(54) DEVICE OF AUTOMATIC ROOM NUMBER

i

The invention relates to a telephone communication technique and can be used in telephone sets for abbreviated dialing.

It is known an automatic dialing device comprising a timer, the output of which is connected to the input of a divider, the first output of which is connected to the first input of the fixing unit, and the second output of the divider is connected to the first input of the control unit, the second input of which is connected to the record button, the third input of the control unit is connected with the read button, and the fourth input of the control unit is connected to the output of the fixation unit, the input of which through the contact is connected to the dialer, which is connected to the first input of the interface unit, at this The third divider output is connected to the second input of the interface unit, the third and fourth inputs of which are connected respectively to the first output of the control unit and the output of the storage device, and the upstream input of the interface unit is connected to the fifth input of the control unit (w, the first address and information outputs of which connected to the corresponding inputs of the storage unit 1.

However, the known automatic dialing device contains a large number of electromechanical playback contacts located on the front panel of the device, which greatly complicates the device.

The purpose of the invention is to simplify the device by excluding the name keyboard.

For this purpose, the automatic dialer contains a timer, the output of which is connected to the input of the divider, the first output of which is connected to the first input of the fixing unit, and the second output of the divider is connected to the first input of the control unit, the second input of which is connected to the record button, the third input of the block control unit is connected to the status button, and the fourth input of the control unit is connected to the output of the fixing unit, the input of which through the contact is connected to the dialer, which is connected to the first input of the interface unit, The third divider output is connected to the second input of the interface unit, the third and fourth inputs of which are connected respectively to the first output of the control unit and the output of the storage device, and the output of the interface unit is connected to the fifth input of the control unit, the first address and information outputs of which are connected to the corresponding inputs of the memory block, the subscriber's code lock was additionally entered, the input of which is connected to the second address output of the control unit, and the output of the subscriber code lock is connected to the control l yuschim input of the memory unit.

The drawing shows a structural elec. Trinisca scheme of automatic dialing.

The automatic dialing device circuit contains a timer 1, a divider 2, a fixation block 3, a control block 4, a write button 5, a read button 6, a contact 7, a telephone set 8 by a dialer or a keyboard, a conjugate block 9, a storage device 10, a latch 11 subscriber code. The fixing unit consists of a 12 daphras counter and a latch 13 digits. The interface block consists of break-free contact 14 and interface block 15.

The device automatically dials as follows.

In the initial state, the write button 5, the read button 6, the breakless contact 14 and the contact 7 are in the position shown in the drawing. At the same time, the telephone set 8 is connected to the subscriber line via break-free. Contact 14, and the automatic dialing device is disconnected from the subscriber line and the telephone dialing device 8. The subscriber is instructed to use the telephone set 8 in the normal mode, both upstream and downstream connection. When abbreviated dialing, abbyont picks up the handset of the telephone set 8 and, when the call back signal is received, briefly presses the read button 6. The signal is detected by the control unit 4, which closes contact 7 and connects the telephone set 8 to the fixing unit 3, and using unconnected coupling 14 disconnects the subscriber line from the telephone set 8 and connects it to the interface unit 15. After dialing by the subscriber using a dialer or a telephone dial-up telephone abbreviated number, for example, two ua {fr, the latter are fixed via the control unit 4 and in the lock 11 of the subscriber code. According to the signals of the control unit 4 and to the address of the number recorded in the latch II of the code abo720786

The storage device 10, where all the full numbers of the abbreviated subscriber numbers are called, starts sequentially through the conjugate block 9 the full number of your subscriber to the subscriber line. After the issuance of the full number of characters to the subscriber line of the full number of the subscriber’s subscriber, the control unit opens contact 7 and, by switching the break-free contact 14, switches the telephone

The unit 8 to the subscriber is deprived by providing

the subscriber is able to perceive stationary signals and make a conversation. With

refusal to install, connect during automatic dial operation

the subscriber hangs the microtelephone on the lever of the telephone set 8. At the same time, under the influence of the control unit 4, the contact 7 is opened and switched

pin 14,) is restored to its original position, in which the telephone 8 is connected to the subscriber line. In the mode of recording or rewriting the full number of the subscriber button 5 records.

The signal is received by the control unit 4, which closes the contact 7 and connects the telephone set 8 to the fixing unit 3, and the positive contact 14 disconnects the subscriber line from the telephone set 8.

After that, the subscriber dials or dials the telephone 8, for example, dials two digits of the abbreviated dialing code (address) and then the full subscriber number intended for storage in the memory

device 10 at the address specified by the abbreviated dialing code. Through the control unit 4, the first two digits, determined by the abbreviated dialing code, as well as in the playback mode, are fixed in the lock 11 of the subscriber code. The subsequent digits of the full subscriber number from the latch 13 digits through the control unit 4 are alternately transmitted by the TEO to the address and information outputs in the storage device 10 and fixed in the corresponding word defined by the latch 11 of the subscriber code. In this case, the information found previously in the cells of the storage device 10 is automatically erased. At the end

Record the subscriber lowers the microphone with the handset on the lever of the telephone sets and opens the record button 5. Control unit 4 opens contact 7 and restores the initial position of the ycipoAciBa automatic

dialing a number. In the initial state, the device is ready to play the recorded full number of the called subscriber when dialing the caller-abbreviated code of the full number. Thus, the proposed automatic dialing device compared to; With a known device, by inserting a subscriber code identifier, it is possible to reject a large number (by the number of memorized subscriber numbers) of electromechanical contacts and bring the service discipline closer to that received by subscribers during normal telephone use. apparatus and, in particular, to the discipline of using the service of reduced dialing in a program-controlled PBX. The invention The automatic dialing device containing a timer, the output of which is connected to the input of a divider, the first output of which is connected to the first input of the fixing unit, and the second output of the divider is connected to the first input of the control unit, the second input of which is connected to the record button, the third input of the control unit connected to the read button, and the fourth input of the control unit soy ;; Dinen with an output, a fixation unit, whose input is connected through a contact to a telephone set that is connected to the first input of the interface unit, while the third output of the divider is connected to the second input of the interface unit, the third and fourth inputs of which are connected respectively to the first output of the unit control and the output of the storage device, and the output of the interface unit is connected to the fifth input of the control unit, the first address and information inputs of which are connected to the corresponding inputs of the storage unit, characterized by in that, in order to simplify the device by avoiding nominal keypad additionally introduced subscriber code latch having an input coupled to the second output of the address control unit, and the local code latch output is connected to the control input of the memory unit.
