Abstract

PURPOSE:To offer services to an originator of a PB telephone set and to enhance dial services by giving information of an additional dial from a talkie, etc., for incoming and by receiving an extension number or a repeating stand number, which are transmitted from the originator of the PB telephone set. CONSTITUTION:A talkie TKM, which can be connected to a trunk COT through a switch box ATT, a trunk line incoming trunk COT and a talkie trunk TTK, and a push button signal receiver PRT are connected to a private branch exchange PABX. When there is incoming at the trunk COT of the exchange PABX, the trunk COT is connected to the TTK, and the additional dial information is offered to an originator by the message recorded on the talkie TKM. After the message has been offered, the trunk COT is disconnected to the TTK, and the trunk COT is connected to the receiver PRT, thereby offering services to a calling party from a PB telephone set.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dial-in system using additional dials in an automatic private branch exchange, and more particularly to a system for instructing and guiding additional dials for one incoming call.

In conventional automatic private branch exchange equipment, if the caller from an outside line uses a pushbutton telephone (PB telephone), it is possible to provide a dial-in service that connects directly to the extension by additionally dialing the extension number. Although it is possible, if the caller does not know the extension number or the caller is not using an FB phone, it is necessary to have the call arrive at the central office line relay stand.

However, since it is not possible to determine at the time of receiving a call that the caller is using an FB phone and knows the extension number, conventional automatic private branch exchanges (PABX) connect all incoming calls from outside lines to a relay stand. That's what I do. That is, dial-in service is not provided.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide guidance to additional dialing of an extension number or attendant number for an incoming call, so that
The purpose of the present invention is to provide an additional dial guidance system that allows a caller from a B telephone to dial in by additional dialing.

Structure of the Invention The additional dial guidance system of the present invention is an automatic private branch exchange system having a central office line incoming trunk and a relay stand, which includes a button signal receiver and a talkie trunk.
In response to the incoming call to the I rank, the automatic private branch exchange connected the incoming call trunk to the key trunk of 11η, and gave instructions for additional dialing from the talkie device, etc. After that, the above-mentioned office line incoming call]-rank is connected to a button signal receiver, and the above-mentioned office line incoming trunk is connected to an extension telephone or relay stand by the button signal received by the button signal receiver, and the above-mentioned The present invention is characterized in that when the button signal receiver does not receive the button signal, the central office line incoming trunk is connected to the relay stand.

Embodiments of the Invention Next, the present invention will be described in detail with reference to the drawings.

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

That is, the automatic private branch exchange PABX, in addition to the conventional relay stand ATT and central office line incoming trunk COT, also receives central office line incoming trunks COT via talkie trunks TTK.
It is equipped with a talkie device TKM that can be connected to a button, and a button signal receiver PRT. Then, from the caller to the automatic private branch exchange PAB via the originating station and the terminating station,
When there is an incoming call on the central office line incoming trunk COT of X, as shown in Figure 2 (
As shown in A), the central office line incoming trunk COT and the 1-key trunk TTK are connected, and instructions for additional dialing are given to the caller using a message prerecorded on the talkie device TKM. For example, please dial the extension number. If you do not have the extension number ゎ, please dial 9°゛. After sending the message, the connection between the central office line incoming trunk COT and the talkie trunk TTK is disconnected;
As shown in FIG. 2(B), the central office line arrives at f7. Connect i+-rank COT and pushbutton signal receiver PRT. If the caller is an FB telephone, a signal from the extension number or number 9 sent from the caller is received by the button signal receiver PRT. As a result, the automatic private branch exchange PABX connects the central office line incoming trunk COT and the extension telephone STA as shown in (C), or connects the central office line incoming trunk COT and the extension telephone STA as shown in (D). Connect to relay stand ATT. That is, a dial-in service is provided. Since dials from callers other than FB telephones are not received by the pushbutton signal receiver PRT, the automatic private branch exchange PABX connects the central office line incoming trunk COT to the attendant stand ATT and allows the operator to call the caller. listen.

In place of the talkie device TKM of the embodiment described above, it is also possible to use a voice synthesizer in which similar messages are stored as digital signals, and to perform analog conversion of the messages using a codec. Also, without connecting the 1-station line incoming trunk COT to the relay stand ATT, the incoming call is displayed on the station line display panel and any extension phone i+! It is also possible to apply it to a distributed relay stand system in which i-machines can respond.

Effects of the Invention As described above, in the present invention, after an incoming call is given an instruction for additional dialing from a talkie device, etc., it is connected to a button signal receiver and sent from the caller of the FB telephone. Since the system is configured to receive the extension number or attendant number that is sent, it has the effect of being able to provide dial-in service to callers from PB telephones, and to provide dial-in services to callers other than PB telephones. It becomes possible to connect to a relay stand, etc.
