchange and a trunk line attendant board. CONSTITUTION:A trunk line attendant board adaptor 10 receives lamp information controlling blink of a lamp from an electronic exchange 1 with a serial data reception circuit 2, and a CPU 3 discriminates the coincidence between a received data and any of lamp information stored in advance in a memory 4. When they are dissident, the succeeding reception data is awaited, and when they are coincident, a selection circuit 6 gives a command to select a sound corresponding to lamp information among tones generated in an audible tone generating circuit 5. An audible signal corresponding to the lamp information is superimposed with a voice signal by an adder circuit 7 and the result is outputted to a trunk line attendant board 9 via an amplifier circuit 8. As a result, the operator of the trunk line attendant board 9 identifies the call class and the call state by the lamp blink display in an audible tone.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an additional device for a central line relay stand of an electronic exchange.
In particular, the present invention relates to an additional device that communicates the status of a central office line relay stand to a central office line relay stand operator using a method other than visual recognition.

[Conventional technology]

Conventionally, general office line relay consoles communicate the type of incoming call and the status of the call to the office line relay console operator using lamps, liquid crystal displays, and sound. In this case, various types of calls, such as the distinction between incoming external calls and incoming internal calls, were all indicated by lamps, and the role of sound was merely to alert the caller to the presence of an incoming call.

[Problem to be solved by the invention]

The above-mentioned conventional general office line relay board that transmits call type information and status information using lamps is changed to a central office line relay board that allows the central office line relay board operator to recognize the information by means other than visual recognition. In order to do this, there is a problem in that the internal structure of the electronic exchange or central office line relay board must be changed, or it must be replaced with a dedicated central office line relay board.

[Means to solve the problem]

The present invention provides a central office line relay stand additional device connected between a central office line relay stand and an electronic exchange, including means for receiving lamp control information sent from the electronic exchange to the central office line relay stand; means for determining whether the lamp control information received by the means matches any of a plurality of pre-stored lamp control information; The present invention is characterized by comprising means for generating a predetermined sound and superimposing it on the audio signal sent from the electronic exchange to the central office line relay board.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention.

In this figure, the office line relay stand addition device 10 includes a serial data receiving circuit 2 that receives lamp information in serial data format based on a digital signal from an electronic exchange 1, a microprocessor 3, a memory 4, and an audible sound selection circuit. 5, an audible sound selection circuit 6 that selects an audible sound corresponding to lamp information from the microprocessor 3, an addition circuit 7 that adds the audio output of the electronic exchange 1 and the output of the audible sound selection circuit 6, and an addition circuit. AMP (amplifier circuit) 8 for amplifying the output of 7, and is connected to the exchange 1 and the office line relay board 9.

When the serial data receiving circuit 2 receives lamp information for controlling lamp blinking from the electronic exchange 1, the microprocessor 3 determines whether the received data matches any of a plurality of lamp information stored in the memory 4 in advance. Determine whether or not. As a result, if there is a mismatch, the next received data is waited for, and if there is a match, the audible sound whose correspondence with the lamp information is determined in advance is selected from among the plurality of audible sounds generated by the audible sound generation circuit 5. A command is issued to the listening selection circuit 6 to make a selection. The audible sound signal corresponding to the lamp information sent from the electronic exchange in this way is superimposed on the audio signal by an adder circuit 7, amplified by an AMP (amplifier circuit) 8, and output to a central office line relay board 9. As a result, the station line relay stand operator is displayed by flashing lamps. It becomes possible to identify the type of incoming call at the office line relay stand and the state of the call using audible sounds.

Although this embodiment shows an example using a microprocessor, the same thing can also be implemented using a logic circuit.

In addition, in this embodiment, the lamp information is identified using the audible sound generation circuit 5 and the audible sound selection circuit 6, but it is also possible to change this to a voice synthesis circuit and communicate the information to the station relay stand operator in words. be.

〔Effect of the invention〕

As explained above, the present invention is capable of identifying and distinguishing between the office line relay stand, the type of incoming call, and the state of the call using audible sounds by connecting the office line relay stand additional device between the electronic exchange and the office line relay stand. The effect is that recognition other than visual perception can be made possible without replacing the basic relay stand or making any internal modifications.
