Abstract

PURPOSE:To connect directly a line wire subscriber capable of transmitting a PB signal and an extension subscriber by receiving and accumulating a PB number of an extension number from an originating party by means of a PB register, and connecting the corresponding extension telephone set to the originating party in accordance with the accumulated extension numbers. CONSTITUTION:When a two-way trunk or an input trunk 1' receives a calling signal, the trunk selects a talkie device 9 to transmit a guide talkie, etc., and a PB register 10 to receive and accumulate an extension number, returns a response signal to the originating party, and transmits the guide talkie, etc., from the talkie device 9. When a terminating subscriber transmits an extension dial by a PB number on the basis of this information, the PB register 10 receives and accumulates it. After completion of the reception, the register 10 activates a common controller 5 through a PB register connector 11, and the device 5 connects a line wire subscriber to an extension subscriber through a main link 7.

Description

[Detailed description of the invention] The present invention relates to an incoming call connection method for an in-channel switching device.

First, the incoming call connection method of a conventional private branch exchange device will be explained with reference to FIG. In FIG. 1, A is connected to a private branch exchange. Incoming calls from a general telephone office (incoming calls from outside lines)
If so, the bidirectional or incoming trunk 1 receives a ringing signal and the incoming call is connected to the reception console 3 via the seat device 2. The operator who receives the incoming call operates the response button on the reception desk 3 to talk to the caller on the outside line, operates the telephone key based on the transmitted extension subscriber information, and sends the extension number to the seat device 2. do. The seat device 2 sends a signal via the connector 4 to a common control device 5 which, by controlling the main link 7, connects the subscriber 8 of this extension with the outside caller. The above incoming call connection is a connection via a handler, and is a case where the incoming call is a ringing incoming call (16 Hz ringing signal).

Conventional private branch exchanges thus employ a system in which incoming calls are connected by an operator. Therefore, if the originator is a mechanized automatic calling device and the extension subscriber is also communicating in machine language using an automatic receiving device, there is a problem in that the originator and the extension subscriber cannot be connected. Another disadvantage is that the waiting time is long during call dispute hours.

The object of the present invention is to connect an automatic incoming call using machine language, for example,
Special terminal calling signals such as 1300H2's I#1% constant AC signal and incoming calls from terminals capable of sending PB double signals are automatically connected to the extension subscriber without going through a handler. To provide an incoming call connection method that does not require a dedicated telephone terminal and can reduce the number of handlers.

In order to achieve the above object, the incoming call connection system according to the present invention is based on the incoming call connection system of a local telephone exchange, in which each DP double signal and PB signal is assigned a corresponding pilot number and a corresponding trunk is provided. A PB signal register and a talkie device are installed in the trunk compatible with PR telephones.1. When you receive a call to your FB phone pilot number,
Activate the talkie device to send out a guidance talkie or the like to prompt the caller to dial an extension number, and then send the PB information of the extension number from the caller to the PB.
The system is configured to receive and store signals in a signal register, and to connect a corresponding extension telephone to a caller according to the stored extension number.

According to the above configuration, if the extension subscriber is an automatic call receiving device or if the caller is a terminal capable of sending a PB signal, connection can be made without going through a board, and the object of the present invention is completely achieved. be done.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 2 is a relay system diagram for explaining the incoming call connection system according to the present invention. In this figure, the same reference numerals are given to the same functional parts as in FIG. 1. When the two-way trunk or the incoming trunk 1' receives a calling signal (calling signal), it connects to a device 9 that sends out a guidance talker, etc., and P that receives and stores an extension number.
The B register 10 is selected, a response signal is returned to the originator, and a guidance talkie or the like is sent out from the talkie device 9.

When the originating subscriber sends a PB double signal for dialing an extension number using this 1fffa, the PB register 10 receives and stores this signal. Upon completion of reception, the PB register 10 activates the common control device 5 via the PB register connector 11, and the common control device 5 connects the outside line subscriber and the extension subscriber via the main link 7.

When the extension subscriber is busy, information to that effect is sent from the common control device 5 to the PB register connector 11 and the PB register lO.
to the bidirectional trunk or incoming trunk 1', which transmits a busy tone to the caller.

- In this way, it becomes possible to connect an external subscriber capable of sending a PB signal with an internal subscriber.

In recent years, the number of PB terminals has been increasing especially in public telephones and general telephones. PB of PB transmission according to the present invention
By enabling dial-in service to the X extension, it is possible to economically expand the service.
