Abstract

PURPOSE:To select a specific expansion network terminal equipment corresponding to a caller telephone number automatically, to attain immediate talking, to evade waste of useless wait time and to eliminate the need for an operator by providing a storage means for an expanded network terminal number and a control means. CONSTITUTION:When a call comes to an interface 5 of an automatic exchange from an external network 1, a CPU 8 retrieves a terminal number of an expansion network 2 corresponding to a data stored in a ROM 7 from a caller telephone number. When a number, 01 is retrieved, a terminal number 01 is read, added to the caller telephone number and the result is outputted from an interface 6 to the network 2, a specific terminal equipment such as a telephone set 3a is called to terminate the exchange. Thus, since a specific terminal equipment is immediately called automatically at the arrival of the call, waste of useless waiting time for the exchange is evaded and no operator is required.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is capable of notifying a caller's telephone number.
The present invention relates to an automatic switching device used in a private branch exchange or the like that connects a network such as 5DN to an extended network.

2. Description of the Related Art Conventionally, when a call is received from an external network to a switching equipment, the switchboard talks with the caller and manually connects to the recipient's telephone based on the terminal number of the extended network provided, or The terminal number of the extended network was determined from the recipient's name, and the connection was made manually to the recipient's phone.

Problems to be Solved by the Invention However, in the conventional switching system as described above, after a call is received, it wastes waiting time until the caller is connected to the desired recipient, and furthermore, the switching process requires manpower. There were issues such as the need for

The present invention solves these conventional problems, and automatically selects a specific extended network terminal corresponding to the caller's phone number so that the call can be made immediately, thereby eliminating unnecessary waiting time. It is an object of the present invention to provide an automatic exchange device that eliminates the need for a switch operator.

Means for Solving the Problems In order to achieve the above object, the present invention provides a storage means in which one extended network terminal number is stored in advance in association with each calling number from an external network, and a When a call is received, control means is provided for searching and calling an extended network terminal number corresponding to the caller's telephone number from the storage means.

Therefore, according to the present invention, when a call is received from an external network, the control means searches the storage means and reads out the terminal number of the extended network corresponding to the caller's telephone number stored in the storage means, The caller can call a specific terminal on the extended network that he or she wants to talk to.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic block diagram showing an automatic switching device in one embodiment of the present invention.

In FIG. 1, 1 is an external network, such as rsDN, which can notify the caller's telephone number, and 2 is an extended network, which includes a plurality of terminals 3as, 3bs, and so on. Reference numeral 4 denotes an automatic switching device of the present invention, which includes interfaces 5 and 6 connected to an external network 1 and an extended network 2, and one extended network terminal corresponding to each caller's telephone number from the external network 1. A read-only memory (hereinafter referred to as ROM) 7 in which a number is stored in advance, and an interface 5.
6, and when there is an incoming call from external network 1, R
The CPU 8 searches the OM 7 and reads out the extended network terminal number corresponding to the caller's telephone number stored in the ROM 7.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG.

When an incoming call is received from the external network 1 to the interface 5 of the automatic switching device of the present invention (step 20), the CPU 8 uses the telephone number of the caller to find the corresponding terminal of the extended network 2 in the data stored in the ROM 7. When the number is searched (step 21) and, for example, Ol is searched, this terminal number 01 is read out, added to the caller's telephone number, outputted from the interface 6 to the extended network 2, and is sent to a specific terminal, for example 3a. A certain telephone is called (step 22) and the exchange operation is completed (step 23).

Effects of the Invention As described above, according to the present invention, there is provided a storage means in which one extended network terminal number is stored in advance in association with each calling number from an external network, and a The controller is equipped with a control means that searches the storage means for an extended S terminal number corresponding to a person's telephone number and calls it, so that when a call is received from an external network, the control means searches the storage means and stores it in the storage means. The extended network terminal number corresponding to the caller's telephone number is read out, and the caller can call a specific terminal on the extended network with which the caller wishes to make a call. Therefore, since it is possible to automatically call a specific terminal immediately upon receiving a call, it is possible to eliminate unnecessary waiting time for switching operations, and it is also possible to eliminate the need for a switch operator.
