Abstract

PURPOSE:To facilitate the shift of a telephone set between telephone terminals by rewriting the data on the store position information corresponding to the number given to the telephone set by a controller of a private telephone exchange device and varying the storage of the telephone set into the private telephone exchange device. CONSTITUTION:When a calling subscriber hooks off a handset, a private telephone exchange device EPBX executes a registeration action and sends a dial tone to the calling subscriber. Then the calling subscriber dials a special number through a manual dial device 32, and therefore the special number is fetched into a CPU15 from an outgoing register 20. The CPU15 recognizes the shift request of the telephone set from the special number and then replaces the subscriber interpretation data recorded on a magnetic drum 14 with a subscriber unstored state. Then the telephone set is connected to a store terminal l21 to perform an originating operation. Thus the information on the store position l21 is recorded to the subscriber interpretation data corresponding to a telephone 22 in a drum 14. As a result, the CPU15 closes a channel to the terminal l21.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a variable accommodating system for a private branch exchange (hereinafter abbreviated as EPBX) using a storage program control system.

(b) Conventional technology and problems Conventionally, the method of accommodating telephones in an EPBX has been to physically fix them, and replacing the telephones requires changing the jumper at the distributor and installing the telephones in the EPBX. This was done by rewriting data related to the accommodation of telephones held by the EPHX through service processing performed from a maintenance typewriter or equivalent input/output device. FIG. 1 is a diagram of a conventional relay system, in which a telephone terminal 10 is connected to a telephone network (NW) 12 through a distributor 11.
At the terminal, the incoming trunk (ICT) 13 is directly connected to the communication path 12.
connected to. It also includes a central control unit (CPU) 15 for controlling the communication path, a magnetic drum (MD) 14, and an input/output typewriter (TYP) 16. Here, a case in which a call is received at the telephone set 10 will be explained step by step with reference to FIG. 1. Now, the central control unit [15 is in trunk 13
When an incoming call is detected by a scanning device (not shown), the incoming subscriber is accommodated using the subscriber translation data stored in the magnetic drum 14 based on the called number received by a numeric receiver (also not shown). The location JIO is translated and a call path is closed through the call path 12 to allow the subscriber to receive the call. When moving the subscriber's telephone 10 from the accommodation position JIO to Jll in the case of the above-mentioned incoming call method, the central control unit 15 first analyzes the operator's instructions to the input/output tag writer 16, and determines whether the telephone 10 is not accommodated or not. The subscriber translation data stored in the magnetic drum 14 is changed so as to indicate the state. In this state, incoming calls to the phone are EPB.
Since it is rejected by X, the tj1 talk machine is next accommodated from the accommodation terminal 1xo to the accommodation terminal 1x1 by the jump of the distributor 11. Thereafter, the central control unit 15 analyzes the operator's instructions on the input/output typewriter 16 and changes the storage position of the subscriber translation data stored in the magnetic drum 14 corresponding to the telephone set 10 from 110 to Jll. By the above operation, subsequent incoming calls to the telephone set 10 are connected to the reception station vJ11. As explained above,
1 has the drawback that when the packing machine is housed in a different accommodation position, the telephone cannot be moved to another accommodation terminal because there are many operating procedures and it takes time.

(C1 Object of the Invention The present invention improves the conventional drawbacks and improves the telephone set and the E P
The purpose of this invention is to provide a variable telephone system in which telephones can be changed in a short period of time by changing the incoming telephone number and transmitting information to and from an AC signal.

(d) Summary of the Invention The variable telephone accommodation system of the present invention is based on EP 13 In addition, the EPBX is provided with a means for requesting the telephone to send a calling number using an AC signal and a means for receiving the calling number from the telephone; A request is made to the calling telephone to send the calling number using an AC signal, and the telephone automatically sends the calling number upon receiving the AC signal.
X is characterized by having a means for rewriting the take of accommodation location information for a telephone number given to a telephone based on the calling number, thereby making the accommodation of the telephone in the EPBX variable.

(e) Examples of the invention Next, the present invention will be explained with reference to the drawings.

FIG. 2 is a relay system diagram showing an embodiment of the present invention,
An outgoing register (OR) 20 is connected to the communication path 12, and an AC signal transmitter (0
8C) 21 is connected. A telephone set 22 having an AC signal detection function is connected to the communication line 11 via the distributor 11, and the other parts are the same as in FIG. FIG. 3 shows a functional block diagram of the telephone 22 shown in FIG.
The system includes an automatic dialing device 35, a control device 33, a manual dialing device 32, a telephone network 3o, and a switching device 31.

The operation of the present invention will be explained in order below with reference to FIGS. 2 and 3. Now, when the subscriber hooks up the handset of the telephone 22, the control device 33 on the telephone side connects the central office line 13G to the AC signal receiver 34 through the switch 31, and at the same time transmits the signal to ET)B Close the loop. The EPIIX central control unit 15 detects the call using a scanning device (not shown) and connects the calling register 2° to the 1[j1 telephone set 22 that made the call through the communication path 12. When the communication path is completed, the central controller e, 15,
The calling register 2o and the AC signal transmitter 21 are controlled to send an AC signal for requesting a calling number to the calling telephone 22 for a certain period of time.

The alternating current (No. 8) is detected by the alternating current signal detector 34 of the telephone 22, and the alternating current signal detector 34 notifies the control device 33 of the information. The control device 33 activates the automatic dialing device 35, The calling number individually assigned to the telephone set 22 is automatically sent. After the sending is completed, the control device 33 switches to the manual dialing device 32. The calling number sent by the telephone set 22 is input to the calling register 2°. 0 received
The central control unit 15 indexes the subscriber translation data recorded on the magnetic drum 14 based on the currently received calling number, and places the telephone that has just made the call at the accommodation position 12o in the corresponding position.
□ After the writing of the subscriber translation data is completed normally, the central control unit 15 controls the calling register 20 to send a dial tone to the telephone 22. The calling subscriber opens the dial tone and dials the manual dialing device 32.
dials the terminating subscriber's number and establishes a known outgoing connection. In this way, the registration operation of the subscriber accommodation terminal is automatically performed each time a call is made. Now, let us consider the case where the telephone 22 is replaced with the accommodation terminal 121. In this case, the calling subscriber can access the EPB by going off-hook.
X performs the registration operations described above and then sends a dial tone to the calling subscriber. The calling subscriber dials the special number by manual dialing device 32. The special number is read into the outgoing register 20 and taken into the central control rack [15]. The central control unit 15 recognizes that the special number is a request to move the stain filler, and in the same manner as the previous registration operation, the central control unit 15 records the calling number on the magnetic drum 14 using the received calling number from the telephone 22. The existing subscriber translation data is replaced with the status of subscriber old age accommodation. If there is an incoming call to the telephone in this state, it will be marked as busy. Next, place the phone in the terminal, ff
